Hello,
As Barry said, this forum is for twitch API support, not general help with other APIs etc.
But since im here, ill answer your question as best as possible:
You need to render the emotes yourself.My API sends the emote tags, which you can then use to replace the emote text with the actual images. Look up the twitch API chat documentation on chat message tags for details.
Good luck!
P.S.: Please make sure to read+abide by both the twitch API ToS and the Logviewer API ToS, which can be found in the lower right corner of the website.
