Use OAuth 2.0 or an API token to authorize requests to the Contacts API. Retrieve credentials from your GHL developer dashboard and configure Simpletix to present the token with each call.
In Simpletix, generate a secure API token with the required scopes (read for retrieval, write for updates) and use it to authorize requests to the integration endpoints.
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 Permissions: contacts.write
Trigger: when a contact is created or updated in Simpletix.
Actions: create or update the corresponding contact in GHL; map core fields like name, email, and phone; optionally propagate notes or tasks.
Sync uses POST /contacts/ to create a contact and PUT /contacts/:contactId to update; GET /contacts/:contactId for retrieval.
Key fields: id, email, name, phone
Trigger: a new task or note is created for a contact in Simpletix.
Actions: create a matching task or note in GHL and keep statuses aligned.
Post new tasks with POST /contacts/:contactId/tasks and post notes with POST /contacts/:contactId/notes.
Key fields: taskId, noteId, contactId, title
Trigger: a new appointment or event is created for a contact in Simpletix.
Actions: create appointments in GHL; apply tags to contacts to reflect status or category.
Post appointments with POST /contacts/:contactId/appointments and tag updates with POST /contacts/:contactId/tags.
Key fields: appointmentId, contactId, tagIds
Faster data flow between apps with no-code automation.
Maintains consistent contact records across Simpletix and GHL.
Enables powerful workflows via triggers and actions in Zapier without writing code.
Definitions for API tokens, endpoints, webhooks, and data mapping used throughout this guide.
A secret credential used to authenticate API requests.
An authorization framework that lets apps obtain access without sharing passwords.
A specific URL path for an API function, such as retrieving or updating a contact.
A callback URL that receives event data when something happens in an app.
Consolidate contact data from Simpletix and GHL into a single, easily searchable profile.
Automatically generate follow-up tasks in GHL when events are created in Simpletix.
Build dashboards showing sales, tickets, and contact activity across both apps.
Create API credentials in Simpletix and configure your GHL app to accept the tokens with the proper scopes.
Match core contact fields (name, email, phone) between Simpletix and GHL to ensure clean synchronization.
Run test syncs with sample data to validate end-to-end flow, then enable live operation.
No coding is required for the core setup. The integration is designed to be a no-code bridge between Simpletix and GHL using Zapier or native connectors. You can configure triggers, actions, and mappings through intuitive UI screens. If you need advanced customization, you can add conditional logic using Zapier paths or webhooks without touching code.
The integration exposes a range of endpoints for contacts retrieval, creation, updates, notes, tasks, appointments, and tagging. You can pull a contact with GET /contacts/:contactId, create or modify tasks with POST/PUT endpoints, and attach notes or appointments as part of your workflow.
Authentication uses standard OAuth 2.0 tokens or API keys. Tokens are scoped for the required access and are transmitted securely with each request. If you rotate credentials, update your app settings to maintain seamless access.
Yes. You can write data back to Simpletix via the write-enabled endpoints (POST, PUT, DELETE). Ensure your token has write access and map fields carefully to avoid overwriting important data.
Test the integration in a sandbox or staging environment by creating sample contacts, tasks, notes, and appointments. Verify each endpoint behaves as expected and monitor logs for errors before going live.
If a contact is deleted in either app, the integration can be configured to reflect the change in the other system. Depending on your setup, you may choose to archive, remove, or sync the deletion using webhooks and Zapier workflows.
API documentation is available in the Simpletix and GHL developer portals. Look for sections on Contacts API, endpoints, authentication, and sample payloads. You can also access the integration blueprint and mapping guides there.
Due to high volume, we will be upgrading our server soon!
