The Latitude Learning LMS uses PayPal to process credit cards. After upgrading your LMS to include e-commerce, you need to setup a PayPal Website Payments Pro account.
To setup a PayPal Website Payments Pro account, first establish a PayPal account. After your PayPal account is setup, upgrade it to Website Payments Pro (which involves further bank account and business verification steps by PayPal). Here’s a link to that info: https://www.paypal.com/webapps/mpp/website-payments-pro. Please note: it typically takes PayPal 1-2 business days to process a Website Payments Pro upgrade request and create your PayPal Website Payments Pro API credentials.
Once PayPal creates your credentials, enter them into your LMS on the LMS Information page. To get to the LMS Information page, login as an administrator, click on Site Management in the left column, then click on LMS Information.
