The GHL Contacts API uses OAuth 2.0 authentication with the defined scope contacts.readonly. For write operations you will request additional scopes and secure your credentials in OfficeRnD
Configure the connected app in OfficeRnD to request the GHL scopes, set the correct redirect URL, and securely store refresh tokens for ongoing access
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 contacts.write 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 GHL
Create or update the corresponding contact in OfficeRnD and attach related tasks or notes as needed
Use GET endpoints to pull contact data and related tasks and notes; use PUT to update when necessary
Key fields to map: id, email, phone, name, tags, businessId
Trigger when an OfficeRnD contact is updated or a task is completed
Push changes to GHL via endpoints such as PUT /contacts/:contactId and POST /contacts/:contactId/tasks
Paths: PUT /contacts/:contactId, POST /contacts/:contactId/tasks
Map fields: id, officeRnD_id, updatedAt, status, tags
Trigger when notes or tasks are created in either system
Paths: GET /contacts/:contactId/notes, POST /contacts/:contactId/notes; GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks
Key fields: id, contactId, noteId, taskId
Rapid setup with no code to configure real time sync between systems
Centralized contact data across OfficeRnD and the GHL Contacts API for a single source of truth
Automated workflows reduce manual data entry and errors
This glossary explains terms used in this guide such as API endpoint, authentication, webhook, mapping, and scope
A specific URL in the GHL API used to access a resource or perform an action
A mechanism for receiving real time notifications from the GHL API when events occur
The standard authorization framework used to grant limited access to GHL resources
The URL in your app where GHL redirects after user authentication
Automatically create a contact in GHL when a new contact is added in OfficeRnD and assign onboarding tasks
Sync activity notes and tasks between systems to maintain a complete timeline
Tag contacts in GHL from OfficeRnD based on business rules to trigger automations
Obtain your API key, register your OfficeRnD app in GHL, and configure required scopes
Set up the OAuth 2.0 flow, exchange tokens, and store securely in OfficeRnD
Run test requests against the endpoints, verify data mapping, and deploy to production with monitoring
No code is not required to connect using no code tools or pre built connectors. You can also use simple automation platforms to map fields between OfficeRnD and GHL without writing code. For custom needs, light scripting can be used to handle complex mappings.
GHL uses OAuth 2.0 for authorization. You will obtain an access token with scopes such as contacts.readonly for read operations and additional scopes for write actions. Manage tokens securely and rotate them as recommended by the provider.
Start with basic read endpoints like GET /contacts/:contactId to validate data flow. Then extend to notes and tasks endpoints to build a richer sync. Always test with a small subset of contacts before full rollout.
Write operations can be performed with endpoints such as PUT /contacts/:contactId and POST /contacts/:contactId/tasks. Implement data integrity checks and conflict resolution to avoid overwriting valid data in either system.
Respect API rate limits by implementing exponential backoff and retries. Use idempotent requests where possible and monitor the logs to adjust concurrency and batch sizes.
Yes. No code solutions exist via connectors and automation platforms. For bespoke needs, you can extend with minimal scripting to handle special mappings or event triggers.
Map core fields consistently (id, email, name, phone) and align IDs across systems. Decide which system is the source of truth for each field and implement fallback logic for missing data.
Due to high volume, we will be upgrading our server soon!
