Automate SMS, Calls & Modems with Teleleo API
Programmatic access to real SIM cards. Send SMS, manage calls, control modems — all through a clean REST API with token authentication.
Everything the Dashboard Does — Now Programmable
SMS Operations
Send, receive, and manage SMS programmatically. Schedule messages, read incoming texts, and build conversational flows — all from your real SIM number.
Call Management
Initiate and manage calls through the API. Automate outbound dialling, handle call events, and integrate telephony into your existing business logic.
Device & Modem Control
Monitor modem status, manage SIM cards, check signal strength, and control multiple devices from a single API. Target specific modems for each operation.
Webhooks & Automation
Receive real-time notifications for incoming SMS, missed calls, and device events. Build reactive workflows that respond to events the moment they happen.
Secure Token Authentication
Generate API tokens in your dashboard. Each request is authenticated with a bearer token — no complex OAuth flows, no session management required.
Three Steps from Code to Real SIM Card
The API mirrors every feature available in the Teleleo dashboard. If you can do it in the UI, you can automate it.
Generate Your API Token
Sign up for Teleleo, connect your modem, and generate an API token from your personal dashboard. One token covers all endpoints.
Make Your First API Call
Send a GET or POST request to any endpoint with your token in the Authorization header. Full documentation with request examples lives in your account.
Build Your Integration
Connect Teleleo to your CRM, monitoring system, or custom application. Automate SMS workflows, call routing, and modem management at any scale your SIM supports.
Built for Teams That Write Code, Not Click Buttons
The API is designed for technical users who need programmatic control over Teleleo features.
Backend Developers
Building notification systems that send SMS from a real number instead of a short code? The API gives you direct access to SIM-based messaging.
DevOps & Technical Teams
Need modem health monitoring, automatic SIM rotation, or alert-triggered SMS? The API lets you script device management into your infrastructure.
System Integrators
Connecting Teleleo to Zapier, n8n, or custom middleware? REST endpoints and webhook callbacks make integration straightforward.
Workflow Automation Engineers
Replace manual SMS campaigns and call lists with automated pipelines. Trigger messages based on CRM events, schedules, or external API calls.
CRM & SaaS Platforms
Embed real-number SMS and call capabilities directly into your product. Give your users the ability to communicate through physical SIM cards.
Monitoring & Alerting Systems
Send critical alerts via SMS through a real carrier — not through an aggregator that gets filtered. Direct SIM delivery for high-priority notifications.
Real SIM Rules Apply — Even Through API
The API does not bypass your mobile operator. Every SMS and call goes through a real SIM card on a real network.
Operator limits apply. SMS volume, call duration, and data throughput are governed by your SIM plan and carrier policies.- Not a bulk gateway. High-volume blasting may result in SIM blocking. The API is for controlled automation, not mass messaging.
- Fair-use policies. API usage is subject to the same platform limits as the dashboard. Subscription tier determines available throughput.
- SIM balance required. Ensure your SIM card has credit and active services. The API reports balance and status via device endpoints.
Frequently Asked Questions
API access is included with an active Teleleo subscription. There is no separate charge for API calls, but your usage is subject to the same platform limits and fair-use policies as the web dashboard.
No. All operations performed via the API use your SIM card and mobile operator's network. Operator limits, spam protection, and fair-use rules still apply. The API does not provide unlimited throughput or guarantee delivery rates.
No. Teleleo API is not a bulk messaging or call gateway. High-volume SMS or call automation may result in SIM card blocking, delivery issues, or operator restrictions. The API is designed for controlled automation and integration, not mass messaging.
Full and up-to-date API documentation is available in your Teleleo personal account. It includes available endpoints, request and response examples, authentication details, and usage notes and limitations.
Yes. If your account has multiple modems, the API allows you to manage devices individually, target specific modems for SMS or calls, and build custom logic across devices.
The API uses token-based authentication. You generate an API token in your Teleleo dashboard and include it in the Authorization header of every request. No complex OAuth flows or session management required.
Verify your authentication credentials, check API limits and response messages, make sure the target modem is online, and confirm that your SIM card has balance and active services. If issues persist, contact Teleleo support with request details, timestamps, and error messages.
