Define the integration contract

Notify reviewers about pending tasks while keeping the decision and sensitive details inside the authenticated review system.

Contract item Design decision
Source event key review task ID + version
Destination outcome internal notification
Record ownership The source system owns its authoritative business fields.
Delivery model Assume duplicates and delayed or out-of-order events until proven otherwise.
Live readiness Authenticate, sandbox-test, approve data handling, and assign an operator.

Map the fields

Source Destination Validation
review_id task_link Authenticated review destination
category alert_category Safe summary only
owner_id reviewer_reference Authorized role
expires_at approval_expiry Reject stale decisions
version decision_version Approval bound to content version

Implement the handoff

  • Create a least-privilege connection using the vendor’s supported authentication method. Keep secrets in the workflow credential store.
  • Receive and authenticate the event using current vendor guidance. Save a bounded job record, then process asynchronously where the provider’s acknowledgement deadline requires it.
  • Look up the tenant, source record, and mapping. If any identifier is ambiguous, create a review task instead of guessing.
  • Apply a durable duplicate-prevention key. Read the destination before retrying an action whose result is unknown.
  • Write the approved result and reconcile it against the expected business state. Record safe metadata and a reviewable outcome.

Failure and recovery checks

Failure Expected response
401 / expired authorization Stop this connection, alert its owner, and reauthorize through the approved process.
429 / rate limit Respect provider retry guidance and use a bounded backoff queue.
Invalid field or mapping Quarantine for correction; do not endlessly retry a bad payload.
Timeout after write Check the destination using the stable reference before repeating the action.
Missed events Run an approved periodic reconciliation against the source.

Test these integration-specific cases

  • A Slack message click alone is not an approval.
  • An expired or replayed decision must be rejected.
  • A changed draft must require a new review.

The starter files demonstrate transformation and review behavior with synthetic data. They do not include live credentials or pre-authorized vendor accounts. Confirm current API schemas, plan entitlements, region, pagination, and webhook verification in the vendor documentation before connecting a firm.
