Send synthetic test events to verify webhook subscription configuration and endpoint availability.
What this does:

• Generates test events: Creates synthetic events for all event types in the subscription
• Sends webhooks: Delivers test webhooks to the configured callback URL
• Returns event IDs: Provides unique identifiers to track and verify test deliveries
• Validates endpoint: Tests that your webhook endpoint can receive and process events

Testing workflow:

1. Trigger: Call this endpoint to send test events
2. Track: Use returned eventIds to monitor delivery status
3. Verify: Check your endpoint received the webhooks correctly
4. Debug: Use delivery records to troubleshoot issues

Test event characteristics:

• Contains sample data structure matching real events
• Includes metadata indicating it's a test event
• Follows same delivery flow as production webhooks
• Can be verified using the delivery verification endpoint

Common use cases:

• Integration testing: Verify your webhook handler works correctly
• Endpoint validation: Confirm callback URL is accessible and responds properly
• Development: Test changes without waiting for real events
• Monitoring: Verify subscription is active and functioning

Important notes:

• Test events are clearly marked as synthetic/test data
• Delivery records expire after 7 days (TTL)
• Use eventIds with GET /synthetic-delivery to verify delivery status
• Does not affect production event delivery or subscription configuration
