+# 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.

+| API end point  |  `/api/telemetry/v1`     |
+| Method         | `POST`                   |
+| Headers        | `NA`                     |

+| Response       | `{"id":"api.telemetry","ver":"1.0","ets":1703855749239,"params":{},"responseCode":"SUCCESS","result":{}}`    |
+| Example cURL   | `curl --location '{{host}}/api/telemetry/v1' \ ` <br> `--header 'Content-Type: application/json' \ `<br> `--data '{"id":"api.djp.telemetry","ver":"3.0","params":{"msgid":"17afd6b09dd6448c891829d9f4af904a"},"ets":1703229372363,"events":[{"actor":{"id":12,"type":"System"},"context":{"channel":"ejp","did":"b8e7cad5-9fcb-11ee-8b98-acde48001122","env":"IVRS","pdata":{"id":"dev.ejp.ivrs","pid":"ivrs-service","ver":"1.0"},"sid":12},"mid":"START:b8e7cad5-9fcb-11ee-8b98-acde48001122","ver":"3.0","eid":"START","edata":{"mode":"start","type":"session"},"ets":1703229372363}]}'`                     |
+
+### 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"}}` <br> **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"]}}` <br> **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 ''`                     |
