How to Connect InvestorBase to the Contacts API (GHL)

A practical guide to wiring InvestorBase with the Contacts API

Connecting InvestorBase to the GHL Contacts API in minutes

This integration lets InvestorBase access and update contact data via the GHL Contacts API. Authenticate securely, then use the listed endpoints to read contacts, create tasks, add notes, and manage appointments.

Authenticate with the Contacts API

Use your GHL credentials to authorize requests. Include your access token in the Authorization header (Bearer token) and follow the documented scopes.

InvestorBase Authentication

InvestorBase uses OAuth 2.0 to securely connect to GHL. Store tokens securely, rotate credentials regularly, and limit scopes to what is required for syncing.

Frequently asked questions about the InvestorBase to GHL Contacts integration

What data can I access with the Contacts API?

You can read and pull essential contact data through the GET endpoints and use filters to scope results. Write access is controlled by your API credentials and the app’s granted scopes. If your role includes read-only access, updates must be performed via approved write endpoints after proper authentication. Always align field mappings to ensure name, email, and tags transfer accurately between InvestorBase and the GHL Contacts API.

Authenticate requests with an OAuth 2.0 flow or an access token provided by GHL. Include the token in the Authorization header for each call. Rotate tokens regularly and restrict token scope to the minimum necessary (e.g., read-only for data retrieval). If a token expires, refresh it using your standard OAuth workflow.

Yes, depending on your credentials. Use POST /contacts/ to create new contacts and PUT /contacts/:contactId to update existing ones. Ensure field mappings (name, email, phone, tags) are consistent and validated to prevent data loss. Proper error handling will help you gracefully manage conflicts or validation errors.

For task synchronization, use POST /contacts/:contactId/tasks to create tasks, PUT /contacts/:contactId/tasks/:taskId to update, and PUT /contacts/:contactId/tasks/:taskId/completed to mark completion. This aligns with typical task lifecycle needs and keeps task data in sync across systems.

Yes. No-code options exist via Zapier or built-in webhooks that trigger actions between InvestorBase and the GHL Contacts API. These tools allow you to set up common sync patterns without writing code, though some advanced scenarios may still require custom scripting.

Start by checking response codes and error messages from API calls. Verify authentication tokens, endpoint permissions, and the exact field mappings. Review quotas and rate limits, and use retries with backoff. When in doubt, run a minimal test (read a single contact) to isolate issues before scaling up.

Map core fields like name, email, phone, and tags consistently between systems. Use a stable identifier (contactId) to avoid duplicates. For complex fields (tags, business info), align your schema to use the same tag conventions and business identifiers across both platforms.
