Custom Webhook + La Growth Machine: connect any tool, in both directions.
Send lead data out of your sequences at the exact step you choose, push leads in from any tool, and stream every LinkedIn and email message to your own endpoint in real time.
API and webhooks available from the Pro plan
No native integration for your tool? You don't need one.
A webhook is a URL. If your tool can receive one or call one, it can talk to La Growth Machine: Zapier, Make, n8n, your CRM, your data warehouse, your own backend.
Out, from a sequence
A Webhook step sends the lead's data and a custom status when they reach it.
In, to an audience
Any tool adds leads to an audience, and they enter the running campaign.
Out, in real time
Inbox webhooks post every LinkedIn and email message to your URL.
Trigger your tools from any step of a sequence
Register a URL once in Settings, Webhooks, then drop a Webhook step anywhere in your sequence, on the no-reply branch for example. When a lead reaches it, La Growth Machine sends their info and the status you wrote, like "It's time to call the lead!".
The lead keeps moving through the sequence. You can also fire a webhook from a custom exit, the moment a lead replies.
What teams do with it expand_more
- Create a call task in HubSpot or Aircall when a lead hasn't replied
- Push the lead's status to Salesforce or any CRM
- Add engaged leads to Facebook or LinkedIn custom audiences
- Log stats in Google Sheets
- On reply: create a deal, notify Slack, open a qualification task
Push leads in from anywhere
A signup, a form, a product event: send it to La Growth Machine with your API key and the name of an audience. A LinkedIn URL, an email, or a name and company is enough. Leads added to a campaign's audience enter the running sequence automatically.
Using RB2B or Warmly? Paste the ready-made website visitor URL in their settings. No code at all.
The request expand_more
POST https://apiv2.lagrowthmachine.com/flow/leads with an audience name and at least one identifier: LinkedIn URL, pro or personal email, or first name, last name and company. Add up to 10 custom attributes and skip leads you've already contacted.
Every message, streamed to your endpoint
Register an inbox webhook and La Growth Machine posts every LinkedIn and email message, sent or received, to your URL as it happens. Limit it to some campaigns or keep all of them.
Each event carries the message, the conversation, the full lead record and the last 20 messages. Enough to draft a reply with AI, log it in your CRM or alert the right person instantly.
