Wso2 EI 6.1.1 + third party rest api integration - rest

Question

I'm unable to call third party rest api(https://api.github.com/users/hackeryou) in wso2 ei and wso2 esb.
Below is the sample code:
<api xmlns="http://ws.apache.org/ns/synapse" name="VerifyCustID" context="/mambu">
<resource methods="GET" uri-template="/verify">
<inSequence>
<log>
<property name="CustID API" value="*********Inside CustID API********** "/>
</log>
<send>
<endpoint>
<http method="GET" uri-template="https://api.github.com/users/hackeryou"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<send/>
</outSequence>
</resource>
</api>
Below is the error in server log:
ID API = *********Inside CustID API**********

Answer 1

You might have some network connectivity issue to api.github.com:443 (perhaps firewalls etc.)
The API worked fine for me on EI611:
If you are not using the default truststore (client-truststore.jks) that comes with WSO2 or have made changes to it, you might need to import the certificate for api.github.com into the trust store that your WSO2 server is actually using.
Apart from network connectivity and missing certificate in trust store, can't see why your API shouldn't be able to call the remote service
