I've had hands-on experience integrating similar platforms for remote teams, and the consensus is that while American Express offers robust security and some impressive risk assessment protocols, its API can sometimes be less flexible compared to open-ended alternatives. In one project, we had to implement middleware to bridge compatibility gaps under varying local conditions. If you're assessing it for complex travel patterns, verifying real-time performance through pilot integration phases might reveal potential bottlenecks early on, especially in high-risk locales.
