Frequently Asked Questions

Getting started is straightforward! Begin by registering for a Zapptext portal account. Next, set up a voice application to receive your credentials (key and secret). These credentials enable you to utilize our REST APIs for initiating and receiving calls, creating conference calls, controlling call flow through our callback API, and more. You'll also have the ability to acquire and manage phone numbers.

Simply log into the portal to browse available numbers across numerous countries. Note that some regions require local presence verification and additional business documentation before number allocation. Contact our team for specific requirements or any queries.

Traditional phone calling involves communication via telephone lines, using either mobile devices or landlines. In-app calling operates through software, transmitting audio and/or video data over internet connections between participants. When integrated into your application, users can initiate calls through web browsers or mobile apps from any global location.
