Why Is "APIG.0301" Displayed When I Call an API?

Possible causes:

  • "error_msg":"Incorrect IAM authentication information: verify aksk signature fail","error_code":"APIG.0301" indicates that the AK/SK-based authentication failed. Check whether the AK/SK pair is correct and whether the account is restricted due to arrears. For details, see AK/SK Authentication.
  • "error_msg":"Incorrect IAM authentication information: decrypt token fail","error_code":"APIG.0301"indicates that the token decryption failed. Check whether the token is complete, whether it has expired, whether the region where the token is obtained and the region where the service is invoked are different, and whether the account is restricted due to arrears. For details, see Token Authentication.
