Send data from any external tool (Zapier, Clay, RB2B, your own app, etc.) into Duo Copilot via a webhook. Whenever new data arrives, Duo generates a signal and can automatically create personalized sequences for each lead.
This endpoint uses a token-based URL instead of the standard API key authentication. Each custom signal has a unique token embedded in its webhook URL. You can find your token in the Duo Copilot signal settings.
Treat your webhook URL as a secret — anyone with the URL can send data to it. Avoid sharing it
publicly or committing it to repositories.
The request body is a dynamic JSON object. You can send any fields that are relevant to your use case — there is no fixed schema.After sending a test request, Amplemarket will auto-map your fields to the identifiers it needs to look up each person or company.
Test data vs. live data: During initial signal setup, requests are treated as test data for
configuring field mappings — no leads are generated. Once the signal is saved, all subsequent
requests generate real leads.
