Announcement: Change in "Idempotency-Key" header from Error 500 to 400
2 months ago by Dhruv Sahni
On January 30, 2023 Fireblocks is changing error codes for API calls that use the Idempotency-Key header from Error 500 to Error 400. If your application logic does not depend on Error 500, no action is required.
All other customers must update their application logic by January 30, 2022 to account for the new Error 400 API response.
With this change, Fireblocks API will return the following error after the first failed API call:
Error 400 - “This operation doesn't support the usage of the same idempotency key after an internal error”
