Use OAuth 2.0 with the contacts.readonly scope to grant ScoreApp access to contact data. Store tokens securely and refresh them as needed.
To authorize ScoreApp to access GHL, create an OAuth client in GHL and complete the token exchange in ScoreApp to establish a secure session.
Available GHL endpoints for this connection include: GET /contacts/:contactId (retrieve a contact); GET /contacts/:contactId/tasks (fetch a contact’s tasks); GET /contacts/:contactId/tasks/:taskId (get a specific task); GET /contacts/:contactId/notes (list notes); GET /contacts/:contactId/notes/:id (retrieve a note); GET /contacts/:contactId/appointments (list appointments); GET /contacts/ (list contacts); GET /contacts/business/:businessId (list contacts by business). For writing data: API Endpoint9 contacts.write; POST /contacts/ (create); PUT /contacts/:contactId (update); DELETE /contacts/:contactId (delete); POST /contacts/:contactId/tasks (create tasks); PUT /contacts/:contactId/tasks/:taskId (update tasks); PUT /contacts/:contactId/tasks/:taskId/completed (mark completed); DELETE /contacts/:contactId/tasks/:taskId (delete tasks); POST /contacts/:contactId/tags (tag contacts).
Trigger: when a contact is updated in ScoreApp, pull the latest data from GHL and update the contact record.
Actions: create or update contact in GHL, synchronize key fields like email, name, and phone.
GET /contacts/:contactId
Fields: id, email, firstName, lastName, phone, score.
Trigger: when a task is created or completed in ScoreApp, mirror the change in GHL.
Actions: create or update tasks in GHL, sync completion status and due dates.
POST /contacts/:contactId/tasks
Fields: taskId, title, status, dueDate, completed.
Trigger: notes added or updated in either system.
Actions: sync notes between ScoreApp and GHL and attach to the relevant contact.
GET /contacts/:contactId/notes
Fields: id, note, createdAt, updatedAt.
Real-time data synchronization reduces manual entry and errors.
Automated workflows save time with event-driven updates across platforms.
A single source of truth across ScoreApp and GHL helps keep teams aligned.
This section defines API terms and the integration workflow used to connect ScoreApp to the GHL Contacts API, including authentication, endpoints, and data mapping.
API: A set of rules that lets ScoreApp read and update GHL data through the Contacts API with proper authorization.
OAuth 2.0 is the industry standard for granting ScoreApp access to GHL data without sharing passwords.
Webhook: A URL endpoint that GHL can call to push events to ScoreApp in real time.
Endpoint: A specific API path used to perform an action or retrieve data.
Pull contact data via GET /contacts/:contactId and score leads in ScoreApp, then route to sequences in GHL.
Create tasks in GHL when ScoreApp detects engagement milestones.
Sync notes back into ScoreApp to tailor outreach.
Create a GHL developer app, set the redirect URL to ScoreApp, and request the contacts.readonly scope.
Capture client ID and secret in ScoreApp and set up token exchange.
Run a test sync for a sample contact to verify data flow.
The Contacts API requires a trusted OAuth 2.0 flow with the contacts.readonly scope to read contact data. Keep access tokens secure and rotate them periodically. If the token is revoked or expires, use your refresh token to obtain a new access token. Always test permissions in a sandbox before going live. These steps ensure safe, compliant access to contact records from ScoreApp.
Essential endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks for task data, GET /contacts/:contactId/notes for notes, and GET /contacts/ for listing contacts. If you need write capabilities, POST /contacts/ and POST /contacts/:contactId/tasks become available. Use these to map fields and automate workflows between ScoreApp and GHL.
Use OAuth 2.0 with a client ID and secret to authorize ScoreApp against GHL. Exchange authorization codes for access tokens, store them securely, and refresh before expiry. Avoid embedding tokens in client-side code and prefer server-side token handling. Regularly review permissions to ensure they align with your use case.
Yes. If the API scope allows it, you can create and update contacts and tasks from ScoreApp back into GHL using endpoints like POST /contacts/ and PUT /contacts/:contactId. Implement proper conflict resolution to handle changes made in either system.
Endpoint rate limits depend on your GHL plan. Plan for bursts during heavy syncs and implement backoff retry logic. Cache data where appropriate and avoid unnecessary repeated calls to minimize quota usage. Monitor usage in the developer console to stay within limits.
Yes. You can build no-code automations that connect ScoreApp to GHL using webhooks and built-in integration features. For more complex flows, a lightweight server can handle OAuth token management and API calls while keeping your UI simple.
If you encounter authentication failures, check that your redirect URL matches, tokens are valid, and the correct scope is requested. Verify endpoint paths and HTTP methods, and consult the API error messages for guidance. Reach out to support if needed.
Due to high volume, we will be upgrading our server soon!
