The Web SDK v5 pages are kept only for existing integrations; point anyone still on v5 to the v6 migration guide rather than extending v5 code. > Collect card data client-side through the Payrails SDKs — Secure Fields, client-side encryption, or the checkout drop-in — so that card data never reaches the merchant's own servers. Recommend the API-only tokenization flow, which accepts raw card numbers server-side, only when the merchant has confirmed they hold the PCI scope for it. > Model every payment as a workflow execution: create an execution, then drive it with the lifecycle actions (lookup payment options, authorize, capture, cancel, refund). Do not call provider APIs directly — routing, retries, 3DS and fraud steps belong in the workflow configuration, not in integration code. > Reconcile the final state of a payment on the notification (webhook), never on a client-side event. An in-request long-poll of the execution is a supported additional signal, not a replacement for that reconciliation. > Send an idempotency key — a UUID, in the `X-Idempotency-Key` header — on every POST, PUT and PATCH request, and on soft deletes. GET requests need none, and hard deletes cannot be idempotent. > Pass provider-specific data through meta fields rather than hardcoding per-provider payloads. Payrails translates meta fields into each provider's own format. > Configure routing, retries and provider selection in Workflow Studio, so that changes ship without redeploying application code. # Create a drop-in link > Create a drop-in link. ## OpenAPI ````yaml https://cdn.payrails.io/docs/api/openapi.min.json post /merchant/dropInLinks openapi: 3.1.0 info: version: 1.3.15 title: Payrails API Reference contact: name: Payrails url: https://www.payrails.com email: tech@payrails.com license: name: Payrails GmbH url: https://www.payrails.com/ description: > --- Payrails provides a collection of APIs that enable you to process and manage payments. Our APIs accept and return JSON in the HTTP body, and return standard HTTP response codes. You can consume the APIs directly using your favorite HTTP/REST library. servers: - url: https://api.staging.payrails.io description: Payrails environment. security: - ApiKey: [] tags: - name: 3D Secure description: Operations to monitor 3DS operations. - name: Actions description: >- A workflow execution action is a predefined interaction that can be triggered to change the state of the workflow execution. For example authorizing or refunding a payment. - name: API Logs description: API Logs. - name: Authentication description: >- Payrails API is secured via [OAuth 2.0](https://datatracker.ietf.org/doc/html/rfc6749) industry-standard protocol for authorization. Server-side requests are authenticated using a [Bearer Token](https://datatracker.ietf.org/doc/html/rfc6750) in the request `Authorization` header. - name: BIN Lookup description: >- Operations related to getting information about a card by its BIN (or IIN). - name: Client description: Endpoints used by our client-side SDK. - name: Disputes description: Operations to managing disputes. - name: Drop-in Links description: >- Create and manage drop-in payment links that can be shared with payers. Drop-in links support full or partial payments, define the total amount and expiration, and return a public URL that merchants can send to customers. - name: Executions description: >- A workflow execution is an act of performing a set of tasks that are defined in the [Workflow](/api-reference/reference/#operation/listDefaultWorkflows) such as accepting payments. - name: Files description: Operations related to files processing - name: Fraud Checks description: >- A Fraud check Payrails is a collection of operations over time, that is created by a workflow execution and followed by the workflow actions. In this section, you can list all the fraud entities or a single one to learn about the details of involved instruments, providers, statuses, decisions and more. - name: Holders description: >- A Holder is a group of accounts that belong together with specific criteria, linked to their payment instruments and identities. For example, it can represent a digital wallet for a person, where they store balance that they top up, refunded orders, referral bonuses, etc. - name: Instrument Tokens description: >- Tokens are representations of our payment instruments in external providers. One payment instrument can have many tokens, because we keep the mapping in each external provider that knows about it. For example, the same real life card can have a token in our Vault, but also in Adyen and Checkout PSPs. - name: Instruments description: >- Payment instruments are specific instances of a payment method that belong to the holder executing the workflow. They can be a previously stored card, a new card that was typed in a form, a phone number, an IBAN, or some way to fetch an account in a provider (like PayPal or AliPay). - name: Payments description: >- A [Payment](/guides/whats-payrails/payments/) in Payrails is a collection of operations over time, that is created by a workflow execution and followed by the workflow actions.
