The USPS Web Tools API platform shut down on Sunday, January 25, 2026, and FedEx's remaining SOAP-based endpoints will be fully retired in June 2026. If you're reading this and still haven't migrated, you're already in damage control mode. Over the past
Most teams discover the hard truth about carrier API test harnesses during their first production month, when 72% face reliability issues that never appeared in sandbox testing. Your test suite passes every scenario, latencies look acceptable, and rate limits seem manageable. Then production traffic hits, and FedEx starts throwing 429s
The recent CVE-2026-21858 affecting the n8n workflow automation platform shows exactly why webhook testing production requires more than development-level validation. A critical vulnerability (CVE-2026-21858, CVSS score 10.0) was disclosed affecting the n8n workflow automation platform, allowing attackers to remotely execute code and fully take over vulnerable instances without any
When handling over 400 shipments per hour, even a single second of latency per package creates backups cascading down the conveyor, leading to operational delays, overtime, and SLA failures. For instance, an enterprise retail customer utilizes an autoboxing solution that spits out 400 shipments per hour, or just under 7
By February 1, 2025, all public apps using deprecated product and variant REST API endpoints must migrate to GraphQL, with custom apps following by April 1, 2025. But here's the catch that makes this deadline particularly brutal: B2B e-commerce migration spending is projected to hit $36 trillion by
February 3, 2026 marks a hard cutoff for ICS2 integration challenges across European customs systems, with only message version 3 accepted after that date. ENS filings lodged in version 2 before this date cannot be amended afterward - they must be invalidated and completely re-filed in version 3. Your integration
Most integration teams discovering FAPI 2.0 implementation aren't prepared for the infrastructure reality check that comes with sender-constrained tokens. Both UPS and FedEx moved to OAuth 2.0 authentication by 2024, but many standard web servers reject headers larger than 8KB by default. Here's what
Your UPS account just threw another authentication error. FedEx is demanding certificate renewal again. DHL's regional API keys are scattered across three different test environments. Sound familiar? The carrier integration landscape is shifting under our feet. In 2024 most of the shipping carriers migrated to oauth based authentication
Over 61% of organizations are now using GraphQL, yet most carrier integration teams stick with REST without understanding the performance implications. After testing both approaches across DHL, UPS, and FedEx APIs, we've gathered concrete data on which architecture delivers better results for shipping operations. The choice between GraphQL
API downtime surged by 60% between Q1 2024 and Q1 2025, with average uptime dropping from 99.66% to 99.46%. This translates to approximately 10 extra minutes of downtime per week and close to 9 hours across a year. For carrier integration teams managing multi-carrier shipping APIs, this isn&
API authentication has become a battleground. Between Q1 2024 and Q1 2025, average API uptime fell from 99.66% to 99.46%, resulting in 60% more downtime year-over-year, while 99% of organizations experienced API security issues in the past 12 months. DORA fully applies from 17 January 2025, and the
European shippers learned October 2025's lesson the hard way. While your application monitoring tools registered healthy systems and normal CPU usage, customers couldn't check out. 72% of implementations face reliability issues within their first month of production deployment, and between Q1 2024 and Q1 2025, average
