Whoosh Programmable Messaging API is one of 2 APIs that [Totogi](https://apis.io/providers/totogi/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Messaging, SMS, A2P, CPaaS, and Webhook. The published artifact set on APIs.io includes API documentation, an API reference, a getting-started guide, and SDKs.

Whoosh! is Totogi's Application-to-Person (A2P) messaging API, launched in September 2023 and positioned as a drop-in replacement for Twilio's A2P APIs that network operators can resell to keep enterprise messaging traffic and revenue on their own network. The REST surface deliberately mirrors Twilio's 2010-04-01 account/resource shape — POST to /2010-04-01/Accounts/{AccountSid}/Messages.json with To, From, and Body (1600 characters max) — and authenticates with HTTP Basic using an Account SID and Auth Token issued from the Whoosh console. Delivery status is pushed back via a StatusCallback webhook that POSTs on queued, failed, sent, delivered, and undelivered. Quickstart documentation is public and un-gated; the console that issues credentials is not, and there is no self-serve signup.
