Access requires a secure API token with the scope contacts.readonly. Use OAuth if available or a personal access token to authenticate requests.
Opinion Stage will use the GHL access token to fetch contact data. Store tokens securely and rotate regularly.
GET /contacts/:contactId – Retrieve a single 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 by business. contacts.write – Token with write access to 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 task as completed. DELETE /contacts/:contactId/tasks/:taskId – Delete a task. POST /contacts/:contactId/tags – Tag a contact.
Trigger: A contact is created or updated in the Contacts API.
Actions: Create or update the corresponding contact in Opinion Stage; update related notes or tasks if needed.
GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger: A task is created or updated for a contact.
Actions: Push task data to Opinion Stage so tasks appear in related records.
PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, status, dueDate, title
Trigger: Notes or metadata are added or updated for a contact.
GET /contacts/:contactId/notes
Key fields: noteId, content, createdAt
Automate data syncing without writing code, reducing manual data entry.
Two‑way data sync ensures all teams see the latest contact information.
Easily scale by adding endpoints as your needs grow, with zero-downtime changes.
Key elements include endpoints, data mapping, triggers, actions, and authentication flows that connect the GHL Contacts API with Opinion Stage.
Application Programming Interface: a set of rules that lets applications talk to each other.
A specific URL in an API that performs a function.
A method for real-time data transfer from one app to another.
The process of granting access to resources after verifying identity.
Whenever a note is added in the Contacts API, push it to Opinion Stage notes for richer context.
Create tasks in the Contacts API from important events in Opinion Stage to trigger follow-ups.
Build a shared dashboard in Opinion Stage showing current contact status and notes.
In GHL, generate an API key with the scope ‘contacts.readonly’ and copy the token.
In Opinion Stage, specify which endpoints to pull and map fields like name, email, and notes.
Run tests, confirm data accuracy, and enable automated data sync.
First, obtain an access token with the scopes you need (e.g., contacts.readonly). Use OAuth if your environment supports it and store tokens securely. The integration will use these credentials to authenticate requests from Opinion Stage to the GHL API. Second, include the token in your API requests and refresh it before it expires to maintain uninterrupted access.
For basic setup, enable endpoints that provide contact data: GET /contacts/:contactId, GET /contacts/:contactId/notes, GET /contacts/:contactId/tasks. Map fields accordingly to ensure name, email, notes, and tasks align between systems. Test in a staging environment, verify data flows to Opinion Stage, and adjust mappings as needed.
Yes, you can push notes and tasks. Use endpoints for notes (GET/POST) and tasks (POST/PUT). Ensure the data format matches and map fields correctly for seamless display in Opinion Stage. Monitor for rate limits and implement proper error handling to recover gracefully from transient failures.
No heavy coding is required if you use no-code automation tools or the built-in connector templates. Some light configuration, field mapping, and endpoint selection are typically enough. If you need custom fields or complex mappings, plan for lightweight scripting or a small middleware layer to transform data.
Test by creating a test contact and performing representative operations (read, update, add notes). Verify data appears correctly in Opinion Stage and that changes propagate as expected. Use a dev or sandbox account if available and review logs for any errors during the test run.
Common troubleshooting includes invalid tokens, insufficient scopes, endpoint misspellings, and data type mismatches. Double-check authentication headers and scope. Refer to the API docs for exact endpoint paths, required parameters, and sample requests to validate your setup.
API documentation is available in the GHL developer portal and the Opinion Stage connector guide. Look for authentication details, endpoint references, and field mappings. Explore sample requests and code snippets to accelerate your integration work.
Due to high volume, we will be upgrading our server soon!
