HTTP 409 Not retryable

What to do

Use the original binding target on a retry. Bind a provisional signup before attaching outcomes, enforcements or issued keys. This route does not merge arbitrary accounts.

In the SDKs

The Node and Python SDKs raise ConflictError. The Go SDK returns *apierrors.ConflictError, which you match with errors.As.
