one_code_per_customer

This organisation already has an affiliate code.

HTTP 409.

Likely cause: The organisation came through an affiliate’s link or code, and another code was typed.

What to do: Check out without the second code. The first one still applies (applied_code).

Retry: No. The same request gets the same answer; change something first.
