How to connect Contacts API and SlickText

This guide explains how to securely connect SlickText with the GHL Contacts API, enabling real-time contact syncing, message automation, and enriched contact records. You’ll learn authentication basics, key endpoints, and practical use cases to get up and running quickly.

Authentication with the Contacts API

Authenticate requests to the GHL Contacts API using your API credentials. Use your API key and follow the recommended authentication flow to securely access endpoints such as GET /contacts/:contactId and POST /contacts/.

Authentication with SlickText

Connect SlickText to GHL by storing and rotating API keys securely in your integration. Use standard Authorization headers and token-based access to protect calls between SlickText and the GHL Contacts API.

Core Endpoints You'll Use

Endpoint examples include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, POST /contacts/:contactId/tags, GET /contacts/, GET /contacts/business/:businessId. Use these to build flows that keep contacts, tasks, notes, and tags in sync between SlickText and the GHL system.

Frequently Asked Questions

Is this integration secure and compliant?

Yes. The integration uses industry-standard security practices, including API keys, token-based auth, and encrypted data in transit. Always follow your organization’s security policies when storing credentials. Regular audits and least-privilege access help keep your data safe. Additionally, you can test in a sandbox environment or with test data to ensure compliance before going live.

You can automate contact creation and updates, task creation and completion, and notes synchronization. This enables real-time messaging campaigns, proactive follow-ups, and consistent contact records across SlickText and the GHL Contacts API. Use cases include welcome SMS, post-call follow-ups, and ongoing engagement workflows.

No advanced coding is required. The integration is designed for no-code or low-code setups using API keys and visual workflows. For complex scenarios, you can add custom scripts or use webhooks to tailor behavior, but basic syncing and automation can be achieved without writing code.

Essential endpoints include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes, and POST /contacts/:contactId/tags. These provide core create/read/update/delete capabilities and the ability to drive tasks and notes from SlickText.

Use a secure flow to exchange tokens or API keys. Store credentials in a secure vault, rotate them regularly, and scope permissions to the minimum required. When making requests, include proper Authorization headers and verify responses. Consider using OAuth where supported for an added security layer.

Yes. You can run tests in a staging environment or with sample data. Verify that data maps correctly between systems, and monitor for any discrepancies. After successful validation, deploy to production with monitoring and alerting in place.

Resources include the official API docs, community tutorials, and support channels. You can also consult the integration’s best-practice guides and example flows to jump-start your setup. If you run into issues, reach out to support for assistance.
