This C# code illustrates how ho set parameters, it should be helpful.

In processTextField method description you can find the possible reasons of error 450:

  • Image file has not been specified.
  • Incorrect region of the field has been specified.
  • Incorrect recognition language has been specified.
  • Incorrect regular expression has been specified.

  • Incorrect field marking type has been specified.
  • The number of cells in the field must be positive number.

  • Task description length exceeds 255 characters.
  • Incorrect password for accessing password-protected image file has been specified.
  • Exceeded quota to add images. This error is returned if the number of images you have uploaded exceeds the number of images you can process with the credits available on your account plus some threshold. You can resolve this issue by topping up your account or by removing the tasks which have been submitted but have not been processed.
