Request design
- Define explicit request schema and required variables before wiring API nodes.
- Set deterministic headers and auth binding from connection profiles only.
- Use idempotency keys for write operations that can be retried.
Integrations
API Node and Webhooks Guide
Implement robust API actions and webhook handling with retries, idempotency, and failure containment.

Response handling
- Map success and error responses to separate branches with user-safe messaging.
- Normalize provider-specific fields into internal variable conventions.
- Guard against partial responses and missing fields with defaults.
Webhook operations
- Validate signatures and reject untrusted sources before processing payloads.
- Acknowledge quickly, then process asynchronously when workloads are heavy.
- Track delivery failures and replay safely using idempotent processing keys.
Operational Checklist
- OKRequest/response contracts are documented.
- OKIdempotency is implemented for mutating operations.
- OKWebhook signature validation is active.
- OKError branches are tested with real failure payloads.
