Every “Create Gateway” or “Edit Gateway” form has a “API URL” field that contains a URL that shall be set in the gateway as a page address that the gateway shall post to.

The API URL depends on the B3 address and the gateway type.

Use “Copy” icon on the right to copy the URL to clipboard and then enter it as a POST address in the gateway settings.
