Programmable Messaging APIs made easy with Soprano

Soprano’s Messaging APIs will provide all the tools required to send and receive messages from within an application, and will enable programmable functions to tailor the message to the customer.

Low Coding

One of the great advantages of Soprano Connect’s APIs is that the content, as well as the creation and the processing of the message response, is managed through the portal by creating templates. No code is required to create and manage content, making it easy to integrate your IT systems with your team of developers. Low coding will mean that you have to write fewer lines of code and that the API will be focused on sending the message – making the work of your development team more efficient.

Content Control

With Soprano’s API’s you will be able to create templates in the portal, which enables control over the content of your messages as well as the processing of responses. The lines of your code will focus on the template by delivering only the required parameters. This way, your team of developers will be able to concentrate on making the requests to send the message, reducing the probability of errors associated with the content.
You will be able to easily make modifications to the content directly in the templates, reducing time spent that would normally be invested in the revision of the lines of code as they will remain the same.

Basic Bot

You can make use of our inbound solution to execute actions based on decision trees. The portal will enable you to easily generate decision trees, which you can then include in the API request, and efficiently manage the responses of the recipients of the initial message.

Decision trees manage decisions through keywords or regular expressions. They are designed so that you receive the responses sent by your recipients from communication channels such as SMS, WhatsApp, Voice, and RCS directly into your IT systems.


Soprano Connect APIs allow you to maintain and manage consistent conversations across all channels and get the most out of Omnichannel messaging. With the easy integration and management of two-way communication, your customers will be able to switch from one channel to another without losing the communication context, improving their experience.

Automate Processes

Process automation is one of the core benefits of connecting your IT systems to Soprano Connect through its communication APIs. This will reduce operating costs, increase productivity and minimize communication times. Soprano Connect APIs are designed to easily incorporate communication capabilities in situations where human interactions could be an obstacle. An example of this is when operational notifications must be sent almost immediately without the involvement of additional stakeholders.

The Same Context

Soprano Connect APIs allow you to manage all communication strategies from your IT systems. By integrating with Soprano Connect through its APIs, your employees will be able to take advantage of multiple Soprano Connect capabilities from the software environments that they normally would manage without the need to switch context. This means avoiding the need to switch from one software tool to another. Your employees will be more productive by having communication capabilities in the same software that are implemented in the Soprano Connect web platform.

Users & Cost Centers

Regarding consumptions and costs, Soprano Connect APIs allow you to have multiple users and cost centers associated for better management of your communication strategies. This enables our customers to have multiple user accounts with access to Soprano Connect to take advantage of its communication capabilities. This makes it easy to clearly differentiate the consumptions of your departments and other associated dependencies.

Near real-time monitoring

All traffic between your IT systems throughout Soprano’s integrated channels can be monitored in near real-time directly on the portal. All communication transaction records can be tracked by applying filtered searches.

Centralized administration

Manage user account permissions and roles that will be able to use the API features. This allows our customers to determine cost centers associated with those accounts, as well as the capability to activate or deactivate users.

Centralized administration will allow you to have better control of message templates and reduce the probability of typing and writing errors. You will be able to generate periodic and automated reports based on previously established search criteria that can be delivered directly to an email inbox or to an S / FTP / S server.

Protection and Compliance

Soprano Connect has implemented capabilities to ensure the security of information residing on the platform. It has protocols to ensure the security of information on the way to and from your IT systems. Our APIs also have implemented features that restrict the visibility of information transmitted through mobile communication channels.
