What types of SMS can I send with the Prelude API?
With Prelude’s SMS API, you can send transactional messages, OTP verifications, notifications, and marketing campaigns directly from your applications.
Messages are routed through direct operator connections, ensuring secure, fast, and reliable delivery.
Typical examples include:
Order confirmations and delivery notifications.
2FA codes and password resets.
Appointment reminders and service alerts.
Personalized marketing campaigns and promotional offers.
Prelude’s business-grade API enables instant, high-quality communication with your customers at scale.
Is the Prelude SMS API compatible with my system?
Yes. Prelude is fully compatible with all major systems — CRM, ERP, SaaS, and e-commerce platforms.
Based on REST/JSON, the API integrates easily with a simple HTTPS request and is designed to work seamlessly with most programming environments.
Prelude also provides:
SDKs and code libraries for Java, Python, Ruby, and Node.js.
Dashboard test numbers and free credits for real message testing.
Real people, fast response available via Slack
This makes Prelude’s API both developer-friendly and accessible to any business.
How can I track the delivery status of my SMS?
Every message sent via Prelude includes a real-time delivery receipt (DLR).
You can monitor and analyze all message statuses directly from your Prelude dashboard or via API webhooks.
Available tracking data includes:
Delivery status (sent, delivered, failed).
Timestamp and message ID.
Routing information and response time.
You can also export these logs to measure your delivery performance and campaign efficiency over time.
Is the Prelude SMS API secure and GDPR compliant?
Yes. Prelude is a European-hosted platform fully compliant with GDPR and SOC 2 Type II certification.
Security is a core priority of our infrastructure:
HTTPS/TLS encrypted connections for all communications.
Token-based API authentication and key rotation.
Data hosting within European data centers.
Prelude guarantees that all user data remains secure, private, and processed in Europe, ensuring full compliance with EU privacy laws.
How is the SMS API pricing structured?
Pay-As-You-Go (default)
Best for: teams who want to launch quickly, stay flexible, and pay only for real usage.
How it works:
Each SMS is charged at the public carrier price.
This price doesn’t change with volume and Prelude doesn’t take margin on it.
Prelude charges a service license fee per message sent.
This is the API/service fee for using the platform.
You get a real-time billing dashboard to track usage and export invoices anytime.
No subscription, no commitment, no platform fee — just usage.
In short: you pay the public SMS cost plus a Prelude service license fee per SMS, with zero lock-in.
License Plan (post-paid + discounted)
Best for: companies with consistent or high volumes that want lower unit costs and monthly invoicing.
How it works:
You move from pre-paid credits to post-paid billing with monthly invoices.
You unlock:
Discounted per-SMS API fees (lower unit pricing),
Custom volume tiers aligned with your expected usage,
Optional upgrades like tailored routing, SLA, or dedicated support (when relevant).
You keep the same transparent dashboard, just with better economics at scale.
In short: the same usage-based logic, but cheaper per SMS and billed monthly once you scale.
How fast are SMS deliveries through Prelude’s API?
Prelude’s infrastructure is optimized for real-time messaging, with average delivery times under three seconds per SMS.
Thanks to direct operator routing and redundant servers, Prelude clients average >98% deliverability, even during high-traffic periods.
This makes it ideal for critical messages like OTPs, alerts, or system notifications that demand instant delivery.
What makes Prelude different from other SMS API providers?
Prelude stands out as a European-hosted, GDPR-compliant SMS gateway built for reliability and transparency.
Key differentiators:
Infrastructure located in France and the EU.
Built-in anti-fraud protection with a 4-layer AI-powered system that filters abuse and ensures only legitimate users can receive OTPs and log in.
Transparent, usage-based pricing with no hidden costs.
Simple REST API and clear SDKs for fast deployment.
Real people support, fast response available via Slack.
Prelude combines enterprise-grade technology with a human-centric approach, ensuring both performance and peace of mind.
