Adding Dynamic Endpoints¶
You cannot dynamically construct the back-end endpoint of an API using the address endpoints in the WSO2 API Manager. To achieve the requirement of a dynamic endpoint, you can use the default endpoint instead.
The default endpoint sends the message to the address specified in the To header. The To header can be constructed dynamically. For example,
<sequence xmlns="http://ws.apache.org/ns/synapse" name="default-endpoint-seq"> <property name="service_ep" expression="fn:concat('http://jsonplaceholder.typicode.com/', 'posts/')"/> <header name="To" expression="get-property('service_ep')"/> </sequence>
In this example, you have constructed the
service_ep property dynamically and assigned the value of this property to the To header. The default endpoint sends the message to the address specified in the To header, in this case,
For more details about working with dynamic endpoints, see Endpoint Types.
You can copy the content of the above sequence to an XML file and upload it to an API configured with a dynamic endpoint using the Publisher Portal UI.
