How to Monitor Your Payment Stack: Stripe, Braintree, PayPal, and Adyen

Every third-party outage has a cost. But payment processor outages are different: they have a direct, immediate, calculable revenue impact. When Stripe is down, checkout breaks. Broken checkout means lost transactions — not delayed transactions, not slightly worse transactions, but transactions that never happen. Cart abandonment after a payment failure is 15 to 30%; most of those customers don't come back.

This directness makes payment monitoring the highest-ROI category of third-party monitoring. The calculus is simple: how many transactions does your application process per hour? How much is each worth? A 30-minute payment processor outage during peak hours, multiplied by your abandonment rate, gives you a concrete cost figure. For mid-market SaaS companies, that number is typically $5,000 to $50,000 per incident. Against that, the cost of monitoring is trivial.

Payment stacks have also grown more complex. Most companies use a primary processor (often Stripe or Braintree), a backup processor for redundancy (often a different provider), a separate fraud detection service (Stripe Radar, Kount, Sift), and sometimes a separate payment gateway for enterprise customers. Each of these is an independent failure point that needs monitoring.

Stripe is the most widely used payment processor in PulsAPI's user base and historically maintains strong uptime — typically 99.9%+ over rolling quarters. But 99.9% still allows 8.76 hours of downtime per year, and Stripe has had notable incidents: a February 2026 partial outage lasting 2.5 hours affected checkout and billing for thousands of businesses.

Stripe's status page exposes multiple components that can fail independently: the Stripe API (affects all Stripe-dependent operations), Stripe Dashboard (affects your team's access but not necessarily customer-facing flows), Stripe Checkout (affects hosted checkout sessions), Stripe Billing (affects subscription management and invoicing), and Stripe Radar (affects fraud detection — often still processes payments but with reduced fraud protection).

Subscribe to each Stripe component separately in PulsAPI. A Stripe Dashboard outage may not affect your checkout flow at all — don't page on-call for it. A Stripe API or Checkout outage affects your revenue directly — page immediately. Configure this distinction in your alert rules: Stripe API/Checkout → PagerDuty Tier 1, Stripe Dashboard/Radar → Slack notification only.

Braintree (owned by PayPal) is a common secondary processor for teams that use Stripe as primary. In Q1 2026 data from PulsAPI, Braintree recorded 99.97% uptime — outperforming Stripe's 99.89% over the same period. Monitoring Braintree's status matters both as a backup path and because many enterprise customers have payment routing through Braintree specifically.

PayPal has a more complex monitoring profile: multiple consumer and business products with independent status, including PayPal Checkout, PayPal API, PayPal Invoicing, and Venmo. If you accept PayPal as a payment method in your checkout, subscribe to PayPal's API and Checkout components — these are the ones that affect your customer-facing flows.

Adyen is the preferred processor for enterprise SaaS and marketplace platforms due to its global coverage and multi-currency capabilities. Adyen generally maintains high uptime but has had regional incidents. Subscribe to Adyen in PulsAPI and configure region-specific monitoring if your Adyen processing is tied to specific geographic Adyen nodes. Enterprise Adyen contracts typically include direct status communication — but PulsAPI's monitoring catches degradation before official acknowledgment.

Real-time payment stack monitoring is most valuable when paired with a tested fallback strategy. Monitoring tells you immediately when your primary processor has an issue; your fallback strategy determines what happens next.

The most resilient architecture maintains two active payment integrations: a primary (where all new transactions are sent by default) and a secondary (available for failover). Your payment routing layer checks PulsAPI's status for your primary processor before routing each transaction — or better, subscribes to a webhook from PulsAPI that signals status changes and updates routing configuration automatically.

For teams that cannot implement dual-processor infrastructure, a graceful degradation mode is the minimum viable fallback: when the primary processor's PulsAPI alert fires, display a 'Payment processing is temporarily unavailable — we're working on it' message on checkout, halt new transaction attempts to prevent failed charge accumulation, queue subscription renewal retries for execution post-recovery, and post a proactive status update. Teams that implement graceful degradation before a major payment incident — not scrambling to build it during one — consistently report significantly better customer outcomes and lower support volume.
