We've been using the RC api to post conversations to glip. Some of the posts included images. To implement images, we used the "Attachments" feature outlined here:
It worked great and showed the images inline in chat.
However, a few weeks ago (not exactly sure when), all posts that contain attachments quit working.
I finally got around to debugging and can see that it is because RC/Glip is returning a 400 Bad Request error with the message: "Parameter "attachments" is invalid".
I tried getting a post to go through using the api explorer using attachments and I can't get that to work either.
Did something break with attachments? I'm pretty sure the format of our payloads to the api didn't change.
