If you are using the ECOM Module in RocketFusion, you need to get the "test" and "live" API keys for the merchant gateway you intend to use. RocketFusion supports Stripe, PayPal, and Authorize.net.
All three merchant gateways use a pair of API keys (essentially account number and password) for both "test" and "live" mode. We generally set up test keys first and run a few fake purchases to make sure the gateway is working, then flip to live mode.
Getting Ready to Copy / Paste the API Keys
RocketFusion has a "settings" page that can show all settings for every module as well as other aspects of your website. We will focus on the ECOM Module settings, here.
First off, of course, log into your website as the administrator.
Mouse-over the rocket icon in the very top left of your screen to get to the Admin Panel
Click on Site Settings, down near the bottom
Click on ECOM in the first column of links
In the list of settings, you'll want to focus on the ones shown in the image on this page:
Ecom Merchant (Stripe, PayPal, Authorize.net)
Ecom Merchant Mode (Live, Test)
Ecom Merchant Live Key 1 and 2
Ecom Merchant Test Key 1 and 2
For Ecom Merchant, choose the gateway you're going to use
Set Ecom Merchant Mode to Test for now
Copy and paste the API Keys (see below) to Live and Test Key 1 (public key / account) and Key 2 (secret key / password)
Obtaining PayPal API Keys
PayPal allows for the use of API keys only on Business accounts. If you are using a Personal account you will likely need to upgrade your account to Business, which is also free.
In a new browser tab, go to PayPal.com and log in using your regular username (email address) and password
From the Homepage on PayPal, click the Developer link on the top right
Mouse-over your name on the top right and click My Account
On the left side bar, click the top link My Apps & Credentials
Click the white "Live" link in the pill near the top of the page
Alternatively, you can also create a "Sandbox" set of keys for testing while we're still working on your site
If you do create a sandbox set of keys, paste them into the Ecom Merchant Test Key 1 & 2, below
Click the blue Create App button
Enter "RocketFusion API" in the App name field, then click the blue Create App button
On the next page you will be presented with the Client ID. Copy that string to your clipboard
Return to the browser tab with your website
Make sure you're still on Admin Panel > Site Settings > Ecom
Scroll down to Ecom Merchant Live Key 1 and paste the string in
Click back to the browser tab for PayPal
Click the "Show" link under Secret:
Copy the secret string to your clipboard
Click back to the browser tab with your website
Paste the string into Ecom Merchant Live Key 2
Scroll up near the top of this page and ensure Ecom Merchant is set to PayPal
