Setting up the parameters for the Data Mapping is extremely easy. You simply enter a parameter name and then map it to a specified field.
You may also map to a static value set to your standards. Simply input the parameter name, set the Map to Field to Static Value, and input the static value to the right.
Additionally, you may click the cloud button and paste a Posturl into the cloud and it will automatically insert the data mapping based on the Posturl.
