To access the GHL Contacts API, you’ll authenticate requests with credentials from your GHL developer dashboard. Use an API key or OAuth flow as provided, and pass credentials securely in request headers.
Grain connects to external services using OAuth 2.0 tokens. When you enable the integration, grant Grain access to your Contacts API account and allow token exchange to establish the connection.
GET /contacts/:contactId — Retrieve a contact by ID GET /contacts/:contactId/tasks — List tasks for a contact GET /contacts/:contactId/tasks/:taskId — Get a specific task GET /contacts/:contactId/notes — List notes for a contact GET /contacts/:contactId/notes/:id — Get a specific note GET /contacts/:contactId/appointments — List appointments for a contact GET /contacts/ — List all contacts GET /contacts/business/:businessId — Get contacts for a business contacts.write — Scope for write access 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: a contact is created or updated in Grain, which then synchronizes to the GHL Contacts record in real time.
Actions: create or update the corresponding GHL contact; update associated notes and tasks.
Method/Path: POST /contacts/ or PUT /contacts/:contactId as needed.
Key fields: email, fullName, firstName, lastName, phone
Trigger: bulk import of contacts from a CSV or form submission.
Actions: create multiple contacts; assign default tags; optionally create initial tasks.
Methods: POST /contacts/ for each record; optionally use batch endpoints if supported.
Key fields: email, name, source
Trigger: changes in GHL reflect back to Grain via webhooks or polling.
Actions: update Grain contact fields; create notes; log task activity.
Methods: PUT /contacts/:contactId; PATCH for partial updates.
Key fields: contactId, lastModified, status
No-code setup via the Zapier App Connector lets you automate data flows without writing code.
Clear data synchronization between Grain and your GHL contacts improves consistency and responsiveness.
Automations for tasks, notes, and reminders save time and reduce manual work.
Understand API basics: endpoints, authentication, triggers, actions, and data mapping used when connecting Grain to the GHL Contacts API.
A defined interface that allows Grain and GHL to exchange data programmatically.
A specific URL path in an API used to perform an action or retrieve data.
An authorization protocol that enables secure token-based access without sharing passwords.
A callback mechanism where the API pushes data to Grain when events occur.
Capture new form submissions in Grain and automatically create corresponding GHL contacts with initial tasks.
When a GHL contact is updated, trigger a task in Grain to follow up with the contact.
Sync notes from GHL into Grain to enrich your activity timeline.
Open Grain, navigate to Integrations, select Contacts API, and grant access to establish the connection.
Map Grain contact fields to GHL contact fields to ensure correct data flow.
Run test syncs, verify data integrity, and enable automation for production use.
The integration lets Grain connect to the GHL Contacts API to read and manage contact data without code. It enables you to fetch, create, and update contacts, tasks, notes, and appointments using standard endpoints. This no-code approach helps you automate everyday workflows.
No coding is required with the Zapier App Connector. You configure triggers and actions in a visual editor, not in code. If you need more customization, you can add filters and simple logic steps within Zapier.
Key endpoints include GET /contacts/:contactId, POST /contacts/, and PUT /contacts/:contactId for common workflows. There are additional endpoints to manage tasks, notes, and tags, giving you a broad set of capabilities for data synchronization.
Authentication uses API keys or OAuth tokens. Keep tokens secret, rotate them regularly, and grant least-privilege access. In Zapier, rely on secure connections and avoid exposing credentials in logs or UI.
Yes, bidirectional sync is possible by configuring two zap templates: one to push updates from Grain to GHL and another to pull updates from GHL back into Grain. Maintain clear field mappings to avoid conflicts.
Test the integration by running sample submissions in Grain and verifying that changes propagate to GHL and vice versa. Check logs, data mappings, and field synchronization during the test phase.
Common errors include invalid endpoint paths, missing required fields, or authentication failures. Verify the correct API credentials, ensure proper field mappings, and review access permissions in both systems.
Due to high volume, we will be upgrading our server soon!
