Citigroup Rate Limits

An exhausted limit returns HTTP 429.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Policies

Backoff Strategy
Clients should implement exponential backoff with jitter on HTTP 429/503 responses and honor any Retry-After header.
Partner provisioning
Higher production limits are configured per partner agreement and may require Citi relationship-manager approval and security review.
OAuth 2.0 token handling
Reuse access tokens until expiry; do not re-issue tokens per request, which would consume Authorization-Server rate budget.
