GMS API Compatibility

SMSBAT supports a compatibility layer with the GMS API. This allows you to migrate your existing integrations designed for GMS directly to SMSBAT without having to modify your message routing schemas, payload structures, or callback listeners.

Connection Settings

To route requests through SMSBAT, update the base URL and authentication credentials in your integration:

Base URL: https://restapi.smsbat.com
Endpoint: POST /api/GMSMessage/send_message
Request Format: application/json
Authentication: HTTP Basic Authentication (uses your SMSBAT API credentials)

The GMS compatibility API accepts a JSON object with the following top-level parameters:
