Dutch software architect. Built multi-tenant carrier middleware for 1k+ shippers; advocates idempotency and good logs.
Carrier APIs with latencies above 550ms consume dangerous chunks of response time windows, with some spiking above 1.2 seconds during peak periods. Yet most architectures today run cold caches that force users to wait for fresh carrier calls on every rate request or tracking lookup. Edge computing reduces latency
When your multi-carrier integration platform starts handling thousands of requests per second across FedEx, UPS, DHL, and regional carriers, traditional rate limiting breaks down. The culprit? In a distributed environment, the "read-and-then-write" behavior creates a race condition, which means the rate limiter can at times be too lenient.
The perimeter fell years ago. That firewall protecting your carrier integration platform? 84% of security professionals experienced API security incidents in 2024, up from 78% in 2023. When your platform handles FedEx webhooks, DHL rate shopping, and UPS tracking calls for hundreds of tenants, you can't rely on
Your multi-carrier integration just silently started rejecting label requests from DHL Express. No error alerts fired, no circuit breakers tripped, and your monitoring dashboards show everything as green. What was going on? Turns out, the carrier had made what is called a "breaking change" in their API, and
CAMARA aims to move telco networks away from point-to-point integrations and ad-hoc APIs on specific technology stacks to generic, abstracted, and common APIs — but shipping and logistics platforms face identical challenges. With the CAMARA project now counting 396 companies and 1,100+ contributors, delivering 25 APIs across 13 sub-projects that
When the busiest ordering week arrives and your carrier experiences an outage, you're left unable to calculate shipping rates and customers aren't impressed. This scenario plays out repeatedly across carrier integration platforms, but the real culprit isn't usually a simple outage. The problem starts
UPS replaced its entire existing API infrastructure, deprecating access key-based authorization in favor of OAuth 2.0 security models, with post-June 3, 2024, any transaction with UPS mandating this new OAuth security model. Major carriers are actively migrating away from SOAP-based APIs, with FedEx retiring their legacy Web Services in
Your FedEx integration responds in 200ms on average. Your local courier API takes 5 seconds. DHL varies between 1 and 15 seconds depending on the time of day. Yet most carrier integration middleware still uses static timeout values across all providers. Between Q1 2024 and Q1 2025, average API uptime
Major carriers are shifting away from SOAP-based APIs to event-driven architectures faster than most carrier integration platforms can adapt. UPS, FedEx, USPS, and DHL are all migrating from XML based APIs to oauth JSON "REST" (not actually restful) APIs. Meanwhile, AsyncAPI 3.0.0 - is now available
Your carrier integration middleware is only as reliable as its weakest API dependency. Average API uptime fell from 99.66% to 99.46% between Q1 2024 and Q1 2025, resulting in 60% more downtime year-over-year—approximately 10 extra minutes of downtime per week and close to 9 hours across a
UPS replaced its entire existing API infrastructure, deprecating access key-based authorization in favor of OAuth 2.0 security models, with post-June 3, 2024, any transaction with UPS mandating this new OAuth security model. FedEx announced on August 18, 2022 that previous FedEx Web Services WSDLs are heading for retirement, giving
Carrier webhooks fail at rates that would bankrupt a traditional SaaS platform. The business costs of webhook failures can be substantial, including lost sales, customer dissatisfaction, regulatory penalties, and operational disruption costs, and in carrier integrations, these failures happen far more frequently than other domains. The numbers tell a harsh
