Was this removed a while back where it showed a snippet of the topic? I believe it was like 120 char max or something like that?
Yeah it's been removed, the teaser object looks like this now:
{
"teaser": {
"pid": "9392",
"username": "julian",
"userslug": "julian",
"picture": "https: //secure.gravatar.com/avatar/e1565907855fffe8433c31671a49f177?size=128&default=identicon&rating=pg",
"timestamp": "2014-04-22T14: 19: 01.715Z"
},
"user": {
"username": "mnv2k2",
"userslug": "mnv2k2",
"picture": "https: //secure.gravatar.com/avatar/2bf741f9373ecafcf96295343a9fbade?size=128&default=identicon&rating=pg"
},
"index": 0
}
I'm assuming it was removed because it slowed down page loading, I think the ideal way is to grab the topic TID and then make a new call to load the teaser (this isn't exposed to the API just yet, check here for progress)
@psychobunny Yeah I did remember this but I forgot when it was removed or whether it was removed completely or not. Any how, thanks for creating an issue for it.
