In their own words
ClickSend SMS API
ClickSend SMS API provides businesses with browser-based and API tools to send and receive text messages. The API can send and manage SMS, check sending costs, and show message history. Uses include promotional campaigns, transactional messages such as reminders and delivery updates, and one-time-password verification. ClickSend supports two-way conversations and recurring messaging workflows built through no-code integrations or code. Listed integrations include Zapier, Microsoft Power Automate, Make, GoHighLevel, ActiveCampaign, Salesforce, Bubble.io, and IFTTT; SDKs are available for PHP, Node.js, Ruby, Swift, Objective-C, Python, C#, Java, Go, and Perl. ClickSend says customer connections use TLS 1.2 with AES ciphers and sensitive data is encrypted at rest and in transit. It advertises human-staffed chat support 24 hours a day, 365 days a year, and a 99.95% uptime SLA guarantee. A 14-day trial is listed, but there is no free plan. Pay-as-you-go top-ups start at $20; additional carrier fees apply, and messages over 160 characters are charged as multiple parts. New customers need support approval to send SMS containing URLs.
