To use the Vcards API you will need an API Token, which can be requested from [email protected]

With that token, you’ll be able to access our API. You should send the token in every request to our API, in order to authenticate and identify yourself. For every request, you should pass the Authorization HTTP Header containing your token, prefixed by “Bearer “ string. Example below:

curl -H 'Authorization: Bearer YOUR_API_TOKEN'

An authentication error message would return a message like the following:

    "error": {
        "status": 401,
        "message": {
            "base": [
                "Not authenticated"

Please note that the error messages that use the same structure of an error node will display a message node. The message displayed will result when the incorrect syntax is used in the desired field. A base error is a general error that cannot be related to any field submitted The fatal node is a system error that will occur when the incorrect format is entered into a field, such as when letters are used in the amount field. This will result in a system error. All messages also contain an HTTP status follow W3C recommendations, e.g. an unauthenticated request will issue an HTTP status 401.

We include the HTTP status on the JSON message, as well as on the headers of all JSON error responses.
