I'm migrating from superoffice to hubspot and need to import emails with their attachments.
Do I upload the attachments to the "/filemanager/api/v2/files" -endpoint with the "hidden" -property set to "true". And then take the id from the response and add under attachments when creating email in "Engagement"?
There is something I'm doing wrong when uploading a file. I can't open any file except from pdf's and they seems to be corrupted cause I get error when open them.
When clicking all file types except pdf it looks like this.
