Need help plz to create app

I have created a barcode scanning button. I want that when I press the scan barcode button, it should display all the details of that barcode against its FNSKU result from the Google Sheet, such as Linnworks SKU, Linnworks Title, and COUNTRY.

You already connected Google sheet with your project ? You are able to retrieve data from table ?

After the parameter names, you must put an equal sign (=) to indicate the data that you're submitting.

Do not use:

?IDqwerty

Use:

?ID=qwerty

See the difference?

You can also work free of scripts:
