(704 words) ## Articles & Blog Posts - [Create File - Flex Documentation](/content/docs/api-reference/files/create-file/index.html): Uploads a file to Flex. The request must be a multipart/form-data upload containing a file part and a purpose part. The file must be a JPEG, PNG, or PDF no larger than 5 MB; PNGs using 16-bit depth or Adam7 interlacing are rejected. The uploaded file can then be referenced by ID elsewhere in the API, for example as evidence on a dispute. Requires the files_write scope. (356 words) - [Retrieve File - Flex Documentation](/content/docs/api-reference/files/retrieve-file/index.html): Retrieves the details of an existing file. Supply the unique file ID that was returned when the file was uploaded. Requires the files_read scope. (261 words) - [List Files - Flex Documentation](/content/docs/api-reference/files/list-files/index.html): Returns a list of your files, sorted by creation date with the most recently created files first. Pass purpose to filter to a single file purpose. Requires the files_read scope. (254 words) - [Retrieve a capture - Flex Documentation](/content/docs/api-reference/captures/retrieve-a-capture/index.html): Retrieves the details of a capture. Use the expand query parameter to inline related objects (such as the payment intent). (288 words) - [Update a capture - Flex Documentation](/content/docs/api-reference/captures/update-a-capture/index.html): Updates the specified capture by setting the values of the fields you pass; only metadata can be changed. Other capture fields, including captured amounts, cannot be modified. (381 words) - [List captures - Flex Documentation](/content/docs/api-reference/captures/list-captures/index.html): Returns a list of your captures. Optionally filter to a single checkout session with the checkout_session query parameter, and expand related objects (such as the payment intent) with expand. (298 words) - [Create Setup Intent - Flex Documentation](/content/docs/api-reference/setup-intents/create-setup-intent/index.html): Creates a SetupIntent to collect a customer's payment method details for future off-session use. A new SetupIntent is created on each call and starts in the requires_payment_method status; it is not an upsert. The response includes a client_secret that you use to confirm the SetupIntent and attach a payment method from your frontend. (333 words) - [Get Setup Intent - Flex Documentation](/content/docs/api-reference/setup-intents/get-setup-intent/index.html): Retrieves the details of an existing SetupIntent. The response includes a fresh client_secret for confirming the SetupIntent from your frontend. Pass expand=subscription to inline the associated Subscription, when one exists. (380 words) - [List Setup Intents - Flex Documentation](/content/docs/api-reference/setup-intents/list-setup-intents/index.html): Returns a list of SetupIntents, sorted by ID in descending order (most recent first). The client_secret is not included on listed SetupIntents; retrieve a SetupIntent individually to obtain it. (418 words) - [List Balance Transactions - Flex Documentation](/content/docs/api-reference/balance-transactions/list-balance-transactions/index.html): Returns a list of Balance transactions. (369 words) - [Update Subscription - Flex Documentation](/content/docs/api-reference/subscriptions/update-subscription/index.html): Updates an existing subscription. Any omitted field is left unchanged, and an empty request body is a no-op that simply returns the current subscription. The change is first applied in Stripe and then mirrored to Flex, so the response reflects the resulting status and billing period. Updating items switches each item to the supplied recurring price (or to a newly created price when price_data is given, in which case a new Price is created in Stripe and Flex); item prices must be recurring. proration_behavior controls how mid-cycle changes are prorated (create_prorations by default). Supplied metadata is merged into any existing metadata. Passing an empty string for coupon removes the current coupon. (426 words) - [Cancel Subscription - Flex Documentation](/content/docs/api-reference/subscriptions/cancel-subscription/index.html): Cancels a customer's subscription. By default the subscription is canceled immediately; set cancel_at_period_end to true to keep it active until the end of the current billing period instead. Optionally issue a refund as part of the cancellation by setting refund to full, prorated, or custom (a custom refund requires a positive refund_amount in the smallest currency unit). Refunds are processed as a separate operation from the cancellation. The request body is optional; omitting it cancels immediately with no refund. (365 words) - [Get Subscription - Flex Documentation](/content/docs/api-reference/subscriptions/get-subscription/index.html): Retrieves the subscription with the given ID. Use expand (or expand_customer) to inline related objects such as the customer, latest invoice, default payment method, or item prices. (275 words) - [Resend Subscription Receipts - Flex Documentation](/content/docs/api-reference/subscriptions/resend-subscription-receipts/index.html): Resends existing receipt emails for the initial checkout of a subscription. Looks up the receipts for the subscription's initial checkout-session payment and enqueues them to be emailed to the customer; the existing receipt PDFs are reused, not regenerated. (254 words) - [Get Refund Preview - Flex Documentation](/content/docs/api-reference/subscriptions/get-refund-preview/index.html): Previews the prorated refund that would result from canceling a subscription. Runs