Solved: Need help with how to define service call out. - Page 2

snowamigos · 03-27-2019 08:11 AM

my flow is I need to call an API to get the token and then call the actual API with that token.

I was able to get the token directly calling the token URL from postman without any issues. (screen grab below)

But when I am calling the same endpoint via apigee, I am getting 401 ( endpoint throwing 500).

I understand that I am doing something wrong in my service callout. (screen grabs below)

Postman call via proxy. (please observe I am sending my request details for the actual endpoint in the body)

Apigee Service call out

Apigee Trace Error:

Please let me know if you need more details?

It looks to me that

in postman you are using a request content-type of x-www-form-urlencoded
while in The ServiceCallout you are using a request content-type of application/json

Have you tried to use x-www-form-urlencoded in the SC?

<ServiceCallout name='SC-1'>
  <Request>
    <Set>
     <Headers>
       <Header name='content-type'>application/x-www-form-urlencoded</Header>
     </Headers>
     <FormParams>
       <FormParam name='username'>godino@google.com</FormParam>
       <FormParam name='password'>ILoveAPIs</FormParam>
       <FormParam name='grant_type'>password</FormParam>
       <FormParam name='client_id'>ABCDEF</FormParam>
       <FormParam name='client_secret'>1234567</FormParam>
     </FormParams>
     <Verb>POST</Verb>
    </Set>
  </Request>
  <Response>SNPOCAuthResponse</Response>
  <HTTPTargetConnection>
    <SSLInfo>
        <Enabled>true</Enabled>
        <IgnoreValidationErrors>true</IgnoreValidationErrors>
    </SSLInfo>
    <Properties>
      <Property name='success.codes'>2xx, 3xx, 4xx, 5xx</Property>
    </Properties>
    <URL>https://myserver.com/oauth_token.do</URL>
  </HTTPTargetConnection>
</ServiceCallout>

Anything inside the FormParam text element is treated as a message template, so you can refer to context variables by wrapping them in curlies like this:

       <FormParam name='username'>{my_username}</FormParam>
