Test thoroughly in a sandbox, review logs, and deploy to production.
The Contacts API lets you read and manage contact data from US Global Mail within GHL, empowering you to automate outreach, follow-ups, and segmentation. This integration keeps your CRM and mailing platform in sync without manual data entry. You can pull contact details, related tasks, notes, and appointments on demand. By leveraging the endpoints, you can build robust automations that trigger based on contact changes or task updates.
No-code options exist via connectors and automation platforms that support the GHL Contacts API. For more advanced workflows, you may implement custom mappings or scripts to handle complex field transformations. Even without code, you can configure triggers, actions, and data mappings to automate most common tasks.
Commonly used endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to retrieve tasks, POST /contacts/ to create a contact, and PUT /contacts/:contactId to update records. For task management, POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId are frequently used to create and update tasks tied to a contact.
Authentication typically uses OAuth 2.0 tokens or API keys. You’ll exchange credentials for an access token and include it in request headers. Rotate credentials periodically and follow best practices for secure storage. If your app supports webhooks, ensure they’re authenticated as well.
Yes. PUT and POST endpoints allow updating contact data and task statuses. Automations can be built to push changes back to GHL or US Global Mail, enabling real-time sync across systems and reducing manual data entry.
Supported fields cover core contact data (name, email, phone), business associations, and related tasks/notes. You can extend with custom fields as needed and map them during setup to ensure all essential data passes between GHL and US Global Mail.
Most APIs provide usage metrics and rate limits in the developer console. Monitor your quotas, check error rates, and review logs to optimize calls and avoid hitting limits during peak times.
Due to high volume, we will be upgrading our server soon!
