To authorize data flow, create API credentials for the Contacts API in GHL and configure OAuth or an API key within Mapulus to enable secure access.
During setup, initiate the OAuth flow from Mapulus, grant permissions for the Contacts API scope (readonly by default), and securely store the access token. Scope: contacts.readonly.
GET /contacts/:contactId — Retrieve a contact’s details; GET /contacts/:contactId/tasks — Retrieve tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task; GET /contacts/:contactId/notes — Retrieve notes for a contact; GET /contacts/:contactId/notes/:id — Retrieve a specific note; GET /contacts/:contactId/appointments — Retrieve appointments for a contact; GET /contacts/ — Retrieve all contacts; GET /contacts/business/:businessId — Retrieve contacts by business; contacts.write — Scope; POST /contacts/ — Create a contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark task complete; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact.
Trigger: a contact is created or updated in GHL
Actions: create or update the corresponding contact in Mapulus; fetch related tasks and notes and reflect changes in Mapulus
GET /contacts/:contactId
contactId, lastModified
Trigger: notes or appointments are added or updated for a contact in GHL
Actions: pull notes (GET /contacts/:contactId/notes) and appointments (GET /contacts/:contactId/appointments) into Mapulus and update records
GET /contacts/:contactId/notes
contactId, noteId, appointmentId
Trigger: a tag is applied to a contact in GHL
Actions: POST /contacts/:contactId/tags to add tags in Mapulus; drive segmentation and workflow rules
POST /contacts/:contactId/tags
contactId, tag
No-code setup lets you connect Contacts API and Mapulus quickly without writing code.
Automated triggers and data flows reduce manual work and keep systems in sync.
No-code tooling like Zapier App Connector makes maintenance easy and accessible to non-developers.
Core concepts you’ll encounter include API calls, authentication, endpoints, data mappings, and the movement of contact data between GHL and Mapulus.
API (Application Programming Interface): a defined set of rules that allows software systems to communicate and exchange data.
A specific URL in an API that triggers an action, such as retrieving a contact or a note.
The process of proving identity and granting access to the API using keys or tokens (OAuth, API keys).
A label attached to a contact to categorize and trigger automated workflows.
Pull external data or activity history into Mapulus during sync to enrich contact records.
Automatically create and assign tasks in Mapulus based on contact changes in GHL.
Track changes across systems and generate cross-platform analytics for better decision making.
Set up credentials in GHL and authorize Mapulus to access the Contacts API.
Map the Contacts API fields to Mapulus data structures and select endpoints to sync.
Run test flows, review logs, and refine mappings for reliability.
No-code setup is supported via Zapier App Connector and the Mapulus integration; most users can configure via the UI. For advanced needs, you can customize mappings and triggers using the endpoints listed.
At a minimum, use GET /contacts/:contactId to pull core data and GET /contacts/:contactId/tasks, /notes, and /appointments to fetch related data. Use POST /contacts/ to create, PUT /contacts/:contactId to update, and POST /contacts/:contactId/tags to apply tags; ensure your mappings reflect the fields you need.
Authentication uses standard OAuth or API keys; tokens are stored securely and scopes are limited (readonly by default). Rotate credentials regularly and monitor access to prevent unauthorized use.
Yes, with proper write permissions you can create and update contacts via POST /contacts/ and PUT /contacts/:contactId. Be mindful of de-duplication and field mappings to avoid duplicates and data loss.
Check the OAuth flow status, verify credentials, and confirm the scope matches your setup. Review API responses and application logs; test endpoints with a tool like Postman to isolate issues.
Yes—Zapier App Connector provides a no-code bridge between GHL and Mapulus for common workflows. Use it to map fields, set triggers, and route data without writing code.
Typical mappings include contactId, name, email, phone, notes, tasks, and tags. You can extend mappings for custom fields by using Mapulus data models and the endpoints listed above.
Due to high volume, we will be upgrading our server soon!
