The only difference is delivery. When your routing selects WhatsApp, POST /otp/send returns an actionurl (a wa.me link) and the OTP stays pending. The user opens it and sends the prefilled message, we reply over WhatsApp with their code, and they enter it to verify, exactly as on SMS, email, or Telegram.Thu, 06 Aug 2026 00:00:00 GMTImprovedhttps://otp.com/changelog#2026-07-22-changelog-launchedhttps://otp.com/changelog#2026-07-22-changelog-launchedThis page now tracks notable updates to otp.com: new channels, API endpoints, SDK releases, and improvements to the docs and site.Wed, 22 Jul 2026 00:00:00 GMTNewhttps://otp.com/changelog#2026-07-10-mcp-serverhttps://otp.com/changelog#2026-07-10-mcp-serverPoint any MCP client (Claude Desktop, Claude Code, Cursor, or your own agent) at @otp.com/mcp and it can send, verify, resend, and check one-time codes through your API key.
