WebService Task in Camunda

Question

In Camunda BPM designer, I couldn't find activity and for invoking a REST or SOAP based webservices. Is it only possible to invoke through wiring code? How do I pass payload to the code if it needs to be written using java code.

Answer 1

You can invoke a Webservice inside a bpmn.

You can create a Task of type Service, and choose in Properties/Details/Implementation: Connector.

Next you configure Connector properties, setting:

Connector Id: http-connector (for rest json webservices) and Input Parameters:

• url (e.g. http://localhost:8080/client?id=12
• method GET/POST
• headers type MAP: Accept application/json...

You receive the webservice response as Process Variables, configuring the Output parameters as follows :

• response, type text, value ${response}
• returnCode, type text, value ${statusCode}

Hope this helps you

For start: please note that camundas claim is "developer friendly". It's never been the goal of camunda components to just "click together" a working process. If you are looking for such a solution, you should a) have a look at the zero coding myth and b) maybe choose another tool.

That being said, check out the camunda-connect framework, introduced with 7.2, it should do what you need (though it involves xml coding).
