Register as an API caller to make calls to the API.
Your registration token (rsu_api_reg) and password (X-RSU-API-REG-SECRET) can be included in any API request and are tied to your user account.
By registering your API usage, we can contact you if there are upcoming changes to be aware of or if we notice an issue with the API calls that you are making.
For partners, follow this link for your partner API key.
For affiliates, click the "API Access" link in your affiliate menu.
Your partner or affiliate API keys should be sent in the rsu_api_key GET parameter and X-RSU-API-SECRET HTTP header (or api_key and api_secret GET parameters for legacy API keys) in API calls.
See the OAuth2 Developer Guide for detailed registration and implementation information.
