Authenticate requests with OAuth 2.0 and securely store access tokens. Your RentCast integration should request a token with the contacts.readonly scope and refresh as needed.
In RentCast, create a dedicated API connection to the GHL Contacts API granting scopes such as contacts.readonly and contacts.write. Use the client credentials to establish a secure connection.
Common endpoints used: 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 GHL, fetch or push related tasks in RentCast.
Actions: Create, update, or mark tasks in RentCast based on GHL changes; pull latest task data into GHL.
GET /contacts/:contactId/tasks
contactId, taskId, taskStatus
Trigger: New or updated notes in GHL trigger updates in RentCast.
Actions: Sync notes, create follow up tasks, attach notes to contacts.
GET /contacts/:contactId/notes
contactId, noteId
Trigger: Appointment events update in either system and sync to the other.
GET /contacts/:contactId/appointments
contactId, appointmentId
Faster onboarding and setup with guided templates and visual builders.
Real time data sync reduces manual data entry and errors.
Scalability across endpoints without custom coding.
Key elements include endpoints triggers actions and data mappings that connect RentCast with the GHL Contacts API.
A specific URL and HTTP method used to access data.
Authorization framework that issues tokens to access resources securely.
A URL that receives real time events from a service.
The data sent or received in an API call.
Automatically tag contacts in RentCast based on GHL activity to improve segmentation and campaigns.
Trigger follow ups in RentCast when a GHL task is completed to keep outreach on track.
Attach notes from GHL to the contact timeline in RentCast for context.
Generate credentials in RentCast and authorize access to GHL.
Map GHL contacts data to RentCast fields and set up triggers.
Run a test sync and enable monitoring dashboards.
You authenticate via OAuth 2.0 in RentCast by selecting the GHL Contacts API connection and following the prompts. Ensure the redirect URI is whitelisted in your GHL app. The second paragraph can mention using service accounts if needed. RentCast also supports API key based connections for service accounts where allowed by your org policy.
Start with pulling basic data using GET /contacts/:contactId and GET /contacts/. This validates read access. Then try to write data with POST /contacts/ and PUT /contacts/:contactId to confirm write permissions and scope configuration.
Yes, webhooks can push updates in real time. Configure event notifications for notes tasks and appointments and handle incoming payloads in RentCast. Real time sync improves responsiveness and reduces manual checks. Ensure proper security and retry logic for missed events.
We use transport layer security TLS and token based authentication. Access tokens are stored securely and rotated regularly. If your org requires it, you can enable additional encryption and audit logging for sensitive data.
No heavy coding is required for typical setups. RentCast provides no code style flows to connect endpoints and map fields. Some advanced mappings may require light configuration but you can complete most tasks with templates.
Test the connection by running a manual sync from RentCast to GHL and vice versa. Check request logs review response codes and verify data appears in both systems. Use a small subset of contacts for testing before full scale.
API documentation for RentCast and the GHL Contacts API is available in the respective developer portals. Look for guides on authentication endpoints data models rate limits and example payloads.
Due to high volume, we will be upgrading our server soon!
