I have been working in a service chaining that answers me with a Bearer Token using in WSO2 EMM. I made a proxy in ESB and then I passed to a new sequence that makes the nex
I had the same error. This is my solution, similar to previous but in Json:
<property name="scope" scope="default" type="STRING" value="myScope"/>
<payloadFactory media-type="json">
<format>{"grant_type":"password","username":"admin","password":"admin","scope":"$1"}</format>
<args>
<arg evaluator="xml" expression="get-property('scope')"/>
</args>
</payloadFactory>
<!-- authorization header with consumer-key:consumer-secret in Base64 -->
<header name="Authorization" scope="transport" value="Basic RUVyY0VRejFfU..."/>
<header name="Content-Type" scope="transport" value="application/x-www-form-urlencoded"/>
<property name="messageType" scope="axis2" type="STRING" value="application/x-www-form-urlencoded"/>
<call blocking="true">
<endpoint key="GetToken"/>
</call>
I got it this is the answer
