Authenticate to the GHL Contacts API with your API credentials, then connect Stacker to run actions and fetch data securely.
In Stacker, credentials are stored securely and used to call the Contacts API endpoints with proper scopes.

Build automated workflows without writing code; map fields visually and trigger actions on events.
Keep data synchronized between GHL and Stacker with real‑time or batched syncs.
Scale workflows across teams by reusing templates and shared connections.
Understanding terms like API endpoint, authentication, triggers, actions, and data mapping helps you design reliable integrations.
A specific URL path exposed by an API that performs a defined function, such as retrieving a contact.
The process of proving identity to access a resource, typically via API keys or OAuth tokens.
An individual record in GHL that represents a person or organization, used for outreach and CRM.
A to‑do item or reminder associated with a contact within the CRM.
Create a new contact record, automatically pull tasks and notes, and assign initial follow‑ups from Stacker.
Use businessId to group contacts and tailor campaigns via Stacker automation.
Schedule reminders in Stacker when tasks near due dates.
Enter your API key or OAuth credentials and grant permissions to Stacker.
Select the endpoints you need and map fields to Stacker fields.
Run tests, validate data flow, and deploy to production.
The Contacts API lets you programmatically access contact data, tasks, notes, and appointments. It enables your apps to read, create, update, and manage contacts within GHL. Using the Stacker integration, you can automate workflows around these objects without manual data entry. The API endpoints correspond to common CRM actions and can be invoked from Zapier’s App Connector or directly from Stacker’s automation builder.
No code is required to get started with Stacker and the Contacts API. The App Connector provides a visual mapping interface, and typical actions can be configured by selecting endpoints, choosing fields, and setting triggers. Advanced users can still implement custom logic, but straightforward automations are possible without writing code.
Key endpoints include retrieving contacts, listing tasks, and updating task status. You can also fetch notes and appointments to build a complete customer profile in Stacker. The exact endpoints you expose depend on your workflow and the permission scope you choose (for example, contacts.readonly vs contacts.write).
Authentication is typically done with an API key or OAuth token. In the Stacker setup, you’ll securely store credentials and authorize the connection to GHL. Access tokens expire and can be refreshed according to your provider’s policy.
Webhooks can complement the REST endpoints by notifying your app of changes in GHL. If you enable webhooks, you can react in real time to contact updates, task changes, or notes additions, triggering flows in Stacker.
Yes. Rate limits apply to API requests and are documented in the GHL API guide. If you anticipate higher usage, implement batching, caching, and backoff strategies to stay within quotas.
If you run into issues, verify your credentials, check the endpoint paths, ensure the correct scope, and review any error messages or logs from Zapier App Connector and Stacker. Enable test mode, reproduce the issue, and adjust mappings as needed.
Due to high volume, we will be upgrading our server soon!
