Send it again unchanged?No — change something first
.NET SDKIdempotencyConflictException

What it means

This operation id was already used with a DIFFERENT order body. This request was not placed. The order stored under that id is untouched — and if you were resuming it, it may have completed.

What to do

  • If you meant to resume: send exactly the body you stored with that id — same card, quantity, prices and reference.
  • If this is a genuinely new purchase: use a new operation id.
  • One id must always mean one purchase with one body.

Where you can meet it

Example

The body of the refusal. Its type is the address of this page.
