Plan a 4All API or Webhook Integration

Define use case, entitlement, authentication, events, payload contract, security, retries, and ownership.

Design an enterprise integration that is authorized, observable, idempotent, and safe to operate before any production credential is issued.

Best for: Enterprise architects, developers, security reviewers, and 4All solution engineers.

Before you start

API access and webhooks are plan entitlements; the codebase models API, webhooks, and BYOK as enterprise capabilities.

  • Use the current production release and approved organizational policy.

  • Record resource IDs, exact time zone, and accountable owner.

  • Validate in a non-production environment when possible.

  • Obtain written use case, data classification, systems, environments, volume, and support owner.

  • Confirm API/webhook entitlement and current official contract with 4All.

  • Create separate development and production endpoints/credentials.

Planning guide

  1. Define the business event and minimum data required; avoid subscribing to more participant/transcript data than needed.

  2. Document direction: polling/API request, outgoing webhook, or desktop endpoint; identify authoritative system.

  3. Select an approved authentication method and secrets manager; define rotation and revocation.

  4. For webhooks, require HTTPS, verify signatures against the raw request, reject stale/replayed delivery, and store the event/delivery ID for idempotency.

  5. Return success quickly and process asynchronously; use bounded retry with exponential backoff and dead-letter handling.

  6. Version the schema and tolerate additive fields; validate required types and reject malformed data safely.

  7. Add correlation IDs, redacted logs, metrics, alarms, replay controls, and a runbook.

  8. Complete security/privacy review, load/failure testing, and a cutover/rollback plan before production.

What success looks like: The integration has an approved contract, entitlement, threat model, test evidence, owner, monitoring, and rollback.

Check your setup

  • No secret is in source code or tickets.

  • Duplicate delivery is harmless.

  • Signature/replay checks are tested.

  • Production and test data are separated.

Troubleshooting

  • 401/403: verify entitlement, identity, scope, and environment.

  • Duplicate side effects: fix idempotency before re-enabling.

  • Webhook timeout: acknowledge then queue work.

  • Schema change breaks parser: tolerate additive fields and pin contract version.

Security and operational notes

Important: Do not infer or scrape undocumented endpoints. Use the current official 4All enterprise API/webhook contract and least-data access.
