As an IT Manager, I give utmost importance to the uptime and retrieval of API documentation. HELLO is good at both. The infrastructure appears to be created for global scaling. The REST APIs are well-documented. This proved beneficial to establish the initial handshake and to kick off quickly with our dev team. OTP delivery time is very low. It is very critical since we will route through multiple carriers. Review collected by and hosted on G2.com.

While I appreciate the tech thought that’s gone into the tool, I find the native visualisation of the admin dashboard to be somewhat limited. To troubleshoot or review UP traffic data over a longer historic time period, we need to download the raw logs via API and conduct our own analysis through a BI tool. The capability to view live delivery status on specific populated regions of the world should also be enabled through the “Reporting” section that must add sophisticated and flexible filters.
