Authenticate requests with your GHL API credentials. Include an API key in the Authorization header and apply the scope contacts.readonly for read access. Use secure storage and rotate credentials regularly.
In AlterEstate, configure a secure connection using OAuth 2.0 or an API-key style flow to access GHL endpoints. Store tokens securely and follow best practices for credential management.

A concise glossary of the elements and processes used to connect GHL Contacts API with AlterEstate, including endpoints, authentication, and data objects.
Application Programming Interface: a set of rules that enables software components to communicate.
The process of verifying identity and granting access to protected resources.
A specific URL path that performs an action on a server.
An authorization framework that enables secure access to APIs.
Automatically enrich contact data from external sources when a contact is updated in AlterEstate, reducing manual data entry.
Create tasks in GHL based on new leads captured by AlterEstate to streamline follow-up and ownership.
Post updates to Slack or email when contact changes occur to keep teams aligned.
Obtain your API key from GHL and set the scope for contacts.readonly to enable read-only access by default.
Ping endpoints like GET /contacts to verify connectivity and correct data retrieval.
Move to production, monitor API usage, and implement retries for rate limits.
The GHL Contacts API connection lets AlterEstate securely access and manage contact data, tasks, notes, and related objects via defined endpoints. It enables automation and data synchronization across systems, powered by RESTful calls. This connection is designed to be hands-off after setup, letting your team focus on engagement rather than integration mechanics.
Authentication is about proving identity and granting access. Use your GHL API key or OAuth 2.0 flow as configured in AlterEstate, ensure the Authorization header is present, and scope is restricted to the needed permissions (e.g., contacts.readonly). Regularly rotate credentials and store them securely in your vault or secret manager.
Start with read operations to fetch a contact and its associated data (GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes). Once stable, gradually add write capabilities (POST and PUT) to update contacts and create tasks. Always test in a sandbox or staging environment before production.
Yes. The API supports creating, updating, and organizing contacts, tasks, notes, and tags. Use POST for creates, PUT for updates, and DELETE when removing items. Build your workflows to reflect real-world processes like onboarding, task assignment, and note logging.
Rate limits apply to all API calls. Monitor headers returned by GHL responses, implement exponential backoff, and space out requests during high-traffic events. If you anticipate spikes, consider queueing requests from AlterEstate to avoid throttling.
No heavy coding is required. Leverage AlterEstate’s built-in connectors and prebuilt actions/triggers to map endpoints, enabling workflow automation with minimal scripting. For advanced use cases, light scripting or mapping rules can be added as needed.
Due to high volume, we will be upgrading our server soon!
