How to API Leads into HighLevel: A Step-by-Step Guide

API integration is a game-changer for managing leads in Go HighLevel. It allows real-time data transfers, bypassing the need for manual imports via CSV files. Whether you’re receiving leads from a client’s CRM or pushing leads into HighLevel, APIs streamline the process, improve efficiency, and eliminate errors.

In this blog, we’ll dive into how to API leads into HighLevel, explore the tools you’ll need, and walk through a detailed step-by-step tutorial.

Why Use HighLevel API Integration?

API integration provides several advantages:

Real-Time Data Transfer: Leads are sent directly to your CRM as they’re generated, eliminating delays.
Improved Data Security: Avoid sharing sensitive information through CSV files.
Scalability: Manage high lead volumes without manual intervention.

Prerequisites

Before getting started, ensure you have:

HighLevel API Key: Found in the Business Profile section of your HighLevel sub-account.
Postman: A free tool for API testing.
A basic understanding of JSON formatting.

Step-by-Step Guide to API Leads into HighLevel

1. Set Up Your HighLevel API Key

To allow lead integration, generate an API key:

Log in to your HighLevel account.
Navigate to Settings → Business Profile.
Copy the API key from the profile.

Ensure you keep this key secure, as it provides access to your CRM data.

2. Create a Posting Document

The posting document outlines how leads will be mapped from the client’s CRM to HighLevel. Share this document with your client or their tech team.

Key Elements of the Posting Document:

Posting URL: This is the endpoint where data will be sent.
Authorization Header: Add Bearer <Your-API-Key>.
Content-Type Header: Specify application/json.
Body Fields: Include required fields such as firstName, lastName, email, phone, and custom fields.

Here’s an example JSON body for a posting document:

				
					{
  "firstName": "John",
  "lastName": "Doe",
  "email": "john.doe@example.com",
  "phone": "1234567890",
  "tags": ["ClientAPI", "NewLead"],
  "source": "API",
  "customField1": "Value1",
  "customField2": "Value2"
}

3. Test the API Integration with Postman

Postman simplifies API testing. Follow these steps:

Create a New Request:
- Open Postman and create a new request.
- Set the method to POST and paste your Posting URL into the URL field.
Add Headers:
- Under the Headers tab, add:
  - Authorization: Bearer <Your-API-Key>
  - Content-Type: application/json
Set the Body:
- Choose the Raw option and paste your JSON body.
Send the Request:
- Click Send. A successful integration returns a 200 OK status.
Verify the Data:
- Log in to HighLevel and check that the lead data has been received correctly.

4. Refine Field Mapping

HighLevel requires precise field mapping. Common fields include:

Basic Fields: firstName, lastName, email, and phone.
Address Fields: streetAddress, city, state, postalCode, and country.
Custom Fields: Map unique client data such as preferences or referral codes.

Pro Tip: Ensure all required fields are included and formatted correctly (e.g., country should be US for the United States).

5. Implement Custom Tags and Source Tracking

Tags and source tracking help segment and organize leads:

Tags: Add identifiers like Webinar_Attendee or D2C_Lead.
Source: Specify where the lead originated (e.g., Facebook_Ads).

Example JSON with tags and source:

				
					{
  "tags": ["ClientAPI", "D2C_Lead"],
  "source": "Facebook_Ads"
}

6. Collaborate with the Client’s Tech Team

Ensure the client’s tech team maps their CRM fields to your HighLevel fields. Provide clear instructions and test with sample leads to verify accuracy.

Troubleshooting Common Issues

Invalid API Key: Ensure the Bearer prefix is included with the API key.
Field Mapping Errors: Double-check JSON formatting and HighLevel’s field requirements.
Data Not Appearing: Verify that the endpoint URL and headers are correct.

Seamless Workflow: Automate lead transfers for faster follow-ups.
