API Specification and Documentation

Telemetry send

The Telemetry API is a critical component of our system, designed to capture and store telemetry data in a PostgreSQL database. Telemetry is essential for monitoring, analysing, and optimizing the performance and behaviour of our applications.

Telemetry Metrics

The Telemetry Metrics API is a powerful API that enables users to fetch counts of specific metrics directly without the need for Superset. This API serves as a lightweight alternative for quick metric retrieval.

API end point	/api/telemetry/v1/metrics
Method	POST
Headers	NA
Request	{"request":{"startTimeStamp":"2023-12-20 00:00:00","endTimeStamp":"2023-12-23 00:00:00"}} Note: Both startTimeStamp and endTimeStamp are optional.
Response	{"id":"api.telemetry.metrics","ver":"1.0","ets":1703855265432,"params":{"resmsgid":"41f3d180-a64b-11ee-8050-83d462d95035","msgid":"41f3d181-a64b-11ee-8050-83d462d95035"},"responseCode":"SUCCESS","result":{"total_devices":"30","total_plays":"40","total_messages_from_activity_service":"20","total_messages_from_teacher_sakhi_service":"16","total_messages_from_parent_sakhi_service":"29","total_ivrs_calls":"50"}}
Example cURL	curl --location '{{host}}/api/telemetry/v1/metrics' \ --data ''

Telemetry dashboard token

The Telemetry Dashboard Token API is a secure method to acquire an access token for the guest user of Superset. This token can be utilized to embed Superset charts in HTML pages without requiring explicit authentication.

API end point	/api/telemetry/v1/dashboard/token
Method	POST
Headers	NA
Request	{"request":{"dashboardIds":["3f0d276e-67cs-402f-8f9e-123cd67ab012","32c44b86-cs58-4c15-b8b5-123cd67ab012"]}} Note: dashboardIds is mandatory.
Response	{"id":"api.telemetry.access.token","ver":"1.0","ets":1705916905344,"params":{"resmsgid":"63193800-b90b-11ee-9b56-bb19a64b5c02","msgid":"63193801-b90b-11ee-9b56-bb19a64b5c02"},"responseCode":"SUCCESS","result":{"token":"{{token}}"}}
Example cURL	curl --location '{{host}}/api/telemetry/v1/dashboard/token' \ --data ''
