How to Connect Simplicate to Contacts API (GHL)

Simplicate + Contacts API: Powerful no-code automation with GHL and Simplicate

Step-by-step guide to linking the Contacts API with Simplicate

This integration lets you connect GHL’s Contacts API to Simplicate via the Zapier App Connector. Automate the flow of contacts, tasks, notes, and appointments without writing code, so your team stays in sync and productive.

GHL API Authentication (Contacts API)

Authenticate securely using OAuth 2.0 to grant Simplicate access to your GHL Contacts data with granular scope control.

App-Level Authentication for Simplicate

Simplicate uses a standard OAuth 2.0 flow to request access tokens, refresh tokens, and the necessary permissions to manage contacts, tasks, notes, and more.

API Endpoints You'll Use

– 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; – contacts.write; – 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

Top 3 Connections Between Contacts API and Simplicate

1) Create or Update a Contact and Sync Related Tasks/Notes

Trigger: When a contact is created or updated in GHL, fetch the contact details to start a synchronized flow with Simplicate.

Actions: Create or update the corresponding contact in Simplicate; pull and attach related tasks and notes to the contact record.

GET /contacts/:contactId

Actions: Create notes in Simplicate linked to the contact; sync essential metadata like last updated timestamp.

GET /contacts/:contactId/notes

id, contactId, content, createdAt

Benefits of a No-Code Connection Between GHL and Simplicate

No-code setup with a visual builder means fast deployment and easy adjustments without developer time.

Bi-directional data syncing reduces manual data entry and data drift across systems.

Automated workflows trigger in real time, keeping your teams aligned.

Creative Ideas for Integrating Contacts API with Simplicate

1) Lead-to-Contact Automation

Automatically create or update a contact in Simplicate when a new lead enters GHL, with initial task and note templates.

2) Cross-Platform Task Reminders

Sync task creation and due dates so reminders appear in both systems for clear accountability.

3) Contextual Notes & History

Attach notes from GHL to the corresponding Simplicate contact to preserve context and history.

3 Simple Steps to Connect Contacts API with Simplicate

1) Authorize Access

Begin by authorizing the connection in GHL via OAuth 2.0, granting Simplicate the requested scopes.

2) Map Data Fields

Match GHL contact fields to corresponding Simplicate fields (e.g., name, email, phone, task lists, notes).

3) Test & Go Live

Run test synchronizations, verify data accuracy, then enable automatic syncing for ongoing operations.

Frequently Asked Questions

Do I need technical skills to set this up?

Yes. The setup is designed for users without coding experience. The visual builder guides you through authentication, endpoint selection, and field mapping. If you do have coding knowledge, you can customize advanced mappings and workflows. Start with the no-code defaults and expand as your needs grow.

The integration exposes core endpoints for managing contacts, tasks, notes, appointments, and tags. You’ll interact with endpoints like GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/, and more to build comprehensive workflows.

Absolutely. Field mapping is flexible; you can align standard fields (name, email, phone) and custom fields to fit your business data model. This ensures data consistency across GHL and Simplicate.

Authentication uses OAuth 2.0 to grant scoped access tokens. Your tokens are refreshed as needed, and you maintain control over which data is shared. Re-authentication is straightforward if you need to reauthorize the connection.

Security is a priority: data in transit is encrypted, tokens are scoped and time-limited, and you can revoke access at any time. We recommend following GHL and Simplicate security best practices and monitoring logs for unusual activity.

The pattern supports additional GHL endpoints in future updates. You can adapt workflows to incorporate notes, tasks, or tags beyond contacts, depending on API capabilities and your use case.
