Hi @d.bazarbayeva

Have you take a look at the built-in keyword here:

Normally, on your page would exist an input element, you just need to capture this object using the Spy Tool and then use the UploadFile keyword to send the file (by passing in the path to the file) to the input. Please try and see if it helps.
