Send Message

    The SMS API enables you to send an SMS using an API and terminate to the Mobile Network Operators via an http POST request using the Base url https://sms.voxbone.com:4443/sms/v1/ and append the destination E164 and place a JSON body with the information to terminate the SMS.

    Authentication

    The authentication against the Voxbone SMS API is done with Digest Auth. This type of authentication should be a straightforward operation in your language of choice, there are plenty of libraries available for many languages. If you cannot find a suitable library, or are simply curious about how it works, here’s a quick summary : It applies a hash function to a password before sending it over the network, which is safer than basic access authentication, which sends plaintext.

    Login/Password

    The login and password that should be used is distinct from the global account password, it can be set on the sms link you configured with the Voxbone portal under Configure URI > VoxSMS (tab) > Link Creation > or the API.
