unsupported_grant_type "grant type not supported"

[Cornelia]

I'm trying to get an authorization token from Salesforce.  Keep getting this response when I test; {"error":"unsupported_grant_type","error_description":"grant type not supported"}

I've changed the grant_type to authorization_code but still get the same error.

Any help is greatly appreciated.

Here is my configuration:

Select the Test link at the bottom of the above page

Hi,

It seems the grant_type you are sending from ServiceNow is not recognized by Salesforce

Did you try generating the token using "Get OAuth Token" link

please check these links; they should help you

Hi Ankur, 

Thank you for responding.

I was able to manually "Get OAuth Token", but am still getting the 'unsupported grant type' response.

I read the 3 links you provided.  Unfortunately, they we not helpful ☹.

I wonder if the issue is in Salesforce?  Any ideas are appreciated.

Best Regards,  Cornelia

Hi,

I could see in the screenshot you are setting grant_type as password
