Idempotency

Idempotency (platform contract)#

Phase C: BPN does not yet standardize an Idempotency-Key header.
Merchants must use business fields below. Treat this table as a stable contract.

Key map#

Retry rules (hard)#

1.
Timeout / unknown outcome: retry with the same idempotency key (exponential backoff).
2.
Clear validation failure: fix params, then use a new key.
3.
In-flight processing: do not change the key; poll detail or wait for webhook.
4.
Terminal success / fail: do not retry the same key expecting a different outcome.

Type conventions#

TypeRule
AmountsDecimal string (e.g. "100.50"), never JSON float
TimestampsEpoch milliseconds integer
