SMS API

SMS API

Integrate Reliable USA SMS Into Your Stack

The AntiSpamSMS API gives developers clean endpoints to send messages, retrieve status, and automate workflows across OTP, alerts, and campaigns. Authenticate securely, post payloads with clear error codes, and subscribe to webhooks for delivery events.

Our docs emphasize practical examples-Node, Python, and REST patterns your team can paste into staging environments. Idempotency keys, pagination for logs, and sandbox testing help you ship with confidence before production traffic.

Automation Without Guesswork

Trigger SMS from billing events, fraud checks, shipping updates, or user lifecycle milestones. Combine the API with anti-spam content guidance so programmatic sends stay on-brand and carrier-friendly across the USA.
