Your leads, in any CRM you already run.

LeadSignal captures and qualifies leads from your DMs. The Developer API is how they reach the rest of your stack — GoHighLevel, HubSpot, a spreadsheet, your own software. No waiting on us to build the integration you need.

Pull, or be pushed to — your choice

Pull: one REST endpoint returns your leads, newest first or changed-since — ideal for a scheduled sync. Push: subscribe any https endpoint and LeadSignal sends each event the moment it happens — a new lead, a captured email, a tier change, a booked call. Most teams use both.

1Someone comments your keywordThey become a scored lead in LeadSignal, keyword and source attached.
2LeadSignal fires the webhookA signed POST hits your endpoint within the minute.
3Your CRM fills itselfContact created in your system, attribution intact — nobody typed anything.

Every lead arrives with its story

Not just a name and an email. Each lead carries the keyword that caught them, the source (comment, story reply or DM), the channel, and the tier and score our AI gave the conversation — so your CRM knows a READY lead from a browser before anyone opens it.

{
  "name": "Brandi Underwood",
  "ig_username": "brandi.fit",
  "email": "brandi@example.com",
  "keyword": "CORTISOL",
  "source": "instagram_comment",
  "tier": "HOT",
  "score": 78
}

Built the way you'd want it built

Scoped, revocable tokens

Created in Settings, shown once, hashed at rest. Read access to your leads and nothing else — no master keys.

Signed webhooks

Every delivery signed with your endpoint's secret so you can verify it came from us. Failures retry automatically for hours, with a delivery log you can read in Settings.

Zapier and Make friendly

A catch hook or a scheduled pull is all either platform needs — and from there, hundreds of CRMs and tools with no code at all.

Your data stays yours

The API exposes your leads and their attribution — never your conversations, flows, or AI training. Small surface, on purpose.

Included on Pro and Enterprise plans. An admin creates tokens and webhooks under Settings → Developer API — no sales call, no waiting list.

Wire it up in an afternoon

The docs cover everything: authentication, the lead payload, webhook signature verification and worked examples.
