Request parameters

string

Format - guid. The application ID.

string

The task version ID.

Request headers

string
Media type of the body sent to the API.
string
Subscription key which provides access to this API. Found in your Cognitive Services accounts.

Request body

A model object containing the name and regex pattern for the new regular expression entity extractor. Regular expression options applied to the pattern are: ignore case, ignore cultural differences in language.

The name of the regular expression entity must be unique in the application and must not be used by a prebuilt entity.

Example The example syntax will match all of the following:

Text Usage
KB123456 all capitals
Kb123456 first capital, second lower case
kb123456 all lower case

Note about using syntax in Test Console If you are using the Test Console, do NOT use backslash + dot, \.. The Test Console doesn't let this regex syntax pass through correctly.

{
        "name": "kb article",
        "regexPattern": "kb[0-9]{6,}"
}

Response 201

The ID of the created model.

"3d73462d-98f0-4dcd-8d30-fab9e65f2e73"

Response 429

Response 400

This error can be returned if the request's parameters are incorrect meaning the required parameters are missing, malformed, or too large.

This error can be returned if the request's body is incorrect meaning the JSON is missing, malformed, or too large.

This error can be returned if you are attempting to create an entity when the max entity count is exceeded.

{
  "error": {
    "code": "BadArgument",
    "message": "An application cannot have more than 20 regex entities."
  }
}

This error is returned if the regex is invalid:

{
  "error": {
    "code": "BadArgument",
    "message": "Failed to parse regex entity extractor creation object. Parameter name: regexEntityExtractorCreateObj"
  }
}

Response 401

You do not have access.

Reasons can include:

  • used endpoint subscription key, instead of authoring key
  • invalid, malformed, or empty authoring key
  • authoring key doesn't match region
  • you are not the owner or collaborator
  • invalid order of API calls

Response 403
