From enabling agentic purchases of Amazon items with stablecoins to purchasing NFTs using Apple Pay, Crossmint Checkout supports a wide variety of permutations - multiple asset types, payment methods, integration approaches, and advanced configuration options. This guide helps you make the key decisions for your integration.

​
1. What asset type are you working with?

Understand which asset type you will be purchasing or enabling the sale of.

Over 1 billion products and services from Amazon, Shopify, Flights, and more.

Memecoins

​
2. Choose an integration modality

Crossmint checkout can be integrated into your application in four different ways, ranging from a bare metal headless API with maximum UI flexibility, to a no-code payment link solution.

3. Choose payment method(s)

You can choose multiple options from the following payment methods to include. Consider the following as you decide:
  • Is your audience crypto-native or mainstream consumers familiar with fiat payments?
  • What level of optionality do you want to enable? Adding many methods may add complexity during a user’s checkout flow.

​
4. (For digital purchases) How do you want your users to receive their item?

Choose one or both: decide how users can choose to receive their purchased assets.
  • Consider if your users already have crypto wallets or if they are new to crypto.
  • Adding more options for delivery methods adds complexity to your checkout experience.

Wallet Delivery

Send to their crypto wallet address

Email Delivery

Send to their email. Crossmint will create a wallet for the user that they can later log in to.
How to set it up by integration modality:
  • Hosted checkout: You can specify the recipient by adding a mintTo property to the button component. Refer to the Specify Recipient guide for more information.
  • Embedded checkout: You can choose to hide the delivery options from the user. Refer to the UI Customization guide for more information.
  • Headless checkout: You can set the recipient to an email address in the API call, or by setting the destination to a wallet address and including a receiptEmail property within the payment object. Refer to the Quote Phase guide for more information.
