Classifications

Create Classification

Create a classification dimension used to tag and analyze transactions across multiple dimensions.

Headers

Idempotency-Keystring

Optional. A unique value (a UUID works well) identifying this operation. If the request is repeated with the same key, the original response is replayed instead of the operation running again, so a retry cannot create a duplicate record. Results are replayable for 48 hours. Reusing a key with a different request body returns 422.
