# Token Service

The Identity and Access Management (IAM) system within the AA ecosystem is responsible for ensuring secure and authorized access to ecosystem APIs. It manages participant roles, such as AA, FIP, or FIU, which are assigned during registration and embedded in the identity tokens issued by Sahamati. These roles govern access to services and ensure that participants can only access information they are authorized for.

To facilitate secure interactions, IAM utilizes Access Tokens—short-lived JSON Web Tokens (JWT)—to authorise participants when they access ecosystem APIs. The Access Tokens, linked to the participant's role, ensure that only authorised individuals or entities can retrieve specific data or interact with services. Through role-based access control and token-based authentication, IAM safeguards the ecosystem's integrity and protects sensitive data while enabling secure communication among participants.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developer.sahamati.org.in/token-service.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
