Prerequisites:

• You already have some FLOW

Steps

1. Open the exchange website

   In this guide we'll be using Intercambio.app.
   
   Simply click on "Intercambio.app" to open it.

2. Perform the exchange

   Select the currency you'll be exchanging from on the left, so in this case FLOW, and the one you'll be exchanging for on the right, in this case API3.
   
   Input the amount of FLOW you want to sell for API3, paste the receiving address for your API3 after the trade is done and click "TRADE".
   
   Finally send the amount of FLOW to the address that shows up on the screen by either copy-pasting the address shown on the page into your wallet or scanning the QR code on the right.

3. Sit back and wait

   Make sure to note down the Trade ID shown on the page in case of issues with the trade.
   
   Transactions can take a while to complete (often as long as an hour) so be patient.
   
   If you encounter any issues contact Intercambio.app customer support with your Trade ID.
