Developer Documentation
Integrate Weezly Outreach with your existing tools and workflows. Receive real-time event notifications via webhooks or interact with your data through the REST API.
Webhooks
Receive HTTP callbacks when events happen: replies, AI-detected interested leads, connections, campaign completions, and more.
REST API
Programmatically manage leads, campaigns, accounts, and pipeline with full CRUD operations.
Core Concepts
Authentication
All API requests require your API key in the X-API-KEY header. Webhook payloads are signed with HMAC-SHA256 using your webhook secret, sent in the X-Webhook-Signature header.
Event-Driven Architecture
Weezly Outreach uses an event-driven architecture. Webhooks fire in real-time as actions occur, no polling required. Events include campaign step completions, lead replies, AI-detected interested leads, connection acceptances, and more.
