If you are using the webpage to generate a disclosure for a customer, switch both “Production Salesforce” and “Production IL Shines APIs” on.
Production IL Shines APIs
If you are doing extensive testing, don't switch this on. Note that the test IL Shines APIs don't email the disclosures. If you do want to test that functionality you can check that box.
Simulate September 3rd Changes
If you are testing the changes that will go live on September 3rd, switch this on.
