HighLevel: Simple contact creation with a POST operation

HighLevel has an API with lots of features for integration with your applications and processes. But sometimes you just need to add a Contact from an application, like a Web Form.

HighLevel provides a Zapier integration that can fit a lot of needs. If your requirements push you towards a custom integration, thankfully you can use the same endpoint for your needs as well.

Note: this only works with Sub Accounts. Agencies need to use the full API.

Create Key

Your API key can be found and/or regenerated in the Location view at Settings > Business Profile > General Information section. At the bottom there's a section labeled API Key.

Note: Regenerating the API key (clicking the refresh icon) will invalidate any existing integration using the key.

Perform POST request

To create a new contact, perform a POST request to this URL:

https://api.gohighlevel.com/zapier/contact/add_update/

You need headers determining the content type, and the authorization Bearer Token.

This should be the key you generated in the UI, prefixed with Bearer , space included.

Authorization: "Bearer apiKey123"
Content-Type: "application/json"

With a JSON body with these parameters:

{
  "first_name": "Some First Name",
  "last_name": "Some Last Name",
  "email": "name@example.com",
  "phone": "+112355500000",
  "source": "Your App Name",
  "tags": "tag1,tag2,tag3",
  "lead": true
}
