Authkey.io

Authkey.io is a versatile and comprehensive one API platform for SMS, voice, and email communications that keeps businesses connected with clients or end-users. The software enables companies to send notifications, OTPs, newsletters, order confirmation messages, timely offers, shipment tracking updates and more via multiple communication channels such as SMS, voice and email. Authkey's parallel sending feature permits simultaneous sends from the same source but with different purposes; minimizing the time it takes to reach out to all users by optimizing message distribution using multiple channels.

Moreover, the software's custom fallback not only ensures that critical information about OTPs and other vital data is conveyed even in case of channel failures but also provides event-based sending options enabling customized messages delivery through SMS, e-mail and voice; making certain message synchronicity which guarantees an efficient process flow. Setting up webhook API integration alerts makes it possible to keep track of what’s happening on your account while 2FA APIs ensure secure transmission of passwords across various platforms saving you valuable time allowing you focus on your core business goals.
