  2. *HTTP Request Method - Select the request method which will be used to access a third-party application. It is recommended to use the POST method if the URL is very long or has some non-ASCII characters. Use GET if the target form is idempotent (usually a pure query form).

  3. *Activation Criteria - Indicate the activation criteria as a value or use regular expression. For example, ^\[0-9]$, which means that if server response is an integer from 1 to 9, it satisfies indicated expression. If a response from the remote server matches indicated criteria, the survey or form will be served to respondent. This parameter cannot be empty.

For instance, FF_01=Q1.A1, where FF_01 is the arbitrary unique name of the parameter you are sending data to, Q1.A1 is the parameter value which gets data from the survey question. To use send multiple parameters use the following syntax: FF_01=Qx.Ay&FF_02=Qx.Ay.Cz

  5. *Alert Message - If a response from the remote server does not match the Activation Criteria, this message will be displayed to survey or form respondent.
