Oh, it seems I understood what I was doing wrong. I need to go through the flow as described for “Authorization Code Flow” up to the step with the following response:
{
“access_token”: “[user access token]”,
“scope”:[array of requested scopes]
}
And use this access_token in PUT request scenario for setting channel title. And this is the token which doesn’t expire as 3ventic said. Am I right?
Thank you for detailed explanation.
