    Hi,

    I'm calling Translator Web Service from local program. Thinking that there should be no upper bound on HTTP POST body, I fed in a string of length around 12000. Then exception message says: The remote server returned an error: (400) Bad Request.

    Then I did some tests and found the boundary is around 10X00. If more than this level, server would return the error above.

    So is there official explanation of such error and is this really a "defined" value?

    Thanks so much for your help!

    Best Regards,
    Lynn

    Thanks a lot Chris,

    It's nice to have a defined number. So does it mean that such error would not occur if length is less than 10000? (Although I did successfully got translation with length around 10500...)

    Best Regards,
    Lynn

    Hi Lynn,

    correct, this error is not going to happen with requests of 10000 characters or less.

    Hi Chris,

    Does the maximum length of 10000 characters apply to the source text in the original language (e.g. chinese characters) or it considers the encoded (UTF-8) version of the content request?

    Thanks!

    Hi PublicRelay,

    UTF-8 is the only character encoding accepted by the API. The maximum length of the input is 10000 characters (in UTF-8 encoding). The length of the input counts when calculating the balance of your account.

    Hope that helps,
