Use standard idempotency key header #239

Open nickevansuk opened 1 year ago

nickevansuk commented 1 year ago

Idempotency is currently achieved for B using the UUID, however a more standard approach should be adopted to ease implementation with existing libraries and frameworks.

If this is still in draft by the time it is considered for inclusion in the spec, suggest using x-idempotency-key in line with Open Banking, rather than using the draft before it is ratified.

I'd recommend just using the actual header. Migrating header names can be a pain, and it's recommended to not use the X- prefix any more.
