## Offline QR-Code

Offline? No problem. Generate and let the user download the offline QR code before heading to a location without an internet connection. Learn how to generate this as an alternative to the dynamic QR code through the API.

### STEP 1: Request a Signature Key

We need to send a request to the server, to get a signature key.

For the <mark style="color:blue;">`GET`</mark> request, append this response as query parameters to obtain the offline QR code as a data image in `base64 format`.
