Shortcodes
Render the Simpler Checkout button anywhere in your custom pages using shortcodes
If you are an advanced user, you can use shortcodes to control button placement in a more flexible way. Simpler provides two shortcodes :
[simpler-product-checkout]
This shortcode will render a checkout button that will open up Simpler Checkout for the product in the current context. If there is no product in the context (for example in a static page), you can use the product_id attribute to hardcode a product.
[simpler-cart-checkout]
This shortcode will render a checkout button that will open up a Simpler Checkout for the current cart. It is useful for checkout pages, where customers may have added multiple products to their carts.
