Access to the Contacts API requires a secure OAuth 2.0 token or API key with the scopes you need, such as contacts.readonly.
To connect When I Work to the Contacts API, generate and securely store an API key or OAuth token and attach it to your GHL connection in the Zapier app.
Endpoints supported include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/tasks/:taskId, GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id, GET /contacts/:contactId/appointments, GET /contacts/, GET /contacts/business/:businessId, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags

Definitions of common terms used: endpoints, triggers, actions, fields
Application Programming Interface; a set of rules to access data
Specific URL path to access a resource in the API
Open Authorization; a standard for secure delegated access
Callback endpoint that sends data when an event occurs
Automatically assign tags when a new contact is created in When I Work
Update contact tasks in GHL when tasks change in When I Work
Keep notes in sync across systems for a complete history
Obtain OAuth tokens or API keys for secure access
Enable required endpoints and scopes for data you need
Create triggers and actions in the visual editor to automate workflows
No coding is required. Use a no-code automation builder to connect When I Work with the GHL Contacts API. You can set up triggers, actions, and data mappings visually. If you need more control, you can also use direct API calls.
You can access contact details, tasks, notes, and appointments. Read permissions are available via the scopes, and you can write data if your token includes the required permissions.
The integration uses secure authentication (OAuth2 or API keys) and encrypted transmission. Access is scoped to your needs and follows best practices to minimize exposure.
Yes. Set up event-based triggers in When I Work to push updates to GHL, or pull updates from GHL to When I Work using scheduled syncs.
Common endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId.
Use a test or sandbox environment, create sample records, and verify data flow between systems. Most platforms provide a test mode.
API docs, endpoint references, and example workflows are available in the GHL developer portal and Zapier app connector docs.
Due to high volume, we will be upgrading our server soon!
