# Fetching data during conversations with Flow Builder

In this guide, you’ll learn how to push and pull data from third-party sources using HTTP requests. We’ll implement a conversational flow that will fetch real-time FX rates from an external API.

 

**Requirements**

* [MessageBird account](https://dashboard.messagebird.com/en/sign-up)
* [WhatsApp for Business account](https://www.messagebird.com/whatsapp/) 

 **Connect it all in the MessageBird Dashboard**

1\. Make sure to sign up for a [MessageBird account](https://dashboard.messagebird.com/en/sign-up) and a [WhatsApp for Business account](https://www.messagebird.com/whatsapp/). Done? Awesome! Log in to your [MessageBird Dashboard](https://dashboard.messagebird.com/en/login) and go to [Flow Builder](https://dashboard.messagebird.com/en/flow-builder).

2\. Import the [main flow here](https://drive.google.com/file/d/1WmOAChY_HcEUVO6L1kJ9pZnnKfUERJAF/view?usp=sharing).

3\. Select **WhatsApp** as the first step in the flow. 

4\. **Publish** your flow in the top-right corner of your screen, and you're good to go!

5\. Done! Every time an end-user engages the main flow and replies 1, the **Fetch Variables** step will call the FX API and respond with the most recent global currency exchange rates.
