We are looking for a solution using Paypal Gateway with Payflow Link using a Secure Token to allow customers to pay payments from a site.  In reading the User's Guide that Paypal provides, the preferred approach appears to suggest using an SDK - see: Payflow Gateway Developer Guide and Reference (paypal.com)

The goal would be for a customer to access a page via the Portal, click on a "Buy Now" type button, then use the Paypal Gateway/Payflow Link to process the payment.  Would think this might be able to setup somehow using JavaScript in the Portal.

The SDK would appear to be more for cases where coding can be done using Java (not JavaScript), so am thinking the SDK wouldn't really be compatible with setup in a Dynamics configuration.

Are there any known guides from a Dynamics persective for setting up connections using Dynamics and Paypal Gateway with Payflow Link using a Secure Token (especially with JavaScript)?  I do see reference on Payflow SDK (paypal.com) that can post transactions directly without the Payflow SDK.
