Clickatell SMS API
Silicon Valley, California, United States
What it is
Clickatell SMS API provides tools for sending and receiving business text messages, including customer support, promotions, communications and two-factor authentication notifications. Developers can use a basic HTTP API or the REST-based One API. Businesses can set up two-way messaging with short codes or long numbers, and use 10DLC numbers for application-to-person messaging in the United States. A cloud web interface includes reporting dashboards, role-based access and a sandbox for testing. Clickatell says its infrastructure reaches more than 220 territories and 1,000 mobile networks, and its sending service chooses routes based on quality. One API supports SMS and WhatsApp without separate channel programming. The product page describes default end-to-end encryption for business-customer conversations. Users can register a free account; its Prepaid option charges for outgoing messages on a pay-as-you-go basis. Rates depend on destination and message type, and pricing is available on request. Connect includes standard support and a 99.98% uptime SLA.
