Next, set up the data that you want to send over to your action app.
In this step, you'll see dropdown menus and/or form fields to fill in. Some are required, while others are optional. Different fields accept different types of data—for example, dates, text, or numbers—and there are three different fields types that may appear:
Dropdown menus: click the down arrow to select from a list of options.
Text fields: enter a value, or map data from previous steps. To map data, click the dropdown menu and select a variable from the list.
For example, if you're setting up an action to upload new Gmail attachments to Dropbox, you would map the attachment file from the trigger (New attachment in Gmail) to the action.
List fields: collections of text fields that let you send multiple values over. To send more than one item, click the empty field below the current field.
After filling in all required fields and any optional fields, click Continue to move to the final step.
Each action step has a limit of 1,000 fields. This includes fields like Name and Email Address that are standard in your app and custom fields that you create in your app.
