Authentication

The ThredUp API uses API keys to authenticate requests. You can request your API key from your ThredUp representative.

Tip

API requests must be submitted with a valid API key over HTTPS. Requests submitted over plain HTTP or without a valid API key will fail.

Warning

Your API keys grant extensive access, so it’s important to keep them secure. Avoid exposing secret keys in publicly accessible places such as GitHub repositories or client-side code.
