Streamlined tools and processes allow analysts to quickly define and share mappings between messages.
api-map suggests matches between message elements based on powerful machine learning heuristics.
api-map helps catch mis-matches between data types and missing mandatory fields earlier.
api-map uses message schemas like XSD and JSON Schema to define mappings, so specifications are firmly tied to implementation.
A shared online tool means you're never working from an out-of-date document. You can tag fields and mappings for review by analysts.
A machine-readable mapping format allows you to generate the boring bits, and focus on the parts only a developer can do.
Visually tracing data elements through multiple transformations allows you to quantify your testing effort.
Because integration is not directly visible to the end-user it is often not well documented. Clear integration documentation from api-map gives you a concrete, versioned artifact to verify against.
