# one_code_per_customer

> This organisation already has an affiliate code.

Source: https://tickwire.io/docs/errors/one_code_per_customer/

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.
