pre-conversation

Fired **before** the agent begins speaking. Use this to enrich CRM data, log call attempts, or gate outbound calls. Does **not** contain `callData`, `transcript`, `variables`, `analytics`, or `recordingUrl`. `callData` is on `post-conversation` and `analytics-completed`; `transcript`, `variables`, and `recordingUrl` are only on `post-conversation`; `analytics` is only on `analytics-completed`. **Delivery.** Sent as an HTTP POST with a 30 second timeout. Non-2xx responses and network errors mark the delivery as failed; there are no retries. Verify the `X-Signature` header before trusting the body.
