Is it possible to update an attachment?

Hola Bill, check this thread to see if it helps. I believe that you can modify the image file and write it directly to the directory. As long as you save it with the same name, which is the ID valve of the attachment record.

Hi,

We have an application that's going to digitally sign attachments on EspoCRM (v 5.1.2)

Until now, we have sucessfully downloaded and signed the files, but updating them is not working.

We have tried PUT and PATCH request to /api/v1/Attachment/{id} with the file encoded in JSON like this:

{
"file": "data:application\/pdf;base64,(encodedbytes...)"
}

The request returns 200 OK, but the attachment is not updated

Are we missing something?

It's ok to update the files in /data/upload directly ?

Thanks for your help,
