All requests to the API require you to authenticate using HTTP basic authentication.

During the integration process, RepSpark provides you with a client key UUID for your brand and environment key UUIDs for the development, UAT, and production environments. The client key acts as the username, while the environment key serves as the password in the basic authentication system.

To make test requests that don’t affect live data, use the dummy client key along with any environment key. The dummy client key is 00000000-1111-2222-3333-444444444444.

The Authorization header is constructed as follows:

The client key and environment key are joined by a single colon: CLIENT_KEY:ENVIRONMENT_KEY
The resulting string is then encoded using Base64 and appended to Basic in the following format: Authorization: Basic BASE64_ENCODED_STRING
