Access to the Contacts API requires an API key or OAuth token with scoped permissions (for this page, typically contacts.readonly). Include the token in the Authorization header for every request.
Real Estate Webmasters uses the same secured credentials to access the GHL Contacts API. Ensure your app is whitelisted, redirect URIs are configured, and scopes match your data needs.
GET /contacts/:contactId — Retrieve a specific contact; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Get a specific task; GET /contacts/:contactId/notes — List notes; GET /contacts/:contactId/notes/:id — Get a note; GET /contacts/:contactId/appointments — List appointments; GET /contacts/ — List contacts; GET /contacts/business/:businessId — List contacts by business; contacts.write — Permission to write; POST /contacts/ — Create a contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact
When you need to fetch a contact’s profile, tasks, notes, or appointments for review or display in Real Estate Webmasters.
Use GET endpoints to pull data for a contact, then surface it in dashboards or client records.
GET /contacts/:contactId
contactId, fields to include, related resources
When following up on a lead or birthday/date-specific tasks need to be tracked.
Create, update, or complete tasks using POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, and PUT /contacts/:contactId/tasks/:taskId/completed.
POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
contactId, task details, due date, status
When syncing large contact lists or performing batch updates across records.
Use GET /contacts/ for lists, POST /contacts/ to create, PUT /contacts/:contactId to update, and DELETE /contacts/:contactId for removal.
GET /contacts/; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId
contactId (for updates/deletes), businessId, tags, and field mappings
Faster onboarding flows: automatically create or update contacts from leads and assign initial tasks without writing code.
Seamless task management and notes synchronization across systems for real-time collaboration.
Data integrity and consistency with endpoint-level permissions and clear field mappings.
Core concepts you’ll encounter: API, endpoints, authentication, requests, responses, data mapping, and webhooks. Understanding these elements helps you design robust automations between GHL and Real Estate Webmasters.
A set of endpoints that lets GHL and Real Estate Webmasters exchange data programmatically.
A specific URL path that exposes a function of the API.
Authorization framework used to securely access the GHL Contacts API.
A callback mechanism that notifies Real Estate Webmasters of events in GHL data.
Automatically create GHL contacts from Real Estate Webmasters leads and assign an introductory task to begin the client journey.
Trigger follow-up sequences using tasks and notes when a lead expresses interest in a property.
Consolidate contacts, tasks, notes, and appointments into dashboards accessible to agents and managers.
Request API access, generate an API key or set up OAuth, and ensure the scope is set to contacts.readonly (or higher as needed).
Map Real Estate Webmasters fields to GHL contact fields so data flows correctly between systems.
Run test requests, verify responses, monitor logs, and then deploy to production with ongoing monitoring.
The GHL Contacts API exposes resources for contacts, tasks, notes, and appointments that you can read and manage from Real Estate Webmasters. It supports retrieving, listing, and filtering data to fit your workflows. The API helps you automate client onboarding, follow-ups, and activity logging while keeping data synchronized across systems.
You can implement many common flows with no code using Zapier App Connector or built-in automations. For more complex logic, lightweight scripting or low-code tools can help connect apps and transform data. The API uses standard authentication methods and supports webhooks to notify you of changes in real time.
Supported endpoints include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and related endpoints for appointments and tags. This enables full lifecycle management of contacts and their related activities.
Authentication is performed with an API key or OAuth token included in the Authorization header. Use the appropriate scope (for example, contacts.readonly) to access the resources you need. Rotate credentials regularly and follow best practices for secret management.
Yes. You can create tasks with POST /contacts/:contactId/tasks, update tasks with PUT /contacts/:contactId/tasks/:taskId, and mark tasks complete with PUT /contacts/:contactId/tasks/:taskId/completed. This supports automated follow-ups and workflow tracking.
Rate limits depend on your plan and usage. Expect higher quotas for active real estate workflows. If you anticipate heavy use, plan for batching requests and implementing exponential backoff on errors.
For documentation, examples, and developer support, refer to the integration docs and your support plan. If you need hands-on help, contact our support team via the internal portal or support email to troubleshoot API connections and field mappings.
Due to high volume, we will be upgrading our server soon!
