Error Code

Introduction to FR24 Error Code Structure#

Our error codes consist of 8 digits. Below is the structure diagram of our error codes:
image.png

First Digit: Error Source#

Defines the responsible party for the error (1, 2, or 3):

Example: 10101115 - "[Request Error]:Invalid RBD (cannot be empty);For request ERROR resolution, please check your request parameters or format. If the error message from FR24 is unclear, please contact FR24 team for support."
Typically indicates parameter issues that can be resolved using the returned message
2: FR24 system issue
Example: 20933232 - "[Unexpected Search Response]:FR24 has no available offers for this route;For FAILED resolution, FR24 has logged and followed this fail type, including this case. For CRITICAL impact or repeated occurrence, please contact FR24 team."
We will actively resolve such issues
