OnTask web forms can permit a participant in a workflow to upload files that can be used in the workflow and shared with other participants or Zapier Events.
In the detailed view of a web form, the right side panel has an option for Form Fields. Insert a field of the type “File Upload”. Label the field to educate your participants what type of file or attachment you are expecting. If a large amount of information or instructions is needed, consider placing an instruction field prior to the File Upload field to include as much detail as is necessary.
Choose between ‘Single File’ and ‘Multiple Files’ to control whether you are expecting one attachment or more.
For the choice: “Choose the file types to accept” pick ‘Custom list of file types’ and enter the file extensions you will accept (do not include the period).
E.g. docx and clicking the enter key will add this to the list of accepted file extensions.
