Authenticate requests to the Contacts API using your API credentials and OAuth token flow to ensure secure access to contact data, tasks, notes, and appointments.
Wave authenticates with GHL using OAuth tokens and API keys exposed through the Zapier App Connector to securely access your data.
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
Trigger: when a contact is created or updated in the Contacts API and synced to Wave.
Actions: create or update a contact in Wave, attach tasks, and attach notes as needed.
Endpoint path example: GET /contacts/:contactId
Key fields: contactId, email, firstName, lastName, phone, company
Trigger: a new or updated note for a contact in the Contacts API
Actions: create or update a corresponding note in Wave for that contact
Endpoint path: GET /contacts/:contactId/notes
Key fields: noteId, contactId, content, createdAt
Trigger: a new or updated task for a contact in the Contacts API
Actions: create or update a task in Wave and mark as completed when needed
Endpoint path: POST /contacts/:contactId/tasks
Key fields: taskId, contactId, title, dueDate, status
Automate data flow between Wave and the Contacts API without writing code or custom integrations.
Centralize workflows across contacts, notes, tasks, and appointments for a single source of truth.
Speed up onboarding and reduce manual data entry with ready-made automations.
A quick glossary of terms used when connecting Wave with the GHL Contacts API, including concepts like endpoints, authentication, webhooks, and data mapping.
Application Programming Interface—rules and protocols that enable one app to communicate with another.
A specific URL and operation in an API that performs a defined action.
Authorization framework that grants limited access without sharing user credentials.
A callback URL that receives real-time data from another service when an event occurs.
Automatically create or update a contact in the Contacts API when a new lead appears in Wave.
Mirror tasks created in the Contacts API to Wave as to-do items.
Whenever a note is added in Contacts, create a corresponding note in Wave under the related contact.
Obtain your GHL API credentials and Wave app credentials to authorize connections.
Set OAuth scopes and secure tokens for both ends.
Map fields between Contacts API and Wave and test your automations.
No extensive coding is required; you can leverage the Zapier App Connector to bridge Wave and the GHL Contacts API. The no-code editor lets you map fields and set up triggers without touching code. The visual builder makes it easy to configure actions and automations in minutes.
The integration supports endpoints that cover retrieving contacts, tasks, notes, appointments, and tags. You can read data with GET endpoints, and create or modify records with POST/PUT/DELETE. You can mix and match endpoints to fit your workflow. For example GET /contacts/:contactId retrieves a contact, while PUT /contacts/:contactId/tasks/:taskId updates a task.
Authentication is handled via OAuth 2.0 and API keys provided through the Zapier connector. Ensure scopes are set to allow reading and writing as needed. Keep credentials secure and rotate keys regularly.
Yes. You can sync notes and tasks automatically by configuring triggers for new or updated items and mapping key fields between GHL and Wave. Real-time or scheduled workflows can keep data aligned across systems.
You can map fields like contactId, name, email, phone, notes, and tasks between systems. Custom fields from GHL can be surfaced in Wave if supported. Always validate data types and formats during mapping.
There are rate limits enforced by both Wave and the GHL API. When building automations, space requests and batch operations to avoid hitting limits. If you approach limits, implement retries with backoff.
API documentation is available in the GHL developer portal and in the Wave App Connector docs within Zapier’s platform. Look for Contacts API endpoints and authentication details. For quick reference, review endpoint references and sample flows.
Due to high volume, we will be upgrading our server soon!
