Taking PayPal payments through your website is a quick and easy way to get started with e-commerce. Evance requires a set of API information in order for it to communicate with PayPal, but finding the information isn't always obvious to those new to PayPal. Here's how to locate the information.
Firstly, if you've not already signed up and logged in to PayPal you should do so before continuing.
At your "My Account" homepage roll your mouse over the Profile menu and you will see "My Selling Preferences" (illustrated below).
Within the "My Selling Preferences" screen you will see a list of options. Click on the "Update" link for "API Access".
If you do not already have API credentials you will need to request them, which is an automated process. Click the applicable link in Option 2, to obtain your API credentials. If the link reads View API Credentials skip to Step 5.
You will be presented with two options and you will require the option labelled "Request API Signature". Ensure that the radio button is checked and then Submit.
Evance will require your API username, API Password and the Signature key.
