How to create customer-specific FIX specifications, and why?

What are customer-specific specs, and why might they be useful for you?

Here at FixSpec, we think of API documentation as a "contract" between two parties. It describes available messages, fields, and enumerations and workflows. It tells readers that if they send X in, they can expect Y in return.

Customer-specific specs take this a step further by removing anything that a specific customer doesn't use, and extends the documentation to capture bespoke customisations and transformations. This has a number of benefits to both the sender and receiver.

In this episode of #doFIXdifferently, Chris Lees explores what customer-specific specs are, how you can go about creating them, and why this is worth your time.
