Authorize Rentman to access your GHL Contacts API by creating an API key or OAuth credentials, assigning the scope contacts.readonly, and securely storing tokens. Use a server-side proxy to protect secrets and rotate credentials regularly.
Set up the connection from Rentman by registering your app, obtaining client credentials, and configuring the redirect URL. Complete the OAuth2 flow to grant access and refresh tokens for ongoing sync.
Endpoints used in this Rentman + Contacts API integration: – 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 Note: Additional endpoints 18-54 are available in the API docs and can be used as needed.
Trigger: When a new or updated contact is created in GHL
Actions: Create or update the corresponding Rentman contact using POST /contacts/ or PUT /contacts/:contactId; map fields such as first_name, last_name, email, phone, company, and notes.
POST /contacts/ (to create) or PUT /contacts/:contactId (to update) on Rentman
Mapped fields: first_name, last_name, email, phone, company, notes
Trigger: When a Rentman task is created or updated
Actions: Update GHL task via PUT /contacts/:contactId/tasks/:taskId; map fields like title, due_date, status, and notes. Use GET /contacts/:contactId/tasks to fetch existing tasks if needed.
PUT /contacts/:contactId/tasks/:taskId
Task_title, due_date, status, notes
Trigger: When a new note or appointment is added in Rentman
Actions: Create notes and calendar events in GHL for the contact, or update existing ones using the notes and appointments endpoints. Ensure proper field mapping for content and scheduling.
GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments
Notes content, appointment times, and related metadata mapped to GHL notes and calendar fields
No-code automation lets teams connect Rentman and GHL quickly without custom development.
Real-time data sync reduces manual entry, duplicates, and errors across systems.
Centralized data view improves collaboration and speeds up workflows for sales and service teams.
This glossary clarifies API concepts, data mapping, and authentication flows used to connect Rentman with the GHL Contacts API.
Application Programming Interface that allows Rentman and GHL to exchange data programmatically.
Standard authorization framework used to obtain secure access tokens for API calls.
A specific URL in an API that performs a defined action, such as retrieving a contact or updating a task.
The process of aligning data fields between Rentman and the GHL Contacts API so data stays consistent.
When a new GHL contact is created, automatically create or update the corresponding Rentman contact with mapped fields to keep both systems in sync from day one.
Publish task updates from Rentman to GHL so teams on both sides see current work items and due dates without manual exports.
Link notes and calendar events across systems to create a complete, auditable contact history for your team.
Create or gather your GHL API credentials and register your Rentman app. Securely store client_id and client_secret and configure the redirect URL.
Define which events trigger sync (contact created/updated, task changes) and map Rentman fields to GHL fields to ensure data parity.
Test end-to-end flow, verify data accuracy, set up failure alerts, and monitor API quotas to maintain a healthy connection.
Yes. The integration is designed for no-code or low-code setups, allowing non-developers to configure triggers, mappings, and actions. If you have development resources, you can extend functionality with custom endpoints or additional fields. Start with the provided UI to set up basic flows, then broaden coverage as needed. If you run into advanced needs, consider adding a lightweight middleware layer to transform data between Rentman and GHL while keeping core logic in your no-code setup.
You can sync core contact data (name, email, phone, company), tasks, notes, appointments, and tags. Depending on your plan and API access, you can extend to business-level details and additional metadata. Always map fields thoughtfully to avoid data drift and ensure one source of truth for each data type.
Yes. Field mappings are configurable in the integration setup. You can map standard fields (name, email, phone) as well as custom fields if supported by both Rentman and the GHL API. Review a data mapping document and test with sample records to validate accuracy.
Due to high volume, we will be upgrading our server soon!
