Camunda Connector Reference
Camunda Connect provides a simple API for connecting HTTP services and other things. It aims at two usage scenarios: usage in a generic system such as the Camunda BPM process engine and standalone usage via API.
Connectors
Camunda Connect provides a HTTP and a SOAP HTTP connector. If you want to
add an own connector to Connect please have a look at the extending Connect
section. This section also describes the usage of a ConnectorConfigurator
to
configure the connector instances.
During the request invocation of a connector an interceptor chain is passed. The user can add own interceptors to this chain. The interceptor is called for every request of this connector.
connector.addRequestInterceptor(interceptor).createRequest();
Maven Coordinates
Connect can be used in any Java-based application by adding the following maven
dependency to your pom.xml
file:
Camunda BOM
If you use other Camunda BPM projects please import the Camunda BOM to ensure correct versions for every Camunda project.

Camunda Connect is published to maven central.
Logging
Camunda Connect uses camunda-commons-logging which itself uses SLF4J as
a logging backend. To enable logging a SLF4J implementation has to be part of
your classpath. For example slf4j-simple
, log4j12
or logback-classic
.
To also enable logging for the Apache HTTP client you can use a SLF4J
bridge like jcl-over-slf4j
as the Apache HTTP Client doesn’t support
SLF4J.
