Postman and Zoom api refresh token

[zoom01 (ZOOMユーザ)]

Description

OAuth 2.0 - Authorization - Documentation

I followed the document above to try refresh token with Postman. The setting is below, and please kindly see the attached.

Method:
POST

Url:
https://zoom.us/oauth/token?grant_type=refresh_token&refresh_token=eyJhb~~~

Header:
“Authorization” : “Basic RjRGN ~~~~ NQ==”

But got following error.

Error
{
“reason”: “Internal Error”,
“error”: “invalid_request”
}

Which App Type (OAuth / Chatbot / JWT / Webhook)?
OAuth

Does anyone have any ideas?

Thanks in advance,
Ying

Hi @zoom01,

Thanks for reaching out about this. A few things to double check:

• Make sure you’re using a valid refresh token (refresh tokens are valid once, and you need to make sure you’re using the latest refresh token that was returned when you originally requested an access_token)
• Ensure that the Client ID:Client Secret are base 64 encoded and match the app you retrieved the access_token for originally
• Try reauthorizing the app and starting with a fresh access_token and refresh_token pair

Let me know if this helps—thanks!
Will

Hi Will,
Thanks a lot. I will try to double check those what you mentioned and see how it goes.

Thanks,
