Our API requests have started failing with the error "Request header field yammer-capabilities is not allowed by Access-Control-Allow-Headers".
Before the weekend, everything was working correctly. Anyone else seeing this?
Same problem here, but it is not the first time, and I think we shouldn't change anything: Yammer's API is slowly beginning to be migrated to Office365's API, maybe this is why there is so much errors in this API... (hope so!)
If you want to see what they're working on : https://about.yammer.com/success/engage/grow-your-network/release-schedule
Btw, did you try to post this issue on yammer Developer Network ? This can really help, they are using there own social network to communicate ;)