the same validation as a real prorated refund but issues no refund and creates no records, so it is safe to call repeatedly. Returns the prorated amount available to refund, the amount paid on the latest invoice, the current billing period, and the card that would be refunded. (344 words) - [List Subscriptions - Flex Documentation](/content/docs/api-reference/subscriptions/list-subscriptions/index.html): Returns a list of your subscriptions, most recent first. Optionally filter by customer or status. Use expand (or expand_customer) to inline related objects such as the customer, latest invoice, or item prices. (284 words) - [Get Review - Flex Documentation](/content/docs/api-reference/reviews/get-review/index.html): Retrieves the details of a fraud review. (289 words) - [List Reviews - Flex Documentation](/content/docs/api-reference/reviews/list-reviews/index.html): Returns a list of your fraud reviews, newest-first. Use the open filter to focus on reviews that still need action. (327 words) - [Update Refund - Flex Documentation](/content/docs/api-reference/refunds/update-refund/index.html): Updates the reason and/or metadata of an existing refund. Only these two fields can be changed; the refund amount, status, and associated payment cannot be modified after creation. Supplied metadata keys are merged into any existing metadata. (400 words) - [Create Refund - Flex Documentation](/content/docs/api-reference/refunds/create-refund/index.html): Creates a refund for a previously succeeded payment intent and returns the resulting Refund. The referenced payment intent must have a succeeded status. If amount is omitted, the full amount of the payment intent is refunded. A refund.created event is emitted, and the returned refund's status may still be pending; subsequent status changes are delivered via webhooks. (383 words) - [Get Refund - Flex Documentation](/content/docs/api-reference/refunds/get-refund/index.html): Retrieves the details of an existing refund by its ID. (268 words) - [List Refunds - Flex Documentation](/content/docs/api-reference/refunds/list-refunds/index.html): Returns a list of your refunds, most recent first. (333 words) - [Create Promo Code - Flex Documentation](/content/docs/api-reference/promo-codes/create-promo-code/index.html): Creates a promotion code referencing an existing coupon. If code is omitted, a unique code is generated automatically. The supplied code must be unique across your promotion codes. (363 words) - [Update Promo Code - Flex Documentation](/content/docs/api-reference/promo-codes/update-promo-code/index.html): Updates a promotion code by its ID. Only active and metadata can be modified; the referenced coupon and the code are immutable. (470 words) - [Get Promo Code - Flex Documentation](/content/docs/api-reference/promo-codes/get-promo-code/index.html): Retrieves a promotion code by its ID. (293 words) - [Create Export - Flex Documentation](/content/docs/api-reference/exports/create-export/index.html): Creates an export and starts generating the requested CSV file asynchronously. The export is returned with status created and is then processed in the background; poll it until its status is completed before requesting a download URL. (406 words) - [Get Export - Flex Documentation](/content/docs/api-reference/exports/get-export/index.html): Retrieves the details of an existing export, including its current status. Supply the unique export ID returned when the export was created. (286 words) - [Cancel Export - Flex Documentation](/content/docs/api-reference/exports/cancel-export/index.html): Cancels an export, setting its status to cancelled. An export that has already completed cannot be cancelled; an already-cancelled export is returned unchanged. (270 words) - [Get Payment Intent - Flex Documentation](/content/docs/api-reference/payment-intents/get-payment-intent/index.html): Retrieves the details of a PaymentIntent that has previously been created. (287 words) - [Get Payment Link - Flex Documentation](/content/docs/api-reference/payment-links/get-payment-link/index.html): Retrieves the details of an existing payment link, including its line items and applied discounts. If the link has no label yet, one is generated from its first line item's product and persisted before the link is returned. (342 words) - [List Exports - Flex Documentation](/content/docs/api-reference/exports/list-exports/index.html): Returns a list of your exports, sorted with the most recently created exports first. (370 words) - [List Payment Links - Flex Documentation](/content/docs/api-reference/payment-links/list-payment-links/index.html): Returns a list of your payment links. Only active links are returned; archived (inactive) links are omitted. Results are ordered by ID descending. Supports cursor pagination via starting_after/ending_before; offset is deprecated. Line items and discounts are not expanded here — retrieve a single link to load them. (345 words) - [Create Payment Link - Flex Documentation](/content/docs/api-reference/payment-links/create-payment-link/index.html): Creates a payment link: a shareable URL that generates a checkout session each time a customer opens it. The mode is determined by line_items — it becomes subscription if any price is recurring, otherwise payment; pass mode=setup to save a payment method without a charge (setup mode requires a label and empty line_items). Creating a link may create supporting objects as a side effect: inline price_data provisions a Product and Price (in Stripe and Flex), inline shipping rate data creates a Shipping Rate, and inline coupon_data discounts create