The Autopay Bacs API allows you to:

• Create payment files, add instructions, and delete instructions.
• Create payment file templates, and complete and approve payment files.
• Retrieve the results of manually importing a payment file, including querying by status, file type or a specified date range.
• List, view, export, mark as downloaded, and update the status of Bacs messages.

API clients

OAuth2 is used to authenticate API access for integration with Autopay Online Plus.

API clients can be managed directly from the user interface, including creating new clients and generating client ID and secret. Once an API client has been created, you can generate an access token. This token is then used to authenticate and make API calls.
