This page describes how you can integrate your ChirpStack instance with Datacake so you can receive data from your devices and send downlinks back to them.

Downlinks are messages Datacake sends back to your devices. They are commonly used for configuration or setting outputs on your devices (where applicable).

In the modal, enter the URL of your ChirpStack instance. Please include the protocol (e.g. https://) and do not add a trailing slash. A valid URL would for example look like this:

Next, in order to add the ChirpStack API key, go back to your ChirpStack server and create a new API key.

You can give it an arbitrary name, for example "datacake". Click "Create API Key" and copy the now shown "Token".

Back on Datacake, paste this token into the "ChirpStack API Key" field and click the "Update" button.

That's it, Datacake is now successfully connected to ChirpStack and you can start receiving data from and sending data to your devices 🎉
