Uploading a PDF into an Application


I am writing a code where Robot logs into Outlook and Save attachments into folder - This is step 1 and am able to do so.

Second step - Read PDF using OCR and store into variables and update metadata into WEb Form. Completed

Third step - POST metadata copy the same pdf and upload into a portal for next steps.

The third step is where am stuck…I am currently stuck at this juncture and not sure how to take this further.
