Automatic Failover to PayPal
Primer
Automatic failover is the core reason large merchants buy an orchestration layer instead of relying on one processor. When checkout traffic can jump from Adyen or Stripe to PayPal without a new integration or customer reentry, the merchant turns processor outages and issuer specific failures into a routing problem inside one control panel. That protects conversion, and it also lets the payments team keep tuning for cost and approval rate by market while preserving a live backup path.

Primer packages this as Fallbacks, where a failed or declined payment is retried on a backup processor, with recovered volume and events visible in the dashboard. Primer also says merchants can activate backup processors in workflow configuration rather than rebuilding checkout logic in code.

This workflow matters because major PSPs still optimize mainly inside their own stack. Adyen sells routing and retry tools, and Stripe now offers orchestration and retry routing in private preview, but both start from the position of being the primary processor. Primer sits above them and treats each PSP as one interchangeable endpoint in the flow.

The backup is not just for full outages. In practice, merchants use it for softer failures too, like higher decline rates in one region, a processor missing a needed feature, or a payment method performing worse than expected. That is why orchestration vendors compete on rules, monitoring, and speed of switching, not just on raw integrations.
The next step is that failover becomes always on optimization instead of emergency insurance. As Stripe, Adyen, and PayPal add more orchestration features, the control point that wins will be the one that gives merchants the fastest way to test routes, measure approval lift, and shift volume instantly across processors, payment methods, and geographies.
