How to send POST request to Oauth2 token endpoint?

[daniel chicchon]

Currently I'm trying to get an access token utilizing OAuth 2.0 using Postman. I'm following this guide here

Here is my request:

`https://myinstance.service-now.com/oauth_token.do`

My data is set to: form-data-urlencoded

{
grant_type: password,

client_id: id,

client_secret:secret,

username: username,

password:password
}

Except when I run this request, I get a 401 unauthorized response

{

"error_description":"access_denied",

"error":"server_error"

}

Is there somewhere I need to enable access to my token? Or is my request malformed? Any help would be appreciated.

Hi, testing in Postman I don't see an option to add the key:value pairs in the format you have above.

Otherwise using a body that is x-www-form-urlencoded with separate entries for each key:value,
the only possible issue I can see with your data is the existence of white space ' ' prefixing some values and suspect that this could be seen as part of the value string.

Appreciate your help Tony! Turns out it was my own fault and I was using the wrong user credentials and now I am able to access the endpoint.
