Frequently Asked Questions About the SMS API for Developers
Is the SMS API RESTful and does it use token-based authentication?
Yes. Grupo Tecnophone’s API is a RESTful API that uses Bearer Token authentication in the header of every request. All communication is conducted exclusively over HTTPS to ensure the security of data in transit.
Which programming languages can I use to integrate the SMS API?
The REST API is compatible with any programming language that supports HTTP requests, including Python, PHP, Node.js, Java, Ruby, Go, and C#. We provide code examples in the most widely used languages, as well as a Postman collection so your team can test the endpoints immediately.
How does sending an OTP SMS through the API work?
The basic workflow is simple: your system generates the OTP code, sends a POST request to the /v1/send endpoint with the destination phone number and message, and our infrastructure delivers the SMS within milliseconds. The authentication token is included in the Authorization: Bearer header. Complete documentation is available at api.grupotecnophone.com/docs/es/.
What are Delivery Reports (DLRs) and how do I receive them?
Delivery Reports (DLRs) are confirmations that indicate the exact status of each message sent: delivered, failed, or pending.
You can configure a webhook so our platform automatically notifies you in real time whenever a message status changes or when we receive an update from the mobile operator.
There are two levels of delivery confirmation:
Operator DLR: Confirms that the message has been received by the mobile operator for delivery. This is included as part of the service.
Handset DLR: Confirms that the message was successfully delivered to the recipient’s mobile device. This service incurs an additional cost and depends on operator support.
What is a Webhook and how is it used in SMS integrations?
A webhook is a URL on your system that our platform uses to send automatic HTTP notifications whenever an event occurs—for example, when a message is delivered, when a customer replies to an SMS, or when a short link is clicked. This allows you to automate workflows without the need to continuously poll the API for updates.
Does the API support MO (Mobile Originated) messages?
Yes. MO (Mobile Originated) messages are replies sent by your customers in response to your SMS messages. Our platform captures these messages and displays them in the MO Received Messages module. If configured, they can also be delivered to your system in real time via webhooks, enabling two-way communication workflows such as surveys, appointment confirmations, customer support interactions, and interactive collections processes.
Is there a sandbox environment available for developers?
Yes. You can request access to a sandbox environment to validate your team’s integration before moving to production. This allows you to test the complete workflow, including message submission, DLR reception, and webhook configuration, without generating real SMS traffic.
How many transactions per second (TPS) does the API support?
The platform is designed to process thousands of transactions per second (TPS). Its architecture, built on load-balanced APIs, distributed processing, and high-speed message queues, can absorb massive traffic spikes without message loss or delivery bottlenecks, making it ideal for critical retail campaigns and large-scale authentication workflows.
