VatZen is Deprecated since January 2022 and API server will be shut down soon!
In order to use the service, you have to attach your personal api key to each request you make. You can find, create and regenerate your personal api key in your dashboard at https://dashboard.vatzen.com.
VatZen API Authorization is based on your personal api key, which you can obtain from the dashboard. You're required to pass this api key along with every request you make to the API. You can pass it in 2 ways: via x-api-key header in HTTP headers, or in the request query as an api_key parameter.
Below, 2 examples of how you can provide your api key.
1) Provide a token in the request's query
Simple example of how to use your token inside the request's query to fetch all the actual API rates:
You can reset your api key anytime from your dashboard if you think that your token has been compromised. In order to to that, you can navigate to the "API Key" section of the dashboard and click regenerate button.
