GET /sapi/v1/rebate/taxQuery API is not working

The tax rebate API is not working and always giving this response.

{“code”:-1000,“msg”:“System abnormality”}

Try it with startTime and endTime parameters and see if it fixes the issue.

Thanks for your message. On giving startTime and endTime, I am getting this response.

{“code”:100001003,“msg”:“Verification failed”}

What does this mean?
