Developer documentation

Everything Alync finds is available over a versioned REST API, signed webhooks, and an MCP server for AI assistants. API access is available on the Scale plan and above.

REST API

Authenticate with an API key and drive campaigns, leads, and enrichment programmatically. OpenAPI spec included.

Webhooks

Get signed HTTP deliveries the moment leads are promoted or enrichment finishes — the backbone of every integration.

MCP — Claude & ChatGPT

Add Alync as a connector so an AI assistant can create campaigns, run sourcing, and read leads in chat.

n8n

Self-hosted automation: trigger workflows from Alync webhooks and call the API with the HTTP Request node.

Make (Integromat)

Build scenarios on Alync events with custom webhooks and HTTP modules.

Zapier

Connect Alync to 6,000+ apps using Webhooks by Zapier.

The 5-minute version

Create an API key in the app: Settings → API Keys (Scale plan and above).

Call the API with the key in a header:

curl https://api.alync.co/v1/campaigns \
  -H "X-API-Key: alync_live_..."

Subscribe to events with a webhook channel — you’ll receive signed JSON deliveries for lead_promoted, enrichment_finished, campaign_finished, and more.

The machine-readable spec lives at https://api.alync.co/v1/openapi.yaml.
