Use your integration tool to connect Gmelius to Contacts API using the endpoints listed above.
Define triggers, actions, and data mappings to automate processes.
The GHL Contacts API provides programmatic access to contact data, tasks, notes, and more. It enables automation of common workflows without manual data entry. You can read data to build dashboards, and write data to keep records up to date.
No coding is required if you use a no-code automation tool or built-in connectors. You can configure triggers and actions using templates and drag-and-drop interfaces, while the API handles the underlying calls.
The endpoint list includes endpoints for contacts, tasks, notes, and tags. Use GET for retrieval, POST for creation, PUT for updates, and DELETE for removals. Refer to your API docs for full parameter details.
Authentication is typically done with OAuth 2.0 tokens or API keys. Store tokens securely, rotate credentials regularly, and scope access to only what is needed.
Yes. You can create, update, and delete contact records, their tasks, notes, and tags via the API, subject to permissions and rate limits.
Real-time syncing is possible with webhooks and events. Configure triggers to push updates as soon as data changes.
Consult the API docs for rate limits, authentication requirements, and endpoint parameter details. We’ll provide a quick start guide within this page.
Due to high volume, we will be upgrading our server soon!