Coupons. Promotion codes are not accepted as discounts here — use coupon IDs or inline coupon data. (408 words) - [Send Receipt - Flex Documentation](/content/docs/api-reference/payment-intents/send-receipt/index.html): Send a receipt to customer for the associated payment (243 words) - [Create Export Url - Flex Documentation](/content/docs/api-reference/exports/create-export-url/index.html): Generates a temporary, presigned URL for downloading the export's generated CSV file. The export must have a generated file available — typically once its status is completed. The returned URL expires after a short period, so request a fresh one when it lapses. (283 words) - [Cancel Payment Intent - Flex Documentation](/content/docs/api-reference/payment-intents/cancel-payment-intent/index.html): Cancels a PaymentIntent (287 words) - [Create or update a customer - Flex Documentation](/content/docs/api-reference/customers/create-or-update-a-customer/index.html): Creates a customer. This endpoint upserts by email: if a customer with the same email already exists, that customer is updated with the supplied values instead of a new one being created. A customer.created webhook event is fired only when a new customer is created (not on update). If checkout_session_id is provided, the referenced checkout session is updated to reference this customer. (393 words) - [List Promo Codes - Flex Documentation](/content/docs/api-reference/promo-codes/list-promo-codes/index.html): Returns a list of your promotion codes. Optionally filter by active. (325 words) - [Update a customer - Flex Documentation](/content/docs/api-reference/customers/update-a-customer/index.html): Updates the specified customer.

(526 words) - [List Disputes - Flex Documentation](/content/docs/api-reference/disputes/list-disputes/index.html): Returns a list of your disputes, most recent first.

(302 words) - [List Payment Intents - Flex Documentation](/content/docs/api-reference/payment-intents/list-payment-intents/index.html): Returns a list of payment intents (316 words) - [Update Payment Link - Flex Documentation](/content/docs/api-reference/payment-links/update-payment-link/index.html): Updates an existing payment link. Only the supplied fields are changed; omitted fields are left unchanged. The mutable fields are label, after_completion, and active — line items, discounts, and other parameters are fixed once the link is created. Set active to false to archive the link, which removes it from list results and makes checkout session generation from the link return a 404. Set active back to true to restore it. (363 words) - [Get Invoice - Flex Documentation](/content/docs/api-reference/invoices/get-invoice/index.html): Get an invoice by id (326 words) - [Get Dispute - Flex Documentation](/content/docs/api-reference/disputes/get-dispute/index.html): Retrieves the details of an existing dispute. Retrieves a dispute by ID, including its evidence, evidence submission details, payment method details, and associated balance transactions.

Supply product to attach the price to an existing product, or product_data to create a new product inline in the same request. A price is one-time unless you include recurring, in which case it bills on the given interval. Amounts are in the smallest currency unit (cents) and charged in USD. If HSA/FSA eligibility is not set on the price, the parent product's eligibility applies. (330 words) - [Retrieve a customer's payment method - Flex Documentation](/content/docs/api-reference/customers/retrieve-a-customers-payment-method/index.html): Retrieves a single payment method by ID for the specified customer. (310 words) - [Create Product - Flex Documentation](/content/docs/api-reference/products/create-product/index.html): Creates a new product. Flex automatically determines the product's HSA/FSA eligibility from the supplied name, description, identifiers, and URL; if it can't be resolved synchronously, the product is created with eligibility pending and classification continues in the background, after which a product.updated event may fire. A product.created event is sent to your configured webhook endpoints on success. (530 words) - [Retrieve a customer - Flex Documentation](/content/docs/api-reference/customers/retrieve-a-customer/index.html): Retrieves the details of one of your customers. (345 words) - [List a customer's payment methods - Flex Documentation](/content/docs/api-reference/customers/list-a-customers-payment-methods/index.html): Returns a list of payment methods attached to the specified customer, sorted by ID in descending order (most recently created first). (357 words) - [Delete a customer - Flex Documentation](/content/docs/api-reference/customers/delete-a-customer/index.html): Deletes the specified customer. This is a soft delete: the customer is marked as deleted and no longer appears in list or retrieve responses, but historical records that reference the customer (such as payment intents and checkout sessions) continue to resolve it. (237 words) - [Update Price - Flex Documentation](/content/docs/api-reference/prices/update-price/index.html): Updates the specified price by setting the values of the parameters passed. Any parameters not provided are left unchanged. Only description and active can be updated; the unit amount, currency, and recurring interval of a price are immutable. Setting active to false archives the price so it can no longer be used for new purchases. (483 words) - [List Payouts - Flex Documentation](/content/docs/api-reference/payouts/list-payouts/index.html): Returns a list of payouts. (305 words) - [Update Dispute - Flex