File upload to Azure blob storage

Azure blob storage provides an extensive Web API support. I suggest to read the documentation, do some R&D and come back with more specific questions.

I quickly checked the Appian App Market and did not find a plugin.

I can able to access azure storage through restapi. From appian i have used integration to access the blob.

In appian interface, i have a file upload component, while uploading files from local folder, the path of the file will be passed as parameter to the integration which will upload the file to azure blob

target is my azure storage . how to invoke integration in file upload.

a!fileUploadField(
              label: "Cover Letter",
              target: rule!AzureBlobCreation(local!filepath&ri!fileName,true,false),
              maxSelections: 1,
              value: ri!fileName,
              saveInto: {ri!fileName,
            })

Not. File upload is always going to a folder in Appian first. You can then move the file to Azure later in the process flow.

I have created folder

Created constant for that

when trying to Upload  from interface, not getting any error but files are not in the created folder

{
  a!localVariables(
   
    a!columnsLayout(
      columns: {
        a!columnLayout(
          contents: {
            
            a!fileUploadField(
              label: "File Upload",
              labelPosition: "ABOVE",
              target: cons!A_AzureFileFolderConstant,
              maxSelections: 10,
              value: ri!fileName,
              saveInto: {ri!fileName   }
            )
          }
        )
      }
    )
  )
}

}

Uploaded files are only accessible AFTER a submit action.
