# 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 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: "}> ``` {% endhint %} --- # Agent Instructions: 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.
