If you host your own website and are a developer or if you’re working with a developer, Square’s E-Commerce API is great option to streamline all your sales channels.
If you don’t have access to developer resources, Square’s App Marketplace offers a wide range of partner applications that work with Square. Build your website, manage your items across sales channels with ease.
How does E-Commerce API work?
Square’s E-Commerce API is payment solution that allows you to accept credit and debit card payments from your own website. Connect your website to Square with an E-Commerce API application, and without ever leaving your website, customers can securely make online purchases. Payment processing is completed entirely through Square, so you’ll never need to handle sensitive payment card data. You can view your sales activity on your online Square dashboard, and deposits are sent to your linked bank account.
What cards are accepted with Square’s API?
You can use Square to accept payments from any cards with the Visa, Mastercard, American Express, Discover, JCB, or UnionPay logos. You can also accept any gift card or prepaid card with the same logos mentioned above, as long as the amount of the charge does not exceed the balance on the card.
Every card has the same flat rate. Corporate, prepaid, gift cards, and rewards cards have no additional fees, and debit cards are run just like credit cards (you do not need to enter a PIN).
What’s the difference between Square’s eCommerce API, Square Checkout API and eCommerce partner solutions?
Checkout API: Square Checkout API lets merchants accept online payments for supported payment types using a checkout workflow hosted by Square, simplifying the process of accepting online payments. Once it’s time to collect the payment, buyers enter Square’s hosted checkout flow and return back to your website once the payment is complete.
E-Commerce API: Square’s E-Commerce is a payment solution that allows you to accept credit and debit card payments from your own website. Customize your own payment form and checkout experience to accept payments with Square.
Square Integrations: With our partners – Wix, Weebly, Bigcommerce, Ecwid, WooCommerce, and more – you’re able to seamlessly integrate online payments with your Square account and process orders directly from your partner-hosted E-Commerce website. No need to enlist help from a developer, simply connect your website to Square with a few clicks.
Is E-Commerce API a good fit for my business?
If you’re a Square merchant and you are building a mobile checkout or hosting your own website, the API is a great option to streamline all your sales channels. We recommend working with a website developer to get set up. If you don’t have access to developer resources, we encourage you to visit Square’s App Marketplace.

What is a personal access token?
This is a code your application uses to communicate with Square for processing payments. If you’re working with a trusted developer, you may want to share your personal access token to help create your API application. Keep in mind that your token is sensitive account information, similar to your Square account password. If you offer your developer your token, they will have access to make changes to your account information.
Can I accept payments with Square from my Squarespace website?
Although you are unable to link Square directly with your Squarespace website, Squarespace developers can embed Ecwid to accept payments with Square.
