Admission limits bound external requests independently from price. A managed call can fail for insufficient credit (402) or for an admission ceiling (429); the two conditions are not interchangeable.
Application limits
GET and PUT /v1/applications/{appId}/limits control:
| Field | Accepted range |
|---|---|
dailyProviderRequests |
1–100,000 |
providerRequestsPerMinute |
1–600 |
activeServiceInvocations |
1–100 |
Each saved service connection also has a positive dailyLimit. The stricter applicable ceiling wins.
Reuse and idempotency
Read operations with the same application, credential version, and normalized input may reuse a successful call for five minutes. Write operations reuse only the identical idempotency identity.
UNKNOWN outcomes
An ambiguous provider outcome is recorded as UNKNOWN and is never automatically resubmitted. Managed credit remains reserved. Owners review GET /service-reconciliations and post either settle or release to the specific reconciliation ID.
