is this to upload file attachments to a conversations? is there a way to upload file attachments to an opportunity?

Hi @Rob, saw this recently, 'Upload file attachments' under Messages in v2 of API .

Have not played with it, but if you do please do update me/community here and in slack.

Here is the API endpoint, play with it to see if meets what you are trying to do. https://highlevel.stoplight.io/docs/integrations/cd0f7973ec1b6-upload-file-attachments

This would be a great feature to attach files to Customers
