Hi,
We have integrated Yammer feed into our client app and we are now trying to display images in there.
As attachment URLs are protected, we are trying to implement a proxy to load files from Yammer and deal with the Yammer authorization token.
The authorization token seems to be properly handled, as we don't face HTTP 401 anymore, however we moved to another issue: the request now returns a HTTP 400 with an error payload:
curl \
--location 'https://www.yammer.com/api/v1/uploaded_files/[REDACTED]/version/[REDACTED]/thumbnail' \
--header 'Authorization: Bearer [YAMMER_TOKEN]' \
{
"reason": "InvalidOrMissingClaims"
}
