Limits

Per-Merchant Capacity merchant
varies
see merchant agreement / developer portal API reference
Heartland does not publish numeric per-API throttle ceilings. Card-network and processor-side controls (issuer, scheme, fraud) apply in addition to any platform throttle.

Policies

Backoff Strategy
Implement exponential backoff with jitter on 5xx and any 429-class responses; honor Retry-After when present.
Idempotency
Use the Portico Gateway's documented idempotency mechanisms (e.g. ClientTransactionId) to avoid duplicate authorizations on retry.
PCI Scope
Limit retries on PCI-scoped endpoints to avoid expanding cardholder-data exposure.
Capacity Uplift
Higher sustained throughput is provisioned by the Heartland implementation team during merchant onboarding.
