Add New Item - POST
If you choose POST, you will need to add the input fields you want - this is because the platform/app is not pulling any data from the REST server.
On the REST Service URL step of the wizard, after choosing POST, you can enter your REST URL.
Check "Include Custom Headers" if needed and you can add as many key/value pairs as necessary. (If you're not sure if you need this, check with your REST database administrator)
Pass Through Variables
The Pass Through Variables section allows you to include data from other pages in your POST. For example, let's say you are creating an employee directory separated by department. The app user will see a list of departments, tap one, and then see a list of employees in that department. From here, you want the app user to be able to add a new employee. You could let the app user select the department by adding it as a Form Field (see below), or you could set the department automatically by using a Pass Through Variable. In this case, you could name the variable something like "departmentId". Enter a valid sample value, which will be used if you do a test POST (see below). You can add as many Pass Through Variables as you want.
**NOTE** When you are targeting your POST page, you will need to specify a variable to use for each Pass Through Variable.
The Form Fields section is where you can add your input fields - these are the fields the app user will enter.
Be sure to enter the Database Name correctly for each field. Enter a Sample Value for each field - these are the values used if you click the blue "Send" button to do a test POST. Below that, you will see the response from the REST server - if everything is correct, you should see "200: The request has succeeded." Depending on the REST server, it might also return the data you just entered.
You do not have to do a test POST, but it can be a useful check to make sure everything is working correctly and all variable names have been entered correctly.
