Pipeline to remove file attachments

I am not sure if you still need pipeline to delete file from attachments.

You can create a pipeline to delete file from file attachment:

Channel To Use: Fetch JSON
JSON URL: https://api.quickbase.com/v1/files/xxxxxx/[Record ID#]/File attachment FID/0

Outgoing Method type: DELETE
Headers:
QB-Realm-Hostname:domain.quickbase.com
User-Agent:FileService_Integration_V2.1
Authorization:QB-USER-TOKEN yyyyyyyyyyyyyyyyyyyy  

In JSON URL last parameter is "0" so it will delete latest version. If you copy this pipeline step 3 times and if you run these steps back to back it will delete all available 3 versions of file attachments.

You need to make sure that you have correct table Dbid(instead of "xxxxxx" in url), Record ID#, File Attachment field id:
URL would look like this: https://api.quickbase.com/v1/files/xxxxxxx/100/16/0

AND correct user token(instead of "yyyyyyyyyyyyyyyyy" above)

I hope this helps

Thank you
