Hello David,
Thank you for your quick response. I feel ashamed on such trivial error ;(
I tried to rewrite request and send it to API. Yes, the response is changed. But still, there is problem. This time, I get following error in the response.
'{"errorCode":403,"errorId":"ap3int-sv2.2020060811.2916844","errorMessage":"bad refresh_token (check URL encoding)"}'
So, I try to confirm that my refresh token is correct. Here is the response when I send a request with grant_type=authorization_code
{"plan":"proStandard","provider":"Google","id":"[ID]","scope":"https://cloud.feedly.com/subscriptions","token_type":"bearer","access_token":"[ACCESS TOKEN]","expires_in":604800,"refresh_token":"[REFRESH_TOKEN]"}
I surely checked that the refresh token is correct. And it's clear that my plan is proStandard. In this situation, what would be a reason for this error?
