Citigroup Rate Limits

Citi APIs (Citi Developer Hub, CitiConnect, Citi Velocity) enforce rate limits at the application / partner level. Public quantitative thresholds are not published in self-serve form; limits are negotiated and documented inside the partner agreement and developer portal once production access is provisioned.

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.
