Connections

Connections materialize the individual link between a user and a connector. They act as a parent for business data and hold metadata about the synchronization state, the PSU credentials and consents.

API endpoints
Authentication: endpoints listed in this page require header authentication with a user token.

/webauth
Redirect to a URL for web authorization
To optimize user experience, the URL should be opened in a fully-capable browser. From a website or webapp, perform a full-page redirect. In a native Android app, prefer opening the default browser or relying on Chrome Custom Tabs. In a native iOS app, prefer using a SFSafariViewController.
After the flow has terminated, a redirection will be performed to the provided redirect_uri, with additional query parameters:
