I could update my app with example python methods as well

You cannot control the thumbnail of a live stream.

Wheres the body of the response? HTTP Code is half the information.

You leaked your streamkey you should reset it, I edited your post to remove it but the horse has bolted

This is not supported

has no thumbnail field.

So it updated the title/category/tags

Then failed to update the thumbnail as you cannot update the thumbnail.

how do i get body response? you see my full code

i am able to set thumbnails after stream manually from interface but i can’t do that with API?

I want to update description of the stream as well. title tags category works but description and thumbnail fails


Streams have a thumbnail of a recentish screenshot of the stream
Vods can have a uplodated thumbnail but you cannot modify vod’s via the API

Streams don’t have descriptions

I don’t know python well enough to answer that

so after stream ended can I update the video description via API

No, there is no API support to modify VOD’s

ok so my final verification

I can’t set description or thumbnail of streams via API neither before starting stream, neither during stream or after stream ended right?

so these streams after ended they are called as VOD. do you have any plans to let API to modify VOD or I have to use browser interface and do manually?


Streams do not have a settable thumbnail or does a stream have a description.

VOD’s have no API support for modification of the VOD

I cannot speak to what Twitch plans or doesn’t plan to do.

Uservoice is the home for feature requests:

A browser manually has to be used to give a VOD a custom thumbnail and/or description.

Thank you for all answers. 1 final question

during stream I see tags but after stream ended they are empty and can’t be set from browser as well

is this expected?

Tags refer to a stream not to vod content I guess. So they don’t carry over. As to if they should or not I don’t know. that is first party stuff and kinda outside the realm of the forum.
