Hi all,

i m facing following test connection error message after appropriately setting all the configurations for the application:

“Exception occurred while getting response for url: /GetUser and the exception is : Unable to generate access token. Response returned: {“error”:“invalid_request”,“error_description”:“MSIS9631: Received invalid OAuth request. Multiple client authentication methods were attempted.”}”

Anyone who have had this issue while setting up web service connector in IIQ?

Hi @rabshrestha,

its possibile the configuration that you have selected in SP is not correct for the webservice.

The OAuth2 method is correct, but is possible that the token call want credential or something else.

Do you try in postman/insomnia?

Hi Emanuele,
upon trying from Postman, i see a status code as 403 Forbidden.

May we assume this error is because of permission?

[enistri_devo (Emanuele Nistri)]

User permission or the authentication method is not correct. Talk with webservice developer/admin about this, maybe you have wrong info about the authentication

403 Forbidden.

Hi @rabshrestha ,

A 403 Forbidden error is an HTTP status code that indicates a client doesn’t have permission to access a web page or serve. So, check with the webservice team that whatever the credentials you are using have the right permission or not and correct or not. And also, you confirmed that it is also not working. So, you have to check with them and get the correct credentials.
