Analytics API Documentation

Introduction

Base URL

Version: 1.0.3

Authentication

The API uses JWT token for authentication. The API accepts the token in the Authorization header, in the following format: Authorization: eyJhbGciOiJIUzI1NiIsInR5cCI6Ik...0RMHrHDcEfxjoYZgeFONFh7HgQ This header must be included with every request.

Obtaining the Access token

You can get JWT token from the OAuth2 token endpoint by setting the token_type parameter to jwt. This parameter must be set as HTTP POST parameter.

The OAuth2 flows are described here: http://developers.video.ibm.com/channel-api/getting-started.html

The recommended authentication flow is Client credentials.

Time format

Every time field provided by the API is formatted by ISO8601 format (eg. 2018-07-16T19:20:30+01:00). The API also accepts parameters in this format only.

Terminology

• media: Media is a common word for both live broadcasts and videos
• content type: The API has knowledge of two types of content: live broadcast and videos
• content id: A numeric identifier of the media. For Live it means channel id, for video it means video id
• segment: A part of the media watched by the user

Response times

Depending on your query and the underlying data size the response might take a minute.

Uses default content-types: application/json

Raw view export for a given time period

This endpoint lists every view segments in the requested time period. Segments are generated by events from the users, like play, pause, seek.

The date_time_from and date_time_to parameters control how the Analytics API filters the response. By default the API returns all segments which meet at least one of the following criteria:

• the view started before the date range and ended in the defined range
• the view started and finished inside the defined range or not finished yet
• the view started in the defined range and finished after the defined range or not finished yet

You can control this behaviour with two flags: list_unfinished_segments and inclusive_range. Both parameters are set to true by default. When you set the list_unfinished_segments to false, the API will return only the finished segments. However when you set the inclusive_range parameter to false, only those segments will be returned whose started and finished times are in the defined range.
