SMS ITALIA is a simple, fast, and reliable solution for sending professional SMS to Italian numbers, with a customized sender ID and certified quality.
SMS is still today the most direct and effective mobile communication channel: it guarantees a very high reading rate and message delivery even in the absence of an internet connection. It is the ideal choice for immediate and secure communications such as alerts, transactional notifications, two-factor authentication, service notices, and real-time updates.
With SMS ITALIA by Openapi, you can send the same message to one or multiple recipients in just a few moments, easily integrating the service into your systems via API.
The service includes advanced features for full control over message delivery:
- dryRun: allows you to simulate SMS sending and preview the content in advance, avoiding errors and non-compliant messages.
- failOnMultipleMessages: prevents the sending of multiple messages. If the text contains special characters that would cause the message to be split into multiple SMS, the sending is blocked and an ALERT notification is returned.
SEND SMS
The POST/IT-messages method creates and queues a new SMS message to be sent specifically in Italy. It applies country-specific rules and pricing.
IMPORTANT: if the message content or the sender contains prohibited words, the message will be blocked, the account will be added to the block list, and the cost of the message will be charged.
