Everything in this section is about connecting Simbase to something else, rather than working inside the dashboard. Use it when you want events pushed into your own systems, or when you need control that the dashboard's built-in tools don't offer.

The dashboard uses the same name: webhook endpoints are registered under Integrations → Webhooks.

What's in here

• Webhooks, get events pushed to a URL you control the moment they happen: incoming SMS, IMEI changes, SIM state changes and usage limits being reached. Includes the JSON payload for each event type and the retry behaviour

• Usage Guard Toolkit, a build-it-yourself alternative when the native usage limits aren't specific enough. Uses the API and a ready-made automation blueprint rather than a dashboard setting

The Simbase API

The API reference lives outside these docs, at developer.simbase.com. It covers authentication, rate limits, and every endpoint for managing SIMs, usage, SMS and webhooks programmatically.

Use the API when you want to manage a fleet from your own systems rather than the dashboard: enabling and disabling SIMs in bulk, pulling usage into your billing, reacting to a webhook by changing something on the SIM, or building health checks across the fleet.
