In your WordPress admin, go to Simple Pay → Settings → Stripe Setup. Click the “Connect with Stripe” button to connect WP Simple Pay to your Stripe account.
You’ll be taken to Stripe.com where you’ll be prompted to either create a new Stripe account or log in to your existing one.
Once you complete this process, you’ll be taken back to your website’s Stripe Setup tab.
On the same tab is the Test mode toggle. We highly recommend staying in Test mode until you’ve completed setting up your payment forms. Read more about using Test mode.
Now it’s time to create your first payment form.
Disconnecting from your Stripe Account
If you need to disconnect from Stripe for whatever reason (to connect to a different Stripe account perhaps), in your WordPress admin go to Simple Pay Pro → Settings → Stripe Setup.
Find Connection Status then click disconnect this account. You should see something very similar to this:
Once you have done that, you should once again see the Connect with Stripe button and are free to connect to another Stripe Account.
