The eventquestions API allows you to create Dispatch Questions.
To do so, you'll need 6 parameters:
API Key: A valid authorization key for that site.
site: The Site ID #.
question: The question you want to posed on the Dispatch.
answer_choices: The answers for selection in the Dispatch. You can provide more than one selection by putting a comma (,) between the choices.
ask_when: This is an integer. 1 is on open, 2 is on on close, 3 is on complete.
priority: This is also an integer. It will display the number sent in in the order of which you want the questions asked.
