Statistics API

Rationale

We have created a separate service for statistics about your Kindly chatbots. This service is named Sage and lives at sage.kindly.ai. The statistics you can view in the Kindly platform are provided by Sage. The same API that the platform uses is available for you to collect statistics for your own purposes.

Sage has it's own database which contains only non-personal data. When end users chat with chatbots their messages are stored and processed in Kindly's database, and these can be manually or automatically deleted after some time to protect the end user's privacy. The data in Sage's database will not be deleted, but this data doesn't contain the user's message or any personal metadata, only an indication that someone messaged the bot at some specific time. This way we can keep aggregated statistics such as the number of chats per day, while also allowing the end user to have their privacy protected.

Authentication

To access Sage's API, you need to obtain a JWT from Kindly. This token is signed by Kindly and Sage checks the signature to decide whether to allow or deny your API request. Use this token as your authorization header in your API requests. The tokens have short lifetimes, so you can only use the token for a short while before you need to obtain another one.

Obtaining a JWT programmatically

If you have the required permissions, you can create a permanent API key in the platform. This long-lived key can be used by a programmatic service you create to obtain short-lived JWTs which can then be used for statistics requests.

Send API key to api.kindly.ai to receive JWT:

curl --request GET \
  --url 'https://api.kindly.ai/api/v2/bot/<BOT_ID>/sage/auth' \
  --header 'authorization: Bearer <API_KEY>'

Send a request to sage.kindly.ai to test your new token

curl --request GET \
  --url 'https://sage.kindly.ai/api/v1/stats/bot/<BOT_ID>/sessions/messages?from=2019-01-01&to=2019-02-01' \
  --header 'authorization: Bearer <JWT>'

About timezones

All time values in the database are stored as UTC. If you want results in your local timezone, which takes into consideration daylight saving time and other irregularities, you can provide a tz argument to your API request with the tzdb name of the timezone you want:

GET https://sage.kindly.ai/api/...&tz=Europe/Oslo

⚠ Timezone gotchas

The timezone parameter is important to consider if you are making a request where the data is aggregated by day. If someone messages the bot at 9 p.m. (summer time) on Monday in California, this is stored in the database as occurring at 4 a.m. on Tuesday. To get the API results scoped for California time, you would send a request with tz=America/Los_Angeles.

About granularity

Some aggregations can use a granularity parameter, for example the aggregation that counts the number of messages per hour, day or week. You can specify this with granularity=hour, etc. These default to granularity=day if not otherwise specified. Note that hour granularity is only allowed if the time between from and to is one week or less.

About sources and languages

The events that are aggregated by Sage are labeled by which source and language the user and bot were chatting with. Your API requests can be filtered by these values. Not adding any filters to your request will include all data in the results, unfiltered.

Sources

Sources are the different locations where your bot may be deployed. For example:

  • test is source value for conversations by bot builders within the Kindly platform.

  • web is the source value for Kindly Chat deployed on web sites, excluding the Kindly platform.

  • app is the source value for chats via the application API.

If you do not filter by sources, all data will be included in the results, including test data. To select only specific sources, you can send one or more filters like this:

GET https://sage.kindly.ai/api/...&sources[]=web&sources[]=app

You can also select sources to exclude, by prefixing with a minus sign. This means that the API will return data from every source except the ones listed. GET https://sage.kindly.ai/api/...&sources[]=-test

Language codes

The language used to chat between the user and the bot is represented by a two-letter language code. If your bot does not use multiple languages, you can safely ignore this parameter.

If you have multiple languages in your bot and you want to filter by language, you can send one or more filters like this:

GET https://sage.kindly.ai/api/...&language_code[]=en&language_code[]=nb

Statistics APIs

Filtering options

Most of the APIs can be filtered by time, language and source. To see what your options are for these filters, you can send a request to the /meta/options API.

Code example in python

This example requires Python 3.6 or higher (uses f-strings) and the package requests.

You will need to provide two values yourself, the relevant bot ID and an API key with "read statistics" permissions that you have created at https://app.kindly.ai/bot/BOT_ID/connect/api-keys. The code exchanges the API key for a JWT, uses the JWT to get data about the number of messages per day for the bot's lifetime, then renders the data as a Unicode box-character bar chart.

from time import sleep
from urllib.parse import urljoin

import requests

BOT_ID: int = REPLACE ME
KINDLY_STATISTICS_API_KEY: str = REPLACE ME  # get this from https://app.kindly.ai/bot/BOT_ID/connect/api-keys
