What does simulating an event from a SIM do?

Simulating an event from a SIM allows you to create test events and send test messages to the API as if they came from your SIM without needing a physical device connection. This is particularly useful for testing and debugging your alerts and webhooks. When you simulate a message:
  • The message will trigger alerts just like a real message from your device.
  • You can specify custom data payload and topics for testing.
  • The message automatically includes the event tags: _REST_API_ (the simluated message event tag) and _DEVICE_<ID>_ (the SIM’s event tag). You cannot simulate system event tags surrounded by underscores.
  • All configured alerts subscribing to _REST_API_ or _DEVICE_<ID>_ will process the simulated event normally.
