Let’s say I get into someone’s chat, then click on my name, and I can see my past messages (and I can even scroll up to the top to my first-ever message in their stream).
Is there a way to get my chat history on someone’s stream, using the API? For example, I authenticate with twitch, then I give the username of someone, and then the API gives back the messages I sent on that streamer’s chat.
If something similar is in the docs, I might’ve missed it, but afaik there’s no topics about this particular question.
No, there’s no Chat History endpoint. If you need chat messages then you’d need to capture and save them yourself in real-time.
If you have a use case for needing chat history I’d recommend seeing if a feature request exists on UserVoice, https://twitch.uservoice.com/forums/310213-developers/ to vote for and add your use case, or if not creating one yourself with what your need for it is.
