Connecting Payment Processors

Connect SamCart with Stripe and/or PayPal to accept live payments.

SamCart isn't a payment processor itself. Think of it as a conversion-driving bridge that connects your customers to Stripe and/or PayPal, the main payment processors that SamCart integrates with.

Connect your SamCart Marketplace with Stripe and/or PayPal by following the simple steps below:

  • From your SamCart Dashboard, click the Gear icon in the bottom left corner of your screen:

  • Next, select the Processors tab (1) on the left-hand sidebar. From here, click on the "Add New" button (2):

  • In the pop-up window, select which Payment Processor you would like to integrate with. We strongly recommend connecting with Stripe first!


When you select Stripe, you're taken to a page where you can either create a new Stripe account, or log in to an existing Stripe account and complete your integration.

If you would like to create a new account with Stripe:

Click the "Setup A New Processor" button on the Processors page.

Complete the form you see on the page, and in just a few minutes, you will have a new account with Stripe, ready to take live payments.

If you already have an account with Stripe:

  • Click the “Sign In” button in the top right corner of the screen.

  • Log in to your Stripe account.

  • Once you are logged in, you will see the following screen. Use the dropdown menu to select which Stripe account you would like to connect with SamCart (if applicable). Click “Connect My Stripe Account” to complete the integration.

  • You will be taken back to SamCart. Your new Stripe integration is now live and will be marked as “Active”.
