Use your GHL API key to authorize requests to the Contacts API and include it in the Authorization header for each call.
Obtain and securely store your Zengine API credentials so that GHL can perform authenticated calls to Zengine data.
GET /contacts/:contactId — Retrieve a contact GET /contacts/:contactId/tasks — List tasks for a contact GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task GET /contacts/:contactId/notes — List notes for a contact GET /contacts/:contactId/notes/:id — Retrieve a specific note GET /contacts/:contactId/appointments — List appointments for a contact GET /contacts/ — List all contacts GET /contacts/business/:businessId — List contacts for a business contacts.write — Permission to write or modify contacts POST /contacts/ — Create a new 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 complete DELETE /contacts/:contactId/tasks/:taskId — Delete a task POST /contacts/:contactId/tags — Add tags to a contact
Trigger when a new contact is created in GHL via the Contacts API
Action: create a corresponding contact in Zengine and map fields like firstName, lastName, email, and phone
POST /contacts/
firstName, lastName, email, phone
Trigger on update of a GHL contact via PUT /contacts/:contactId
Action: update corresponding Zengine contact fields
PUT /contacts/:contactId
contactId, email, phone, status
Trigger when notes or tasks are created in GHL
Action: create matching notes and tasks in Zengine linked to the contact
POST /contacts/:contactId/notes and POST /contacts/:contactId/tasks
note content, task title, dueDate
Automate data flow without writing a line of code
Speed up deployment with ready to use endpoints and mappings
Achieve real time syncing with webhooks and triggers
Definitions for API, endpoint, authentication, field mapping, and webhooks as they relate to this integration
API stands for Application Programming Interface and allows two apps to talk to each other to exchange data
An endpoint is a specific URL that performs an action on an API
The process of proving identity to access the API, usually via API keys or OAuth
A mechanism for real time notifications from one app to another when events occur
Sync contacts from both systems and merge duplicates using a dedupe rule
Create follow up tasks in Zengine when a GHL contact changes stage
Keep a complete activity history in Zengine by bringing notes from GHL
In GHL, generate a private API key and store it securely
Map fields from GHL to Zengine and select endpoints to use
Run tests, verify data flow, and enable live syncing
You can connect Zengine to the Contacts API without code by using prebuilt endpoints and mappings. Start by authenticating with your GHL API key and then configure field mappings to match Zengine contact records. The result is a seamless, automated data flow between systems.
No heavy coding is required. Use the built in connectors and rules to set up triggers, actions, and mappings. You may need basic familiarity with REST concepts to adjust endpoint paths and field names.
The most commonly used endpoints are creating and updating contacts, listing contacts, and synchronizing notes and tasks. These cover typical CRM to marketing workflows.
The integration uses API keys and standard HTTPS to secure requests. Store keys securely and rotate them regularly. Use scopes to limit access.
Yes, you can sync notes and tasks. Map notes and tasks fields to Zengine activity components and ensure the linkage to the correct contact ID.
Map fields by name or alias. Use the app interface to align GHL contact fields to Zengine fields and validate with sample data.
If there is a conflict, use a dedupe rule or choose the source of truth. You can set priority in mappings and resolve conflicts automatically.
Due to high volume, we will be upgrading our server soon!
