Authentication
Authenticate with an access token from the identity provider’s token endpoint (grant_type=client_credentials, scopes partner/<scope>) in the Authorization header. See Authentication.
Rate limit headers
Every authenticated answer carriesX-RateLimit-Limit and X-RateLimit-Remaining, the partner’s daily allowance and what is left of it. A 401, and a path or method outside this API, carry neither. Past the allowance the API answers 429 rate_limited with Retry-After. See Rate limits.
Errors
Errors use one shared envelope with a stablecode, a safe message, a correlation_id and an optional reason. See Errors.
