Connect your GHL developer credentials using OAuth 2.0 to authorize API requests to the Contacts API. Store tokens securely and refresh them as needed.
Authorize the AddEvent connector with your GHL account using OAuth 2.0, then securely manage access tokens within the connector.

Trigger: Task completed via /contacts/:contactId/tasks/:taskId/completed
Action: POST /contacts/:contactId/tags to apply a Completed tag
POST /contacts/:contactId/tags
contactId, taskId, tag
Trigger: Related task status changes in AddEvent
Action: PUT /contacts/:contactId to update contact fields based on task outcome
PUT /contacts/:contactId
contactId, field updates
Create powerful automations without writing code by linking contact data to AddEvent workflows
Speed up deployments with ready-made endpoints and field mappings
Maintain secure, scalable integrations with OAuth 2.0 and token management
Key elements include endpoints, authentication, triggers, actions, and data mapping used to connect the GHL Contacts API with the AddEvent app.
A specific URL path that performs a defined operation in the GHL Contacts API.
The process of verifying identity and ensuring secure access to API resources, typically via OAuth 2.0 tokens.
The URL pattern used to interact with the API and perform actions or retrieve data.
A label assigned to a contact to categorize, segment, or trigger automation.
When a new contact is created, automatically generate a starter task in AddEvent and tag the contact for follow-up.
Pull contact notes from GHL into AddEvent activities to keep context.
Update contact fields in GHL when a related task is completed in AddEvent.
Obtain OAuth credentials and authorize the connection for both the GHL API and AddEvent app.
Select relevant endpoints (for example, GET /contacts/:contactId and POST /contacts/:contactId/tasks) and map fields to AddEvent.
Run tests, verify data flows, and enable automation in production.
The Contacts API provides programmatic access to contact data including retrieving, creating, updating, and deleting contacts, tasks, notes, and more. It lets you automate common workflows across apps without manual data entry. In this guide you will learn how to connect the Contacts API with the AddEvent app using the GHL App Connector, including endpoint selection and data mapping.
No extensive coding is required. The GHL App Connector provides a no-code workflow builder where you can select endpoints, configure triggers, and map fields to actions in AddEvent. For more complex logic, small code steps can be added, but most use cases are achievable with point-and-click configuration.
The connection can leverage a broad set of endpoints listed in the guide, including retrieving contact data, managing tasks, notes, appointments, and tagging. You can start with core endpoints such as GET /contacts/:contactId to fetch data and POST /contacts/:contactId/tasks to create tasks, then expand as needed.
Authentication is handled via OAuth 2.0. You will authorize the GHL Contact API and the AddEvent connector, exchange access tokens, and store them securely within the app connector. Regular token refresh ensures ongoing access.
Yes. You can trigger AddEvent actions based on changes in contact data, such as a task completion or a new note, by configuring triggers in the App Connector and mapping those events to AddEvent workflows.
There is no hard-coded limit in the guide, but API rate limits and plan restrictions may apply. Plan accordingly and implement batching or exponential backoff where needed.
API keys and OAuth tokens are managed within the GHL developer console and the AddEvent connector. You will obtain client IDs, secrets, and token endpoints during setup, then store tokens securely in the connector.
Due to high volume, we will be upgrading our server soon!
