Account linking response code change

Starting no sooner than April 13, 2025, Ory Network will return a 400 Bad Request instead of a 200 OK when a user signs up with Social Sign-In for an account that already exists. The associated error message has ID 1010016 and states:

You tried to sign in with %q, but that email is already used by another account. Sign in to your account with one of the options below to add your account %[1]q at %q as another way to sign in.

Previous behavior​

When signing up using the OIDC strategy and sending Accept: application/json in the request, Ory Network returned a 200 OK response even if an account with the same email address already existed.

New behavior​

Ory Network will now return a 400 Bad Request response in the same scenario.

Action required​

  • Ensure that your application can handle a 400 Bad Request response when signing up with Social Sign-In for an existing account.
  • If you have questions or concerns, contact us via Zendesk, Slack, or email at [email protected].
