I’m not sure if there is but it’s just basically joining the string “[https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=](https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=)” with whatever unique value you want. So you can use the join block in the Text drawer to join that string with the green `userId` block explained here: [https://docs.thunkable.com/v/snap-to-place/sign-in-1](https://docs.thunkable.com/v/snap-to-place/sign-in-1).

You’ll need to learn about Web APIs and Thunkable if you’re not familiar. I explain a lot of that – probably much more than you need – here: [API JSON Tutorial (Video)](https://community.thunkable.com/t/api-json-tutorial-video/1140575).
