The La Growth Machine API: build your outbound into anything.
A REST API to read and drive your workspace from your own code: campaigns and stats, audiences, leads, enrichment, LinkedIn and email messages, your inbox, and real-time webhooks.
Available from the Pro plan
The same API behind our own integrations.
Our n8n node, our MCP server for Claude and ChatGPT, and our website visitor webhooks all run on this API. Whatever they do, your code can do too.
Push leads in
From your product, your forms or your data warehouse, straight into an audience.
Pull results out
Campaign stats, lead logs and conversations for your own reporting.
Build agents
Read the inbox, draft a reply, send it on LinkedIn or email.
Drive campaigns
Update settings, pause and resume, change lead statuses.
Simple to call, easy to debug
One base URL, one API key, JSON in and out. Pass the key as a bearer token, and test it with a single call to list your workspace members.
Every call shows up in your API logs, with the endpoint, the status, a summary of the result and the time. Filter on failed requests to find what went wrong.
