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, 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, connection acceptances, and more.
