RelayWarden
Reliability where it matters

Payments, shipping, SaaS, and APIs.
One place to recover.

RelayWarden gives every critical event a durable path between “sent” and “handled,” whether the source pushes or you need to pull.

For e-commerce teams01

Payment notifications

Search all your payment gateways at once from eCommerce up, then open the complete history behind any order. One confirmation arrives; RelayWarden keeps it durable, forwards it byte-for-byte, and shows whether the shop updated.

For operations teams02

Shipping and operations

Give fulfillment, shipping, and internal services one observable delivery path. Per-project queues keep a noisy sync from holding up payments while retries absorb warehouse downtime or a partner outage.

Unexpected downtime

A failed deploy, expired certificate, DNS incident, or overloaded worker should create a backlog, not lost business. RelayWarden keeps the event safe, paces recovery, and shows exactly what happened.

High-volume webhook bursts

Withstand bursts without crashing systems. RelayWarden absorbs traffic into durable queues, then controls delivery concurrency so recovery does not overwhelm the services receiving it.

The customer paid.
The shop never got the message.

After a payment, Redsys tries to tell the shop that the payment was made. During broad anti-piracy blocks linked to LaLiga matches, internet providers block addresses shared by many Cloudflare websites. The block cannot tell those sites apart, so Redsys’s confirmation can be stopped before it reaches the shop, even though the shop itself blocked nothing.

“The payment went through. The confirmation did not.”

Shared IP
Nothing arrives
The payment is accepted, but the confirmation dies at a blocked shared address. The order stays pending, and no one is told. The customer is left waiting, and it ends up costing time and money in support tickets and complaints.

Our endpoints use redundant AWS infrastructure, IPs that are not shared with other AWS customers, plus our own TLS termination, so ECH cannot become a problem. Either way, if the shop can’t answer, we keep the message, retry, and let you know.

For agencies06

Agencies and portfolios

Standardize reliability across client shops. When one client’s hosting goes down, its backlog stays isolated while the rest of the portfolio keeps delivering.

First-party analytics

Dispatch mode proxies first-party beacons through your domain when ad blockers drop third-party requests. Intentionally direct, single-attempt, and short-lived.

For product teams08

SaaS and CRM events

Keep lifecycle events, subscription changes, and CRM updates moving through deploys, restarts, and queue incidents without rebuilding delivery logic per vendor.

Your SIEM, fed on schedule,
even when nothing pushes.

Not every source can push. The SIEM puller polls external APIs on a schedule, cursors through new records, deduplicates, and ships to one SIEM, or several at once, with the same history and alerts as any relay.
