A workflow verifies its write by tying the approved payload to one request identity, preserving the destination response, reading the object back, and recording any difference for reconciliation.
Make repeated writes safe
A successful HTTP response proves that a destination accepted a request, but it does not always prove that the intended object now contains the intended values. Retries can create duplicates, server-side defaults can change fields, and concurrent work can overwrite a recent update. The workflow therefore needs both a write receipt and a check against the resulting state.
Idempotency gives repeated attempts one identity. Stripe documents this pattern for API requests: a client sends an idempotency key so a retry can return the prior result instead of repeating the operation. Other systems use upserts, unique external identifiers, or conditional writes. The adapter should use the strongest mechanism the destination supports and document its limits.
Verify the destination state
The posting record should include the approved payload hash, request identifier, destination endpoint, time, response status, and created or updated object identifier. Secrets and sensitive fields should be redacted according to buyer rules. A failure should remain attached to the same case so an operator can retry without rebuilding the source and review history.
A read-after-write step fetches the destination object and compares the agreed fields with the approved payload. The comparison should account for documented server transformations, such as normalized timestamps or generated identifiers, while treating unexpected differences as exceptions. The accepted comparison becomes the reconciliation receipt for that case.
Reconcile failures without erasing their history
Batch reconciliation then accounts for every input. Each case should be posted, held, rejected, or failed with a reason. Totals should reconcile across those states, and duplicate source identifiers should be visible. A dashboard that reports only successful writes can hide the records that disappeared before the adapter ran.
Reality Contact, LLC can implement and test the adapter, receipts, and reconciliation logic. The buyer supplies authorized access, approves the mapping and retry behavior, and decides when a failed case may be replayed. Production writes begin only after the supervised test set passes the buyer's acceptance rules.
Where the service stops
Reality Contact, LLC implements and tests the technical workflow using buyer-authorized systems, but does not choose business policy, approve consequential decisions, supply production credentials, or authorize writes on the buyer's behalf. The buyer approves the mappings, review rules, access, retention terms, and test results, then processes a bounded live batch through the supervised workflow. This is technical implementation based on buyer-supplied rules and authorized access, and it does not replace legal, financial, security, privacy, or professional advice. The buyer controls credentials, source rights, business rules, retention decisions, reviewer authority, and every production release.
