Run provider operations safely through the gateway ​

Purpose ​

Applications perform provider operations through a recorded call with safeguards against unsafe repetition.

How It Works ​

An application submits a contract-shaped request to the gateway. The gateway authorizes the caller, selects a connection and records the operation. It uses the execution as the continuing identity across safe attempts. Existing-key requests return the existing state or answer instead of creating another provider operation. Admission can hold a provider off before delivery. Failures are classified before deciding whether to wait, retry or investigate. Queued work continues non-sensitive operations that cannot finish immediately. Optional payload records support diagnosis where the contract permits them. The product should keep retry controls subordinate to whether the original operation may already have happened.

Relationships ​

  • Requires explain and select the connection for a call to supply the prerequisite configuration or operation.
  • Requires protect credentials throughout their useful life to supply the prerequisite configuration or operation.
  • Connects with determine the result of uncertain or overdue calls through shared integration records.
  • Connects with inspect calls and resolve operational problems through shared integration records.

The Formal Contract

The narrative above explains; the sections below are authoritative — the rules, scenarios and tests this document binds.

Outcomes
Call history includes the execution, its attempts and selected binding.Repeated identical requests reuse the existing result.Admission controls protect providers and stop payments that cannot run within their budget.

Before recording an execution, the gateway rejects requests over one megabyte, contract violations, unsupported modes, missing required idempotency keys, keys with surrounding whitespace and excessive timeout requests.
