Communication APIs

Communication APIs are likely to stay for the long haul as companies realize the benefits they offer. Offering businesses more control over their services, they reduce development time and allow companies to quickly and easily integrate with third-party services. As the demand for communication services grows, it’s only a matter of time before business processes are completely streamlined.

What Are Communication APIs?

Communication APIs are application programming interfaces that enable applications and services to interact with one another. They allow users to take advantage of various CPaaS solutions, such as voice calling, messaging, and conferencing, without having to create their own.

They provide a way to bridge the gap between different services, helping developers easily incorporate communication solutions into their applications. With an API, developers can access a wide range of features like audio and video streaming and business text messaging.

On top of that, the APIs permit users to easily integrate their applications with different services, such as Google Hangouts, Slack, and Skype. They provide the means for applications to communicate with one another without the need for manual integration. This makes it easier for developers to quickly add communication features to their applications and services.

These CPaaS APIs are designed to be secure, ensuring that all data remains private and secure. By automatically expanding APIs, the CPaaS functionality expands your business intelligence.

Text Message API Service Pricing

Dexatel employs a pay-as-you-go approach that charges you per sent message. This is the most affordable SMS gateway pricing model, and the service costs are free of setup, monthly, or any other fees.

How Do Communication APIs Work?

Thanks to cloud communication APIs, developers can access and integrate services and data within their applications, websites, and software programs. They use them to enable applications to communicate with each other and exchange data, such as user profiles, messages, and other content.

These work by providing a standardized set of rules, protocols, and data formats for communication between applications. This way, developers can easily integrate different services and technologies into their applications.

Common Types of Communications APIs


An SMS API is a programming interface that enables applications to send and receive text messages. This technology provides a communication channel between applications and mobile networks. It allows developers to integrate SMS messaging into their applications and websites. Businesses can use it for a variety of purposes like sending SMS reminders and alerts, as well as personalized mass texting.

SMS APIs are available for both short code and long code numbers. Short code numbers are used for automated, bulk messaging, while long code numbers are used for individual messaging. The API empowers developers to send and receive messages from mobile devices and personal computers. The API provides methods for sending messages, tracking delivery, and receiving messages.

The combination of communication APIs for SMS makes it easy for businesses to send, receive, and manage text messages. With the help of a bulk service provider, businesses can create powerful applications that help them communicate more efficiently.


Two-way SMS API enables businesses to send and receive SMS messages from their customers. This type of API is useful for customer service, marketing, and other communication needs. Basically, most of the things that a text marketing service provider needs can be accomplished with the help of this technology.

When a customer responds to a message sent by a business, the API sends a response back to the business. The advantage of using a two-way SMS API is that it provides an efficient way to collect customer feedback and track customer interactions. It also reduces the need for manual data entry, facilitating the process of answering customer inquiries.

Verify API

Verify API is a communication protocol that allows applications to interact with one another in order to complete tasks or exchange data. Verify API provides a secure, reliable way for applications to interact and exchange data, ensuring that the data is accurate and up-to-date.

This type of API is used for SMS authentication service by using multi-factor verification, validating data, and verifying the identity of a user. You can also use it to ensure that the data being exchanged is accurate and up-to-date. The API can also be used to provide access control, authorizing users to access certain data or services.

Voice API

With voice APIs, applications can process voice commands and convert them into written instructions, automating tasks and creating more efficient customer experiences. Voice APIs use natural language processing and machine learning to interpret and respond to spoken commands.

As the foundation of modern voice-based applications, voice APIs have made the creation of virtual assistants, chatbots, and interactive voice response systems possible. Thanks to this technology, applications can recognize and respond to messaging voice commands and requests. This can range from basic voice commands to speech recognition, text-to-speech conversion, and sentiment analysis.

With voice APIs, businesses can streamline their customer service processes and automate tedious, manual tasks. They can reduce the need for manual customer service and provide a more personalized and interactive customer experience.

Video API

Video APIs provide developers with standard commands for performing specific tasks, such as retrieving video data, uploading video content, and manipulating video files. APIs allow developers to access a service or application's features without having to understand the underlying code.

Essentially, you need video APIs to interact with video hosting services and streaming platforms like YouTube and Vimeo to upload, manage, and monetize videos. You can also use them to control the viewing experience by providing access to video playback controls, video analytics, and video search capabilities.

Developers can take advantage of features like uploading videos, adding captions and subtitles, and creating customer players thanks to this technology. Some video APIs provide access to video content delivery networks, which can help improve video streaming performance and reduce buffering.

SIP Trunking API

A SIP trunking API allows developers to access and manage trunking services from any number of providers, including telecom carriers and cloud-based providers. It also offers a variety of methods for configuring and managing SIP trunks, including creating and managing SIP users, configuring call routing, and more

By using the SIP Trunking API, developers can create applications that are able to easily integrate with their respective services.

WhatsApp Business API

The WhatsApp Business API is designed for businesses to communicate with their customers via the messaging platform. It allows companies to send messages, such as customer service messages, notifications, and promotional offers. Businesses can also manage customer conversations, track customer engagement, and customize messages for different customer segments.

The API can be integrated into existing customer service systems, such as CRMs and customer service portals. It also supports customer authentication, allowing businesses to easily verify customer identity and securely manage customer data.

On top of that, the messaging app also introduced Meta’s WhatsApp Cloud API in 2022. What sets apart the Business API from the Cloud API is the distinct approach taken by Meta. In the case of the Cloud API, Meta provides a comprehensive package encompassing both hosting services and API access. This unique offering enables businesses to seamlessly access API software upgrades along with vital security enhancements. Conversely, the WhatsApp Business Cloud API boasts premium support services and localized hosting capabilities.
