our office is using processmaker workflow and I have a task to make automation case, which is triggered by another application. I am doing research that processmaker workflow has that method by creating API and Oauth2 token. So far, I already tested getting access token and then show active users by hitting endpoint API.
Now I must using API for creating new processmaker case, but in start of the case there's attachment field which is mandatory. I am not sure this API could sending binary data or abstract data or whatever it called for attachment.
