Your application creates the instruction. The connected communication endpoint performs the operation.

FROM SOFTWARE TO THE MOBILE NETWORK

Your application becomes the brain. The connected phone becomes the endpoint.

SMSMobileAPI links business software to real communication resources without forcing the user to abandon the phone, SIM and number already used by the organization.

CHOOSE YOUR INTEGRATION PATH

Start with the method that fits your team.

The same SMSMobileAPI account can serve a custom backend, an SDK-based application and ready-made automation tools. Use the simplest path that still gives the control your product requires.

01
API

Direct REST API

Use standard HTTP requests from virtually any backend language. Best when you need complete control over validation, business logic and user experience.

Open developer hub →
02
SDK

SDKs and CLI

Use Python, PHP/Composer or terminal-oriented tooling to reduce boilerplate in applications, scheduled jobs and internal automation.

03
↔

Ready-made connectors

Choose Zapier, CRM, e-commerce, calendar and business integrations when a maintained connector already matches the workflow.

ONE PLATFORM, FOCUSED API REFERENCES

Integrate only the capabilities your product needs.

Each category has dedicated documentation. This keeps parameters, examples and operational requirements clear instead of hiding everything behind one generic endpoint.

01 · SMS API

Send and receive SMS

Send through connected mobiles, retrieve incoming messages and build two-way workflows.

16 operations → 02 · CALL API

Use mobile call events

Retrieve missed, incoming and outgoing call activity from connected phones.

7 operations → 03 · NOTIFICATION API

Reach connected devices

Send and retrieve mobile notifications for operational workflows.

3 operations → 04 · WHATSAPP API

Send and recover messages

Use the linked WhatsApp environment with the required synchronization controls.

9 operations → 05 · EMAIL API

Add mailbox workflows

Send email, retrieve activity and respect unsubscribe status.

4 operations → 06 · DEVICES

Operate multiple mobiles

Connect several phones and choose the appropriate resource for each supported action.

FIRST CONTROLLED REQUEST

Send an SMS from your backend in one HTTP call.

Keep the API key on the server, validate the recipient and message, then inspect the returned result and dashboard activity before automating live customer traffic.

  1. 1Connect a mobile and verify that it is online.
  2. 2Store the API key in protected server configuration.
  3. 3Send the test to a number you control.
  4. 4Handle the response and operational errors.

Server-side requestHTTPS

FIT THE PLATFORM INTO YOUR STACK

Use SMSMobileAPI as a communication layer, not a separate silo.

Connect business triggers, databases, workflows and customer interfaces to one platform while keeping the delivery resources and activity visible in the dashboard.

EXAMPLE

A CRM creates a follow-up request. SMSMobileAPI routes an SMS through the selected mobile. A received reply is recovered and attached to the correct contact workflow.

Business trigger → API → real mobile → contact

One API layer can connect code, workflows, business applications and communication endpoints.

PRODUCTION CHECKLIST

Design for security and operational visibility from day one.

A successful communication integration is more than a working HTTP request. Protect credentials, validate inputs, manage failure states and make activity observable for the people operating the product.

  • 01
    Protect API credentialsKeep keys in server-side secrets or environment configuration, never public JavaScript.
  • 02
    Validate every requestNormalize recipients, restrict message length and reject incomplete data.
  • 03
    Handle real failuresUse timeouts, bounded retries and explicit handling of API and device errors.
  • 04
    Keep operations visibleStore useful request references and monitor dashboard or API activity.
  • 05
    Test with controlled dataValidate each channel and device before enabling production automation.
  • 06
    Respect channel requirementsFollow the specific connection, synchronization and consent rules for each capability.

INTEGRATION FAQ

Choose the right technical starting point.

Start from the developer hub, select one communication category and build a controlled end-to-end test before expanding the integration.

Do SMS really leave from a connected mobile?

Yes. With the native mobile gateway, SMS requests are routed through the connected phone, its SIM and mobile number. The phone must be online and correctly configured.

Which programming languages can use the REST API?

Any server-side environment capable of making HTTPS requests can integrate the REST endpoints. Python and PHP resources are also available for teams that prefer an SDK-oriented start.

Can one account use several connected phones?

Yes. SMSMobileAPI supports multiple connected devices. Use the documented device-selection capabilities where the chosen endpoint exposes them.

Should an API key be used in browser JavaScript?

No. Keep the API key in protected server-side configuration and let your backend authorize the business action before calling SMSMobileAPI.

Must I build everything with code?

No. Use a ready-made CRM, e-commerce, calendar or Zapier integration when it covers the workflow. Build directly on the API when the user experience or business logic must be custom.

YOUR SOFTWARE. REAL COMMUNICATION ENDPOINTS.

Build the integration your product actually needs.

Choose one capability, connect a controlled account and move from the first API request to a secure, observable production workflow.
