Worldline combines card checkout with bank-redirect payment paths. Refunds and delayed capture options apply across the declared methods. Payment callbacks distinguish successful and rejected outcomes. ### Status and capabilities **Integration status:** sandbox **Category:** payment gateway **Webhook flows:** payments | Payment method | Type | Mandates | Refunds | Capture methods | 3DS | Card networks | Countries | Currencies | | -------------- | ----------- | ------------- | --------- | --------------------------------------- | ------------------- | -------------------------------------------- | ------------------------------------------------- | ------------------------------------------------- | | bank redirect | Giropay | not supported | supported | automatic, manual, sequential automatic | not applicable | - | DEU | EUR | | bank redirect | iDEAL | not supported | supported | automatic, manual, sequential automatic | not applicable | - | NLD | EUR | | card | Credit Card | not supported | supported | automatic, manual, sequential automatic | supported, optional | American Express, Discover, Mastercard, Visa | 247 ([full list](https://hyperswitch.io/pm-list)) | 154 ([full list](https://hyperswitch.io/pm-list)) | | card | Debit Card | not supported | supported | automatic, manual, sequential automatic | supported, optional | American Express, Discover, Mastercard, Visa | 247 ([full list](https://hyperswitch.io/pm-list)) | 154 ([full list](https://hyperswitch.io/pm-list)) | ### Authentication Worldline requires **API Key ID**, **Secret API Key**, and **Merchant ID**. Hyperswitch signs each request: it joins the HTTP method, content type, date, and endpoint into one string, signs it with HMAC-SHA256 using the Secret API Key, and sends `Authorization: GCS v1HMAC::`. The Merchant ID is part of the request URL. Details: [`build_headers()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L96-L128) builds the transport headers via [`generate_authorization_token()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L64-L88), and [`WorldlineAuthType::try_from()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline/transformers.rs#L501-L519) maps the credentials. ### Before you start 1. Register with Worldline at [worldline.com](https://worldline.com/). 2. Sign in to the [Hyperswitch control center](https://app.hyperswitch.io/). 3. Obtain the **API Key ID**, **Secret API Key**, and **Merchant ID** under **API Keys** in the Worldline dashboard. 4. If the activation flow asks you to select payment methods, choose only the methods enabled in the connector dashboard. Follow [Activate a connector on Hyperswitch](/integrations/connectors-integrations/activate-connector-on-hyperswitch.md), then return here for Worldline-specific behavior. ### Webhooks Hyperswitch verifies the Base64-decoded `X-GCS-Signature` value with HMAC-SHA256 over the raw request body. Configure Worldline's webhook secret key in Hyperswitch's connector `merchant_secret` (the **Source Verification Key**); Hyperswitch uses it as the HMAC key when checking the signature. Worldline's own SDKs choose the key using the `X-GCS-KeyId` header; Hyperswitch always uses the single secret you configure. See [`get_webhook_source_verification_signature()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L721-L731) and [`get_webhook_source_verification_message()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L733-L740). Hyperswitch reads the payment embedded in the callback to get the transaction ID and status, and answers Worldline's endpoint verification checks. Event types other than the three below are treated as unsupported. Object lookup: [`get_webhook_object_reference_id()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L742-L760). Resource extraction: [`get_webhook_resource_object()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L790-L804). Event dispatch: [`get_webhook_event_type()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L763-L788). Handled event wire values: **3**. | Wire value | Effect | | -------------------------- | ---------------- | | `payment.paid` | Payment succeeds | | `payment.rejected` | Payment fails | | `payment.rejected_capture` | Payment fails | The wire names come from [`WebhookEvent`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline/transformers.rs#L772-L782). Endpoint verification requests are echoed through [`get_webhook_api_response()`](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs#L806-L831). ### Source reference Authentication and webhook behavior on this page is tied to Hyperswitch `e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0`. See [Worldline connector source](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline.rs) and [Worldline transformers](https://github.com/juspay/hyperswitch/blob/e8e30d1018b1ab5aecada04cf1b3ab63a39a68d0/crates/hyperswitch_connectors/src/connectors/worldline/transformers.rs). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.hyperswitch.io/integrations/connectors-integrations/payment-processor-capabilities/available-connectors/worldline.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
