Access is controlled via the GHL authentication flow with the scope: contacts.readonly. Use OAuth 2.0 or API keys as supported, and keep tokens secure.
Housecall Pro must authorize the connection and provide a read-only integration token or OAuth credential for contacts data. Store credentials securely and rotate them as recommended.
– 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: A new or updated contact in Housecall Pro prompts a fetch of the contact details from the GHL Contacts API.
Actions: Pull core contact data (GET /contacts/:contactId) and retrieve related tasks (GET /contacts/:contactId/tasks) and notes (GET /contacts/:contactId/notes).
Method path: GET /contacts/:contactId
Key fields: id, name, email, phone, businessId, contactSource
Trigger: Opening a Housecall Pro contact pulls related tasks and notes from GHL.
Actions: Retrieve tasks (GET /contacts/:contactId/tasks), notes (GET /contacts/:contactId/notes), and optional appointments (GET /contacts/:contactId/appointments).
Method path: GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes
Key fields: taskId, id, subject, dueDate, status; noteId, id, content
Trigger: Changes to a Housecall Pro contact trigger an update to the corresponding GHL contact.
Actions: Update a contact via PUT /contacts/:contactId with fields like name, email, phone; optionally propagate updates to related tasks/notes.
Method path: PUT /contacts/:contactId
Key fields: contactId, name, email, phone, updatedAt
Automate contact syncing between Housecall Pro and the GHL Contacts API to reduce manual data entry.
Provide a centralized view of contacts, tasks, notes, and appointments across both systems.
Faster onboarding and ongoing automation without custom coding.
This section defines core elements and processes used in the integration: API, Endpoints, Authentication, Scope, and data mapping.
Application Programming Interface that enables systems to communicate and exchange data.
A specific route in an API that performs a function, such as /contacts/:contactId.
Authorization framework that grants access without sharing user credentials.
Permissions granted by a token, e.g., readonly vs read/write.
Set up a workflow that creates or updates a GHL contact when a Housecall Pro client is added or changes status.
Link service appointments and notes between systems to get a complete activity history.
Configure conditional alerts to notify teams when a contact status or key field is updated.
Obtain credentials with scope: contacts.readonly and configure your app in the GHL developer portal.
Query GET /contacts and GET /contacts/:contactId to verify data retrieval.
Set up workflows to push data between Housecall Pro and GHL.
With the Contacts API you can read contact data, tasks, notes, and appointments. You can pull related fields like businessId and contactSource. The read-only scope keeps access safe. If you need to modify data, you’ll require additional permissions and a different workflow. In practice, this means you can build dashboards and automations that reflect current data without writing to the source systems by default.
No heavy coding is required if you use a connector or automation tool. Some mapping or small scripting may be needed to align fields between Housecall Pro and GHL, but you can often get started with a no-code workflow.
Supported methods include OAuth 2.0 tokens and API keys. Use OAuth when you want user-based access and refresh tokens; use API keys for server-to-server flows. Never expose tokens publicly.
GET endpoints are read-only and do not modify data. Endpoints that write data (POST, PUT, DELETE) require appropriate scopes and secure handling.
Respect API rate limits by implementing retries with backoff and caching where possible. Design your workflow to stagger requests and gracefully handle errors.
Yes. You can update a Housecall Pro contact via PUT /contacts/:contactId when you have the proper authorization in place. Ensure you map fields accurately to avoid data mismatch.
Refer to the official developer docs and sample payloads within the integration guides. These include example GET and PUT requests, plus field mappings.
Due to high volume, we will be upgrading our server soon!
