How can I revoke Dropbox business access token?

[harutofujihara]

I want to use "revoke token api" to revoke business account's access token.

I referenced dropbox api document, and tried to use this api.

https/www.dropbox.com/developers/documentation/http/documentation#auth-token-revoke 

But I received 400 error and following message. (I use Laravel and Guzzle for Http client)

I cannot understand the error message  "This API function operates on a single Dropbox account, but the OAuth (truncated...)" .

Could you please explain me what this message mean and how can I solve it?

[2020-11-17 08:38:24] local.ERROR: Client error: `POST https://api.dropboxapi.com/2/auth/token/revoke` resulted in a `400 Bad Request` response:

It looks like your client is truncating the error message. I recommend configuring it to show the whole message, if possible.

For reference though, it would read:

Error in call to API function "auth/token/revoke": This API function operates on a single Dropbox account, but the OAuth 2 access token you provided is for an entire Dropbox Business team. Since your API app key has team member file access permissions, you can operate on a team member's Dropbox by providing the "Dropbox-API-Select-User" HTTP header or "select_user" URL parameter to specify the exact user <https/www.dropbox.com/developers/documentation/http/teams>.

That is, since the /2/auth/token/revoke endpoint happens to be a "user-linked" endpoint, you need to specify a particular user account when calling it, by including a "Dropbox-API-Select-User" header with the member ID of a team member. You can find more information here under "Member file access".

Thank you! I should have configured it to show the whole message.

Maybe I can solve it with you helpful advice.
