Test REST activity template inputs You can test the input parameters of a custom REST activity during its development without having to run the activity in a workflow context. About this task This test executes only the input parameters against an endpoint and not the pre-processing or post-processing scripts. It is not necessary to check out the activity to test it. Procedure Complete the fields in the Inputs tab of the activity designer. You can either create input variables and map them to fields in the form or provide actual values for these fields.Note: Make sure to define an appropriate MID Server. The test fails if the MID Server cannot be found or if it cannot connect to the target. Click Test Activity. If you added actual values for your parameters and fields, the system runs those values against the specified target and returns the resulting payload. If you mapped input variables to fields and parameters, the system displays a dialog box for assigning test values to those variables. In this example, the stock symbol name in the REST activity is a variable. Provide test values, if necessary, and click OK to display the payload. The Response form appears, providing different views of the payload. The tabs display the activity's post-processing parameter values. The entire payload appears in the Raw Output tab, allowing you to copy the contents into the clipboard. Click the X in the upper right corner of the window to close it.
