Why do my users' connections keep disappearing on their own?

Check your own backend first: a call to /auth/deauthenticateUser removes the connection straight away, even if the user didn't ask to disconnect.

Check your own backend first. A call to DELETE /auth/deauthenticateUser removes the connection straight away and sends a deauth webhook for that user ID, whoever triggered it in your stack.

Connections that disappear repeatedly for users who say they didn't disconnect have been traced to the customer's own app, for example:

• a disconnect button or settings flow that fires when the user didn't mean to disconnect

• a cleanup job that deauthenticates users who are still active

How to confirm it:

• Log every call your backend makes to /auth/deauthenticateUser, with the user_id and what triggered it.

• Match those calls against the deauth webhooks you receive for the affected users.

When the user reconnects, they get a new user ID in the auth webhook. Because the old connection was already removed, there is no user_reauth linking the two, so key your records on your stable reference_id. See how do I handle a changed Terra user ID after reauth.
