Huntington Bancshares Rate Limits
Huntington's developer portal does not publish numeric rate limits. The platform is built on Apigee X and Apigee enforces per-API-product quota and spike-arrest policies that are configured per partner contract. Quotas are issued per OAuth client / consumer key based on the treasury management agreement. The platform is sized for 10M+ transaction events daily across the customer base.

Limits
Treasury Management API (per partner) oauth_client
not publicly published; negotiated per Apigee API product
Apigee quota policies enforce per-product per-minute and per-day caps.
Spike arrest oauth_client
not publicly published; Apigee spike-arrest policy
Burst protection independent of quota; smooths inbound traffic.
Policies
OAuth2 / mTLS Authentication
All production calls require an OAuth2 client credentials flow plus typically mTLS for treasury-grade endpoints. Tokens are short-lived.
Apigee Quota Enforcement
Per-consumer-key quota and spike-arrest policies enforce both burst and sustained ceilings. Specific values are configured per partner per API product.
429 Throttling Response
Standard Apigee 429 response with Retry-After header when quotas are exceeded.
Backoff Strategy
Implement exponential backoff and honor Retry-After header. Coordinate with Huntington partner enablement on quota raises.
Sandbox vs Production
Sandbox endpoints have separate, lower limits intended for integration testing only.
