Calling External REST API

I am trying to call a REST API, specifically the login API of Core DDRI(/v1/auth/login) inside process automation, I am following the ProcessModelling for AppWorks Platform 16.7 and I am doing the "Use HTTP connector to connect to an external RESTful webservice. Here is what I did so far.

I created an XML Store Definition Document and an XML config containing this

<configurationsxmlns="http://httpconnector.opentext.com/1.0/configuration">

<url>

URL…

</url>

</connection>

</connections>

</configurations>

Createdan HTTP Connector Application Connector
Createda custom web service with one web service operation with an implementation ofsomething like this

<implementationxmlns="http://httpconnector.opentext.com/1.0/implementation"xmlns:c="http://schemas.cordys.com/cws/1.0"xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/"type="HTTP">

<connection-id>CORE-DDRI</connection-id>

<uri>/v1/auth/login</uri>

<http-method>POST</http-method>

<request-handlerclass="com.opentext.applicationconnector.httpconnector.impl.RestRequestHandler"/>

<req-headers>

<headername="Content-Type">application/json</header>

<headername="Accept">*/*</header>

</req-headers>

<body>

<![CDATA[

{

"tenantId": "tenant",

"user": "user",

"password": "password!"

}

]]>

</body>

</request>

<response-handlerclass="com.opentext.applicationconnector.httpconnector.impl.RestResponseHandler"/>

<valid-response-code>200</valid-response-code>

</implementation>

The problem is when I try to invoke to test the web service operation, I am getting a 415 response which means unsupported media type. I am sure that the login endpoint accepts json since I can call it using postman, but it doesn’t work in process automation. Please help.

@JCTeves You don't need that <request> element with CDATA body. You need to create a new custom service out of your REST endpoint that you can call from your 'Webservice Interface Explorer' artifact. That's where you pass your body (in XML). The RestRequestHandler class will handle the conversion into JSON.

Hi @AppWorks Tips
this is now my implementation and what i did is similar to the one you sent

<implementation xmlns="http://httpconnector.opentext.com/1.0/implementation" xmlns:cws="http://schemas.cordys.com/cws/1.0" xmlns:c="http://schemas.cordys.com/cws/1.0" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" type="HTTP">
<connection-id>TYPICODE</connection-id>
<uri>/posts</uri>
<http-method>POST</http-method>
<request-handler class="com.opentext.applicationconnector.httpconnector.impl.RestRequestHandler">
</request-handler>
<req-headers>
<header name="Content-Type">application/json</header>
</req-headers>
<response-handler class="com.opentext.applicationconnector.httpconnector.impl.RestResponseHandler">
</response-handler>
<valid-response-code>201</valid-response-code>
</implementation>

my soap request in the operation test tool looks like this
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
SOAP:Body
<PostPosts xmlns="posts">
<title>"foo"</title>
<body>"bar"</body>
<userId>1</userId>
</PostPosts>
</SOAP:Body>
</SOAP:Envelope>

but the json body is still not being set

EDIT: soap request

I restarted the service and it works now, my issue is that my request header is not inside the request handler, thank you so much @AppWorks Tips !
