# Telemetry

### Introduction

Keyless is inevitably used as part of a wider authentication flow, whether it's an account recovery, login or step-up authentication. Integrators use this feature to collect additional insights around user transactions such as the result, errors and type of authentication and then leverage this data in their own systems for analytics, orchestration or fraud decisioning.

{% hint style="success" %}
Telemetry data can be retrieved for specific transactions using the operationID. This ID is generated via:

* The **Mobile SDK** by passing an operationInfo object to the EnrollConfig or AuthConfig following a specific transaction.
* The **WebSDK** by adding the [Operation\_ID to an authentication](https://docs.keyless.io/web-sdk/web-sdk-reference/add-operationid-to-an-authentication).
  {% endhint %}
