Comarketing API

List Preferred Partners, send a lead, read the leads you sent, and register a webhook.

The API base URL is https://www.comarketing.com. Create a cm_ key in Integrations, then call the routes in the API reference.

Sending a lead writes a row in Leads Sent. POST /api/external/leads is a different route and stays unchanged.
