Store the Sendora API key in the platform’s secret or credential store. Configure the base URL as https://api.sendora.ai and send the key as X-API-Key; never put it in a query parameter or browser-visible field.

​
Safe automation pattern

Use preview endpoints for prospecting, preflight for campaigns, and draft states for voice agents. Keep production sends and calls behind an explicit approval step.

​
Retries

Configure retries only for 429 and transient 5xx responses. Honor Retry-After, use exponential backoff with jitter, and reuse an idempotency key when the endpoint supports one. Never automatically retry a launch, message, call, publish, plan change, or delete after an unknown timeout.

​
Webhook-to-worker pattern

Verify the raw-body signature, deduplicate the event or delivery in durable storage, enqueue the work, and return 2xx quickly. Keep the webhook handler independent from long-running enrichment, CRM, or analytics work.
