How authentication works

External endpoints are protected by an API key that must be sent in the Authorization header using the Basic scheme. The value after Basic must be a Base64-encoded credential string. The credential string is: <client_id>:<api_key>. Where:
  • client_id is your assigned client name or identifier.
  • api_key is your secret key.

​
Request format

  1. Build the credential string: <client_id>:<api_key>.
  2. Base64-encode the credential string.
  3. Send it in the Authorization header using Basic.

​
Example

curl -H "Authorization: Basic <base64(client_id:api_key)>" \
