Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Mercado Pago
Provides access to Mercado Pago Marketplace API.
checkout-com-webhooks
Receive and verify Checkout.com webhooks (checkout.com — the global payments processor: card acquiring, APMs, disputes, payouts, issuing). Use when setting up a Checkout.com webhook handler, debugging Cko-Signature verification, or handling events like payment_approved, payment_captured, payment_declined, payment_refunded, dispute_received or fraud_reported. Checkout.com signs with HMAC-SHA256 over the RAW body, hex-encoded, in the Cko-Signature header, and can optionally send a static Authorization header key. Not Checkout Page (checkoutpage.com), not CheckoutJoy, not 2Checkout / Verifone, not Stripe Checkout, not Shopify checkout webhooks.
