Access to the Contacts API is secured with OAuth 2.0 Bearer tokens. Register Sprout Studio as an app in GHL, obtain client credentials, and exchange them for access tokens with the correct scope (contacts.readonly).
Sprout Studio uses OAuth 2.0 flows to authorize calls to the GHL Contacts API. Request the necessary scopes, securely store tokens, and refresh them as needed.
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 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 – Write scope for contacts POST /contacts/ – Create a 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 a tag to a contact
Trigger: A contact is created or updated in GHL, which starts a sync to Sprout Studio.
Actions: Upsert the corresponding contact in Sprout Studio; map name, email, phone, and custom fields; pull related tasks and notes as available.
Method paths: Use GET /contacts/:contactId for retrieval, then POST /contacts/ to create or PUT /contacts/:contactId to update in Sprout Studio.
Key mappings: id -> external_id, firstName -> first_name, lastName -> last_name, email, phone, businessId -> company_id
Trigger: A task or note is created or updated in Sprout Studio.
Actions: Update related tasks and notes in GHL using endpoints like PUT /contacts/:contactId/tasks/:taskId and GET /contacts/:contactId/notes.
Paths: POST /contacts/:contactId/tasks (to create), PUT /contacts/:contactId/tasks/:taskId (to update), and GET /contacts/:contactId/notes (read notes).
Fields: taskId, contactId, title, dueDate, status; noteId, note, date.
Trigger: When notes or appointments are added/updated in Sprout Studio.
Actions: Expose notes and appointments data in GHL; if possible, pull via GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments.
Paths: GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments; no create endpoints in this view.
Fields: note_id, contactId, note, date; appointmentId, date, time, location
Automate data synchronization between GHL and Sprout Studio without writing code.
Improve data accuracy by mapping essential fields and maintaining a single source of truth.
Speed up onboarding and execution of workflows with pre-built connectors and triggers.
This glossary defines core data elements and processes used to connect the GHL Contacts API with Sprout Studio.
Application Programming Interface (API): a set of rules and endpoints that allow Sprout Studio to request and update data in GHL.
OAuth 2.0 is the authorization framework used for secure access to the GHL API from Sprout Studio.
Endpoints are the URLs you call to interact with GHL data, including contacts, tasks, notes, and appointments.
Scopes define the access level granted by the token, for example, contacts.readonly.
Pull contact details from GHL and enrich Sprout Studio profiles with missing fields for a richer CRM experience.
Create Sprout Studio tasks when a GHL task is assigned or updated, keeping teams aligned.
Sync notes between GHL and Sprout Studio to ensure context follows the contact across systems.
Create an app in GHL, obtain client credentials, and authorize Sprout Studio to access the Contacts API.
Define how GHL contact fields map to Sprout Studio fields (name, email, phone, notes).
Run end-to-end tests, verify data integrity, and monitor logs for errors.
Answer 1: The GHL Contacts API lets you read and write contact data, including tasks, notes, and appointments. It enables Sprout Studio to pull contact details and push updates as part of automated workflows. Answer 2: Use OAuth 2.0 to authorize securely and limit scopes to what Sprout Studio needs (e.g., contacts.readonly for read-only scenarios).
Answer 1: You can connect without coding by using Zapier or an App Connector to bridge Sprout Studio and the GHL API. Answer 2: If custom mappings are required, you may implement a lightweight middleware script, but no-code options cover most workflows.
Answer 1: Endpoints available include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, and related task/note endpoints. Answer 2: Writing (POST/PUT/DELETE) capabilities depend on your GHL configuration and token scope.
Answer 1: The connection uses OAuth 2.0 Bearer tokens over HTTPS. Tokens are scoped to your requested permissions, and should be stored securely. Answer 2: Always validate token expiry and implement refresh logic to prevent failed requests.
Answer 1: Data mapping supports core fields like name, email, phone, and custom fields. Answer 2: You can extend mappings to include notes and tasks where the API supports write operations.
Answer 1: Some endpoints only support read operations (notes/appointments in this setup). Answer 2: When write is supported (contacts, tasks), Sprout Studio can push data back to GHL according to the mapped fields.
Answer 1: Logs appear in Sprout Studio and the GHL app integration dashboard. Answer 2: Monitor for errors, review request/response payloads, and set up alerts for failures.
Due to high volume, we will be upgrading our server soon!
