The Octopush SMS API service provides an authentication key for your SMS campaigns. This is your personal, secret, and unique code that identifies you every time you connect. It saves you time by eliminating the need to re-enter your personal details, as they are securely stored behind this key. The benefit is that it keeps your personal data safe, prevents unauthorized use of your services, and allows you to monitor your traffic.

No third party can access your data.

For this reason, your authentication key must remain secret and should never be shared with anyone.
This key must be used via the API key service for any request you make, whether you are checking your balance or launching a new campaign.
