# Implementation Tests

### Kotlin Example Project

To verify that Pay Monthly is functioning properly during checkout, please use the following traveler profile and credit card information. Kindly recall that the lion’s share of traveler profile information will be carried over from whatever the traveler has entered into a website’s native checkout forms, so it is critical to test Payments API functionality by simulating the full checkout experience.

#### Profile info for Pay Monthly loan approval/disapproval

Use this [traveler profile and credit card information](/v1/docs/testing-details) to generate an approval, subsequent offer, and confirmation for a Pay Monthly loan application. Aside from the traveler’s name, which is “Arthur” for the approved case and “Emily” for the disapproved (known in the industry as “adverse action”) case, all other information will remain the same.
