I creating a bot using REST API. I create an admin user in Mattermost with a personal token and allow overriding pictures and names in integrations.
I need to override the username and icon_url in api/v4/posts when post message using REST API.
But seems that in this case, it didn’t work.
I was spent quite a lot of time figuring out in the internet and doing requests by myself - but no luck.
I am wonder - do we have option to override username and icon_url in api/v4/posts?
