Access the Contacts API using OAuth 2.0 with the scope provided (e.g., readonly access). Store tokens securely and refresh as needed.
Posh uses OAuth 2.0 to authorize access to the GHL Contacts API. Ensure your app is registered, credentials are kept secure, and redirect URIs are configured.
GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags
Trigger: When a new contact is created in Posh, create a corresponding contact in GHL.
Actions: map core fields (name, email, phone), assign initial tags, and create a starter task list.
POST /contacts/
Key fields: email, firstName, lastName, phone
Trigger: A task is marked complete in GHL, update the related contact notes in Posh.
Actions: append completion notes, update task status, and log activity history.
PUT /contacts/:contactId/tasks/:taskId/completed
Key fields: contactId, taskId, completed, notes
Trigger: When contact data changes, apply or update tags in GHL.
Actions: assign tags via POST /contacts/:contactId/tags and update contact segments.
POST /contacts/:contactId/tags
Key fields: contactId, tags
Automate data flow without writing code, using visual Zapier-like workflows between GHL and Posh.
Quickly build multi-step processes that sync contacts, tasks, and notes across apps.
Empower teams with consistent data and faster onboarding without developers.
This glossary defines core concepts and how they relate to integrating the GHL Contacts API with Posh.
The specific URL paths and HTTP methods used to interact with GHL data.
The method by which your app proves identity to the API, commonly OAuth 2.0.
Event-driven callbacks that notify your app of changes in GHL data.
Labels used to segment contacts for campaigns and workflows.
Create a flow that creates or updates a GHL contact when a new contact is added in Posh, then kick off onboarding tasks.
When a contact’s task is due in GHL, notify the Posh team and create a reminder in Posh.
Automatically tag contacts in GHL from Posh events to trigger segmentation and campaigns.
Register the integration, obtain client credentials, and configure redirect URIs.
Run the OAuth flow, grant permissions, and validate access to contacts data.
Create a Zapier-like workflow that reads and updates contacts via the listed endpoints.
The Contacts API lets you read core contact data, tasks, notes, and appointments. Depending on your plan, you may have write access to create or update contacts and related resources. The scope shown (readonly by default) can be expanded to allow writes via POST, PUT, and DELETE endpoints. Always validate permissions before attempted writes.
Authentication uses OAuth 2.0. You’ll obtain an access token after user authorization, and refresh tokens as needed. Store tokens securely and rotate credentials periodically.
Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. Some endpoints may require specific fields; consult the endpoint list for required parameters.
Webhooks are supported to notify your app of changes. Configure your webhook URLs in GHL and handle incoming payloads in Posh or your middleware.
GHL APIs enforce rate limits. Build retry logic with exponential backoff and respect headers indicating remaining quota. Cache responses when possible.
Task-related endpoints include listing tasks, creating tasks, updating task status, and marking completion. See GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, and DELETE /contacts/:contactId/tasks/:taskId.
No heavy coding is required. Use Posh and the GHL integration with no-code tools like Zapier-style workflows to connect endpoints and automate data movement.
Due to high volume, we will be upgrading our server soon!
