Continuing our previous posts on Custom API

Here we will look at the CustomAPIRequestParameter entity.

  • This entity can be used to define input parameters to the Custom API.
  • It is not a mandatory entity for Custom API i.e. we can define a custom API without any input/request or output/response parameter.
  • In the case of multiple parameters, ordering is not important as they are identified using the name.
  • One parameter can be associated with only one Custom API.
  • We can have multiple parameters with the same Unique Name as long as they are associated with different Custom API.

Say e.g. below is our Custom API

And this is our Custom API Request Parameter associated with the above API of type String

The different data type for the request parameter

Below is our plugin registered for the custom message.

Let us call our custom API

And let us check the plugin trace logs.

We can see the message being called successfully.