Documentation](/content/docs/api-reference/disputes/update-dispute/index.html): Updates the evidence on a dispute, and optionally submits it to the card network. Saves the provided evidence fields, leaving any omitted fields unchanged; a file field sent as "" is cleared. File fields reference Flex file IDs that must have purpose dispute_evidence; they are resolved to the underlying card-network files before submission. When submit is true, the evidence is finalized and submitted to the network to contest the dispute — evidence cannot be edited after submission. The dispute must be in a needs_response or warning_needs_response status. (380 words) - [Count Disputes - Flex Documentation](/content/docs/api-reference/disputes/count-disputes/index.html): Returns the number of disputes that currently require a response. Counts disputes in a needs_response or warning_needs_response status. Useful for surfacing a "disputes needing action" badge without paging through the full list. (253 words) - [Processing Status - Flex Documentation](/content/docs/api-reference/products/processing-status/index.html): Returns how many of the account's products are still awaiting automatic HSA/FSA eligibility classification, capped for bounded cost on very large catalogs. Backs the dashboard "Syncing products" banner; clients derive any time estimate from pending_classification themselves. (252 words) - [Get Price - Flex Documentation](/content/docs/api-reference/prices/get-price/index.html): Retrieves the price with the given ID. Pass expand_product=true to inline the full Product object instead of just its ID. Resolves your own prices, and (if you belong to an organization) prices owned by a sibling account. (303 words) - [Mark Invoice Uncollectible - Flex Documentation](/content/docs/api-reference/invoices/mark-invoice-uncollectible/index.html): Mark an invoice as uncollectible. This will stop automatic collection attempts and move the associated subscription to an unpaid state. (259 words) - [Update Product - Flex Documentation](/content/docs/api-reference/products/update-product/index.html): Updates the specified product by setting the values of the parameters passed. Any parameters not provided will be left unchanged. Updates never re-run HSA/FSA eligibility determination — eligibility is set when the product is created and only changes through review. Passing categories replaces the product's existing categories (an empty array removes them all). A product.updated event is sent to your configured webhook endpoints on success. (557 words) - [List customers - Flex Documentation](/content/docs/api-reference/customers/list-customers/index.html): Returns a list of your customers, sorted by ID in descending order (most recently created first).

The rate is a fixed amount denominated in USD. New shipping rates are active by default. (439 words) - [Close Dispute - Flex Documentation](/content/docs/api-reference/disputes/close-dispute/index.html): Closes a dispute, accepting it as lost and forfeiting the disputed funds. Use this when you do not wish to contest the dispute. Closing is irreversible: it forfeits the disputed amount and the dispute fee, and no further evidence can be submitted. The dispute must be in a needs_response or warning_needs_response status. (247 words) - [Update Shipping Rate - Flex Documentation](/content/docs/api-reference/shipping-rates/update-shipping-rate/index.html): Updates the specified shipping rate. You can update active and metadata; both are overwritten with the values passed, and omitting metadata clears it. The shipping rate's display_name and amount are immutable. (438 words) - [List Prices - Flex Documentation](/content/docs/api-reference/prices/index.html): Returns a list of your prices, sorted by price ID in descending order (most recently created first). By default only active prices are returned; pass active=false to list archived ones, or filter to a single product with product. (419 words) - [Get Shipping Rate - Flex Documentation](/content/docs/api-reference/shipping-rates/get-shipping-rate/index.html): Retrieves the shipping rate with the given ID. (226 words) - [Create Coupon - Flex Documentation](/content/docs/api-reference/coupons/create-coupon/index.html): Creates a coupon. Exactly one of amount_off or percent_off must be provided; supplying both, or neither, is rejected. When duration is repeating, duration_in_months is required. (448 words) - [List Products - Flex Documentation](/content/docs/api-reference/products/index.html): Returns a list of your products, sorted by creation date with the most recently created products appearing first. By default only active products are returned; pass active=false to list archived ones. You can also filter by client_reference_id or by metadata using metadata[key]=value query parameters. (344 words) - [Retry Event - Flex Documentation](/content/docs/api-reference/events/retry-event/index.html): Redeliver an existing event to your webhook endpoints. The event is looked up by ID; a 404 is returned if no matching event exists. If a webhook_id is supplied in the body, the original event is redelivered to that specific webhook endpoint and the stored event is returned. If no body is supplied, the event is redelivered to all of your configured webhook endpoints; in this mode only checkout.session.completed events are supported — the checkout session is re-fetched with its related objects expanded and a new event (with a fresh fevt_ id) is generated and delivered. (371 words) - [Get Coupon - Flex Documentation](/content/docs/api-reference/coupons/get-coupon/index.html): Retrieves a coupon by its ID.
