Step 1: Request your API key from your NGP
You'll need to select "RUN! (Designed To Run)" from NGP's integration list on their site. If you can't find it, you can manually request an API key from your NGP account rep.
Note: API keys they've given you for other services will not work for Run, so you'll need to request a new one.
Step 2: Enter your NGP information on Run
On the Run form builder, click to add destination, and then enter BOTH your NGP API key and your main NGP account email. Confirm that it's connecting correctly under Status after you save.
Step 3: Select NGP as the destination on ALL forms you plan to use
On the Run form builder, you must click on the Enable checkbox to the left of the destination for all forms you want to use this destination for on the site.
Add Source Codes
Source codes can help you track your submissions in NGP, so you know where they come from. There are two steps to adding a source code to an NGP account.
Add a Source Code in your NGP control panel.
On the Run form builder, select a Source Code from the Segments column.
Custom Fields
Custom fields must be created on your NGP VAN account directly.
In order to add custom fields to your form, open your Run form builder, click Add Form Field, and add a Custom Field (like 'text' for example). Under the NGP custom fields column, Run will pull down a list of your custom fields from NGP to select from.
