Access to the Contacts API requires a secure token with the scope contacts.readonly. Use OAuth 2.0 or a service API key as provided by your GHL developer portal, and ensure the token is included in each request header.
Authorize MarketSharp to access GHL by registering the app, obtaining client credentials, and granting the required scope for reading contacts. Store tokens securely and rotate them 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 for a contact GET /contacts/:contactId/notes – List notes for a contact GET /contacts/:contactId/notes/:id – Retrieve a specific note for a contact GET /contacts/:contactId/appointments – List appointments for a contact GET /contacts/ – List all contacts GET /contacts/business/:businessId – Retrieve contacts for a business contacts.write – Permissions to write 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 new task for a contact PUT /contacts/:contactId/tasks/:taskId – Update a task for a contact PUT /contacts/:contactId/tasks/:taskId/completed – Mark a task as completed DELETE /contacts/:contactId/tasks/:taskId – Delete a task for a contact POST /contacts/:contactId/tags – Tag a contact
Trigger: when a contact is updated in MarketSharp, push the changes to the corresponding GHL contact record.
Actions: upsert the contact in GHL, attach related notes, and optionally create a follow-up task.
GET /contacts/:contactId
key fields: contactId, email, firstName, lastName
Trigger: MarketSharp requests related data (tasks, notes) for a contact
Actions: fetch and merge /contacts/:contactId/tasks and /contacts/:contactId/notes into MarketSharp
Paths: GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes
key fields: contactId, taskId, noteId
Trigger: nightly job to sync all MarketSharp contacts to GHL
Actions: pull /contacts list and upsert in GHL in bulk
Paths: GET /contacts/, POST /contacts/
key fields: contactId, email
Automated data sync removes manual entry and reduces duplication
Bi-directional updates keep both systems current
Faster outreach with accurate contact details and activity history
This glossary explains the core data elements and processes involved in connecting MarketSharp to the GHL Contacts API, including contacts, tasks, notes, and appointments, plus authentication and rate limits.
GHL refers to the platform’s CRM and automation API you’re integrating with. It enables programmatic access to contacts, tasks, notes, and appointments for automation and marketing workflows.
API stands for Application Programming Interface. It defines how MarketSharp apps talk to the GHL Contacts API to read and write data.
OAuth 2.0 is an authorization framework used to obtain access tokens for secure API calls.
Scope defines the permissions granted to the API token, e.g., contacts.readonly, controlling which data can be accessed or modified.
When a new contact is created in MarketSharp, automatically create or update a matching contact in GHL and apply a marketing tag.
Pair MarketSharp tasks with GHL tasks to track follow-ups and deadlines in both systems.
Pull notes from MarketSharp into GHL to keep context for sales reps.
Register MarketSharp as an app in the GHL developer portal and obtain client credentials or an API key with the contacts.readonly scope.
Set up the required endpoints from the list and configure webhooks to receive updates in real time.
Run end-to-end tests, verify data sync across systems, and then enable the integration in production.
In most cases you can start with minimal code by using token-based authentication and a few simple endpoints to read contact data. If you prefer no-code options, consider using a middleware tool to map MarketSharp fields to GHL, while gradually adding business logic as you validate data flows. As you scale, you may add event-driven triggers for real-time syncing.
The primary scope for read-only access is contacts.readonly. This allows reading contact, task, and note data as needed. If you later need to write or update data, you will require additional scopes (e.g., contacts.write) and corresponding permissions from your GHL admin.
Data conflicts can be resolved by implementing upserts with a single source of truth per field (e.g., using contactId as the canonical key). Establish a conflict resolution policy (prefer newer timestamp or higher priority system) and log changes for auditability. Webhooks can help replay and correct records when discrepancies are detected.
You can fetch both: individual contacts by ID and lists of contacts. For initial population, bulk retrieval is common, then you’ll use individual GET calls for synchronization and updates. Debounce requests to respect rate limits.
Sync frequency depends on your plan and rate limits. Real-time or near real-time syncing is possible with webhooks and incremental updates. For large datasets, schedule nightly or hourly batches to balance latency and API usage.
API rate limits apply. Plan for retries and exponential backoff. Use pagination for large result sets and monitor quota dashboards to avoid hitting limits. Caching frequently requested data can reduce call volume.
API endpoint documentation is available in the GHL developer portal. You’ll find endpoint paths, required headers, authentication details, and sample responses. A sandbox environment is recommended for testing before production.
Due to high volume, we will be upgrading our server soon!
