Update NLP Configurations

To update the NLP thresholds and configurations

To use this API, app needs the Bot Builder API scope of NLP Configurations.
OR the Admin API Scope of NLP Configurations under Test and Train.

POST https://{{host}}/api/public/bot/{{BotID}}/configurations?language={{languageCode}}&groupName={{groupName}}

Query Parameters

Parameter Required/Optional Description
host Required Environment URL, for example, https://bots.kore.ai
BotID Required Bot ID or Stream ID. You can access it from the General Settings page of the bot.
languageCode Required Bot language to which these configurations need to be updated.
groupName Required
for Multiple ML Model
GroupName can be used to update the ML params of a specific group.  To update Bot level Intent Model Configurations groupName should be set to “Bot Level Intent Model”.

Body Parameters

The parameters would depend upon the threshold configuration that needs to be updated. Following is the comprehensive list of parameters for the various threshold configurations.
