Show BarCode (QRCode, DataMatrix, etc) from text field in CDM

Hello - I'm attemping to build a type of "contact" appliaction where each contact will have a 9 digit unique code...and when I select a given contact, a new screen will be displayed showing their barcode (generated from the 9 digit code).

 

Any ideas where to start w/ this in PowerApps?

 

I've previously accompished this using a free barcode library using Lightswitch and C#...but not sure the best approach here...

 

Thanks!

Hi @ihayes916,

 

Steps are:

 

1. First of all you need a datasource to store your contacts. (Onedrive Excel Sheet, SharePoint list etc)

2. Next you need a powerApp to connect this datasource and list all the contacts. (PowerApp)

3. Once the contact is selected from PowerApp you need to generate a 9 digit unqiue code. A custom API application could generate a 9 digit unqiue code. (HTTP hosted Custom API)

4. Set up a Microsoft flow to pass a contact (Parameter input) to execute the http custom API. (Microsoft Flow & Custom API)

5. Connect PowerApp to Microsoft flow. (PowerApp & Microsoft Flow)

 

Thanks

Hi @ihayes916,

 

You can directly execute a custom API from Power Apps, so probably you don't need a Microsoft Flow.
