Transactional SMS Service — Questions Answered
Common questions about business SMS APIs, transactional messaging limits, and TRAI regulations in India.
Transactional SMS is a service message triggered by a customer action or business event, such as an OTP, order confirmation, payment update, appointment reminder or account alert. Textspeed provides transactional SMS delivery through API-based messaging infrastructure for time-sensitive business notifications.
Textspeed provides transactional SMS delivery, API connectivity, DLT registration support, approved sender IDs and templates, delivery monitoring and high-throughput messaging. Its platform is designed for alerts and notifications that need reliable delivery and can be connected to business applications.
Connect your application to the SMS API, authenticate the account, register the required DLT entity, sender and templates, map application events to message templates and configure delivery callbacks. Test OTPs or alerts with representative scenarios before enabling production traffic.
Transactional SMS communicates service or customer-action information such as OTPs, order updates and account alerts. Promotional SMS is marketing communication such as offers and campaigns. Businesses should use the correct message category and approved template for the intended purpose.
Transactional SMS pricing depends on message volume, operator routes, sender and template setup, account requirements and provider pricing. Textspeed should provide the current commercial quote for the required traffic volume rather than relying on a generic per-message figure.
E-commerce businesses can send order confirmations and delivery updates; financial services can send payment or account alerts; healthcare providers can send appointment reminders; logistics companies can send shipment updates. Textspeed can trigger these notifications from application events through an SMS API.
Yes. Transactional SMS can integrate with CRM, ERP, websites and applications through APIs and delivery callbacks. This lets a system trigger an SMS when an event occurs and receive status information for reporting or retry logic. Textspeed supports API-based transactional messaging workflows.
Check the API request, sender ID, DLT template, recipient number, operator response and delivery receipt. Confirm that the message content matches the approved template and that the account has sufficient capacity. For persistent delays, compare gateway responses and delivery reports to isolate application, route or operator issues.
