# Router API Specs

## Integration Steps

Outlined below are the changes that members need to make to their implementation to use the Sahamati Router.

* Using Sahamati Router API endpoint <https://api.sandbox.sahamati.org.in/proxy/v2> as base path for all the requests.
* Add the recipient ID under the new header **x-request-meta** with **recipient-id** in a JSON object which is the identifier of the receiver to whom the API call needs to be forwarded.
  * The value of the **x-request-meta** is Base64 string of the JSON object with recipient-id.
  * This strucutre helps us to easily extend the JSON object by adding the required attributes for future use cases.

{% hint style="success" %}

```
x-request-meta: <Base64 of JSON object 
{"recipient-id":"<unique identifier of the receiver>"}>
```

{% endhint %}

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.sahamati.org.in/no-longer-relevent/technical-specifications/router-api-specs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
