Sample scenario

1. Define the API Flow Properties on the API Flow Properties page.
   • This table shows the information that you must specify on the Request tab:

     Field name	Value
     Endpoint Name	do-while_demo
     Endpoint Path	do-while_demo
     Method	POST
     Resource Name	do-while_demo
     Resource Path	do-while_demo

   • This table shows the information that you must specify on the Request Body tab:

     Field name	Value
     Presence	Required
     Content Type	application/json
     Name	body
     Schema	{ "$schema": "http://json-schema.org/draft-04/schema#", "type": "object", "properties": { "array": { "type": "array", "items": [ { "type": "string" }, { "type": "string" } ] } }, "required": [ "array" ] }
     Example	{ "array": ["first", "second"] }

   • This table shows the information that you must specify on the Response Body tab:

     Field name	Value
     Content Type	application/json
     ApiFlow Response Status Code	200
     Body	"${DoWhile1.output}"

2. Drag a Do-While task into the API Flow and specify the required information on the Do While Properties page.
   • This table shows the information that you must specify on the Properties tab:

     Field name	Value
     Name	DoWhile1

   • This table shows the information that you must specify on the Do While Parameters tab:

     Field name	Value
     Name	array
     Value	${input.body}.array

   • This table shows the information that you must specify on the Conditions tab:

     Field name	Value
     Expression	if ($.DoWhile1['iteration'] < $.array.length) true; else false

   The expression continues the loop if the iteration is less than the array value, otherwise it exits the loop.

3. Drag a JQ Transform task into the API Flow and specify the required information on theJQTransform Properties page.
   • This table shows the information that you must specify on the Properties tab:

     Field name	Value
     Name	JQTransform1

   • This table shows the information that you must specify on the JQTransform Parameter tab:

     Field name	Value
     Name	JSONJQINPUT
     Value	{ "input": "${input.body}.array", "iterator": "${DoWhile1.output}.iteration" }

     This sets the body as having input and iterator to have the values for array and iteration value for the do-while.

   • This table shows the information that you must specify on the JQ Filter tab:

     Field name	Value
     Expression	.input[.iterator - 1]

     This sets the value JQTransform1.output to the value of the array to that iteration position.

4. Add the API task and specify the required information on the ION API Properties page.
   • This table shows the information that you must specify on the ION API tab:

     Field name	Value
     Name	proxy
     Product	EAM_SOAP_webservice
     Operation	Post CustomerApi/httpbin/proxy/anything
     Optional	No

     In this case an Httpbin is used to post a body.

   • This table shows the information that you must specify on the Request Body tab:

     Field name	Value
     Content Type	application/json
     Name	Body
     Body	{"org":"${JQTransform1.output}"}

   • This table shows the information that you must specify on the Output Parameters tab:

     Field name	Value
     Response Content Type	application/json
     Name	response2
     Response Type	BODY

This screenshot shows how the full API flow should be:

To test this, send an array. For example:

{
	"array": ["first", "second", "Third", "Fourth"]
}

In the result there should be four iterations with JQTransform Output and ION API Response2 output.
