# Updating Rates

When using multi-currency, this endpoint is used to update the exchange rates for your account. When new rates are sent via this endpoint, the changes will reflect instantly on your store as the product prices are multiplied with the provided rates in real-time.

**Note:** This endpoint should only be used when using multi-currency. Please refer to our multi-currency guide prior to using this endpoint. Incorrect usage of these endpoints will result in a total outage of your personalization setup.

### Token

This endpoint requires a Rates token.

Once the token has been granted, you will be able to find it listed in the [authentication tokens section in the admin.](https://help.nosto.com/settings-and-troubleshooting-faq/settings-authentication-tokens)

## How often should I send exchange-rates?

You can send exchange rates as often as you like but at the bare minimum, the exchange rates should be sent when they are changed.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.nosto.com/techdocs/apis/rest/other/updating-rates-using-the-rates-api.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.
