Refresh oauth 2.0 access token using refresh_token

[niemand23 (N 23)]

Hi guys,

We have an external API for which we are currently authenticating using an access token. This access token has an expiry duration of 1 month so we need to find a way to automatize refreshing the access token using the refresh token provided by our external party.

Using Postman we need to:

1. Send a POST call to the token URL
2. Set authorization type with value OAUTH.20
3. Mark add authorization data to request headers
4. In the body section fill in below fields:
   x-www-form-urlencoded
   client_id
   client_secret
   refresh_token
   refresh_token=refresh_token

And it is working:

But in webMethods using the pub.client.http service I keep getting below response:

{
  "error":"invalid_request",
  "error_description":"Failed to parse request"
}

In the headers document I have Content-Type=x-www-form-urlencoded and I am using below URL:

%tokenURL%?client_id=%clientId%&client_secret=%clientSecret%&refresh_token=%refreshToken%&grant_type=refresh_token

Do you have any idea what is missing here?

Hi

You would have to send the parameters via args for form URL encoded
