Section 1

Integration is often the fastest modernization win

Many IBM i teams do not need a complete application rewrite to make meaningful progress. They need cleaner connections between IBM i data, customer portals, analytics tools, shipping platforms, or mobile workflows.

That makes API work one of the most practical modernization levers available.

Section 2

Choose the first use case carefully

The best first API project usually has visible business value, manageable risk, and a clear owner. Buyers should avoid broad platform ambitions before one useful flow is working well.

Smaller wins help teams build confidence and governance habits.

Section 3

Integration quality depends on operational design

Monitoring, retry handling, data ownership, and access control determine whether integration projects age well. Buyers should judge tools by how cleanly they support those realities, not just by connector count.
