This API enables you to Accept transactions for your Merchant customers.

Transactions are accepted via a host-to-host connection between the API user and Worldline FS API Gateway. The Worldline FS API Gateway is connected to the Worldline FS acceptance host, which in turn is connected to the Issuer network.

Version note:

Please be aware that these API interfaces may be changed and improved (e.g. addition of fields).

The WL FS Sandbox for Accept Transactions API is available on request for PSPs and banks integrating with Worldline Financial Services (equensWorldline).

Latest open API spec below includes drop-down examples of requests (e.g. Purchase VISA Authorization) and drop-down examples of successful "200" responses. The “Try Out” button functionality is currently not available.

Accept Transactions API version 1.0.2 is operational for Card Not Present transactions. The API roadmap for 2025 includes (Soft-)POS transaction acceptance via this API.
