Once you have created your form and added fields, you can create a feed for Windcave. Feeds tell the add-on what to send to Windcave when someone submits a form. You create Windcave feeds under the Form Settings menu for the form.
The first set of fields lets you select how your form sends information to Windcave. Give the feed a meaningful name, and select whether to send your transaction to the Live or Test gateway.
Each field in the form that should be sent to Windcave needs a mapping. You can select the Gravity Forms field from a list of fields next to each Windcave field; see the example below.
The hosted page section of the settings lets you delay some Gravity Forms actions until after a transaction, and whether customers can retry their transaction if it fails.
