Auto-create CRM contacts from incoming SMS conversations to accelerate onboarding
SMS-triggered workflows to engage customers without writing code
Unified data across CRM and messaging for richer insights
Key elements include endpoints, authentication, triggers, actions, and data mapping between GHL’s Contacts API and MessageMedia SMS.
Instant updates occur across systems as data changes.
A callback mechanism that notifies your systems when events happen.
The maximum number of API calls allowed in a time window.
A secure token used to authorize API requests without exposing credentials.
Use SMS to capture leads and automatically create a contact in Contacts API, then trigger follow-up messaging.
Customers text support requests that create or update contacts, notes, and tasks in the CRM.
Send appointment reminders via SMS and update appointment data in Contacts API.
Register credentials with both services and configure secure storage for API keys or tokens.
Align fields like name, phone, email between the two systems.
Create triggers and actions to automate SMS sending from MessageMedia when Contacts API events occur.
The integration exposes a set of endpoints under the Contacts API you can call to manage contacts, notes, tasks, and more. Authentication uses your GHL API credentials with the specified scope; ensure your requests include the proper headers. Start by obtaining an API key with read permissions and test in a sandbox environment.
To authenticate, obtain OAuth tokens or API keys from both services, store them securely, and use them in your requests. Rotate tokens regularly and follow least-privilege access to protect data.
Yes. You can set triggers on Contacts API events (like new contact, update, or phone changes) to kick off SMS actions in MessageMedia. Build robust error handling and retries.
Required fields typically include contactId and phone; name is recommended. Ensure the phone number is in E.164 format for SMS delivery.
API rate limits depend on your plan. Use paginated requests and backoff strategies to stay within limits and avoid throttling.
Map fields between Contacts API and MessageMedia SMS so that name, phone, and notes flow correctly. Use field mappings and transformation rules where needed.
Enable logging and webhook delivery reports to audit sync activity. Use error dashboards to monitor failures and retries.
