Include a File Upload question in your formless to let respondents attach files to their answers. This option allows respondents to upload a file from their computer or mobile device. You can then download the file via the Conversations panel.
Let’s see together how:
In the Journey section, you'll find a gear icon next to each item. Simply click on it to enter the Settings menu.
Go to question type, and from the drop down menu select “File Upload” option.
The upload option will appear in the conversation as a button, by clicking on it, the respondent will be able to upload different types of files, as jpg, pdf and mp4.
If you’re not making the question “required” there will be the option to skip the file upload.
