CRM Integration via API.This is a reverse integration: the CRM sends an HTTP request to a specified URL when an event occurs. For example, when a deal's status changes, the CRM sends a JSON payload to your service. Webhooks are handy for notifications and automated reactions: sending an SMS to a customer, creating a delivery, generating a document.Simple integration; near-real-time notifications; no polling required; low latency; loose coupling.No delivery guarantee without retries; a public endpoint and signature verification are required; duplicates and out-of-order delivery are possible; idempotency and deduplication are needed; rare failures are harder to debug.
