How to connect LaunchList to the Contacts API (GHL)

A practical, no-code guide to syncing Contacts data between GHL and LaunchList

How to connect Contacts API with LaunchList

This guide walks you through authenticating with GHL, selecting the right endpoints, and building simple automations in LaunchList to keep contacts, tasks, notes, and appointments in sync.

Authenticating with the Contacts API (GHL)

Use the OAuth 2.0 flow or API keys provided for your GHL app to obtain access tokens. Keep tokens secure and refresh them before expiry. Scope for this integration is ‘contacts.readonly’ to start.

LaunchList authentication requirements

LaunchList stores and passes credentials securely to GHL endpoints. Use token rotation and encrypted storage, and ensure your app’s Zapier connection is authorized.

API Endpoints you may 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 LaunchList

1) Create or update LaunchList contacts in GHL

Trigger: When a contact is created or updated in LaunchList.

Actions: Create or update the corresponding contact in GHL via POST /contacts/ or PUT /contacts/:contactId. Map core fields like email, name, and phone.

POST /contacts/ or PUT /contacts/:contactId

email, firstName, lastName, phone, id

2) Sync Notes and Tasks from GHL to LaunchList

Trigger: A new or updated note or task in GHL is detected.

Actions: Create or update corresponding notes and tasks in LaunchList.

POST /contacts/:contactId/notes; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/notes/:id; PUT /contacts/:contactId/tasks/:taskId

contactId, noteId, taskId, content, title

3) Bi-directional contact enrichment

Trigger: Update in either system should reflect in the other.

Actions: Pull latest fields from GHL (GET /contacts/:contactId) and push updates to LaunchList; keep mappings in sync.

GET /contacts/:contactId

contactId, email, name, phone, customFields

No-code benefits of this integration

Automate data sync between LaunchList and the GHL Contacts API without writing code.

Improve data accuracy with real-time updates across apps.

Leverage LaunchList workflows to trigger actions in GHL and keep records consistent.

Creative ideas for integrating GHL Contacts API with LaunchList

Idea 1: Auto-create and update contacts

When a new contact is added in LaunchList, automatically create or update the corresponding contact in GHL via POST /contacts/ or PUT /contacts/:contactId, syncing core fields.

Idea 2: Task and note sync

Automatically mirror tasks and notes between GHL and LaunchList using the relevant endpoints (GET/POST/PUT for notes and tasks).

Idea 3: bi-directional enrichment

Pull latest contact fields from GHL and update LaunchList profiles, ensuring data consistency across platforms.

Three steps to connect Contacts API with LaunchList

Step 1: Authenticate and authorize

Obtain access tokens for GHL and connect LaunchList’s Zapier app; configure scopes (contacts.readonly).

Step 2: Map endpoints and fields

Choose endpoints (e.g., GET /contacts/:contactId, POST /contacts/, etc.) and map fields such as name, email, and phone to LaunchList fields.

Step 3: Build automations

Create Zapier zaps or workflows to perform syncs across Contacts, Tasks, Notes, and Appointments as needed.

Frequently Asked Questions

What is the best way to start a GHL-LaunchList integration?

Begin with the core endpoints to establish a connection and verify data flow. Use GET /contacts/:contactId to pull contact records and POST /contacts/ or PUT /contacts/:contactId to create or update records in GHL, then map key fields like name, email, and phone to LaunchList. Test calls in Zapier or a sandbox environment to confirm data accuracy and field mappings. Next, extend the integration to include tasks, notes, and appointments as needed, handling errors gracefully and setting up retries where appropriate.

For a basic sync, you need core read and write endpoints: GET /contacts/:contactId to read, POST /contacts/ or PUT /contacts/:contactId to create or update. If you need lists, use GET /contacts/ and then loop through results. Ensure field mappings for email, name, and phone are consistent between systems, and monitor responses to handle conflicts or duplicates.

You can often accomplish this with no-code tools like Zapier using prebuilt actions and webhooks. More complex logic can require light scripting or custom mappings, but many common flows (contact sync, note/task propagation) work well with standard Zapier actions.

Authentication typically uses tokens obtained via OAuth 2.0 or API keys. Store tokens securely in your app, rotate them regularly, and implement token refresh. Limit token exposure by using secure connectors and never embedding secrets in client-side code. In Zapier, rely on the built-in authentication options and test the connection thoroughly before enabling writes.

Yes. You can set up bidirectional syncing for notes and tasks by implementing endpoints for both directions (notes/tasks in GHL and in LaunchList). Use consistent field mappings and conflict resolution rules to prevent data overwrites. Regularly audit synced records to maintain data integrity.

If a contact is deleted in one system, you should decide whether to propagate that delete to the other system or to keep a soft-delete flag. Implement a policy to avoid orphaned records, and consider archiving or marking the contact as inactive in the opposite system rather than permanently deleting.

Rate limits vary by API plan. Review GHL’s documentation for quotas and retry guidelines. Build idempotent requests where possible and implement exponential backoff for failed calls to avoid throttling and ensure reliable syncing.
