Exchange Rates API

This page contains the setup guide and reference information for the Exchange Rates API source connector.


The Exchange Rates API integration is a toy integration to demonstrate how Airbyte works with a very simple source.


  • Exchange Rates API account
  • API Access Key

Setup Guide

Step 1: Set up Exchange Rates API

  1. Create an account with Exchange Rates API.
  2. Navigate to the Exchange Rates API Dashboard to find your API Access Key.

If you have a free subscription plan, you will have two limitations to the plan:

  1. Limit of 1,000 API calls per month
  2. You won't be able to specify the base parameter, meaning that you will be only be allowed to use the default base value which is EUR.

Step 2: Set up the Exchange Rates connector in Airbyte

  1. Enter a Name for your source.
  2. Enter your API key as the access_key from the prerequisites.
  3. Enter the Start Date in YYYY-MM-DD format. The data added on and after this date will be replicated.
  4. (Optional) Enter a base currency. For those on the free plan, EUR is the only option available. If none are specified, EUR will be used.
  5. Click Set up source.
