Messaging API FAQ

Start building your messaging API for free with Gupshup.

Although free messaging APIs are available, they offer limited functionality that doesn't scale well as a company grows. To participate in contextual, meaningful two-way communication with customers on their preferred messaging apps, a paid messaging API like Gupshup is usually a better choice.

With this API, you can send and receive messages to and from customers in 190+ countries through any kind of messaging app. The API is easy to deploy, and complies fully with all data security/privacy regulations. To get started for free, click here.

With Gupshup, you can add SMS messaging capability to your customer service ecosystem - more easily, effectively and reliably than with any free SMS API alternative on the market. Send timely SMS to capture high-quality, qualified leads, and send automatic updates to customers about their orders and deliveries.

You can even leverage SMS messages to promote your products or services, share special/limited-time/cross-sell offers, and send abandoned cart reminders. All in all, if your goal is to provide tailored experiences to your audience, the Gupshup SMS messaging API far surpasses free SMS API options.

With the right messaging API, it's easy for businesses to programmatically send text messages to their leads or customers. To start, sign up for free on Gupshup. Once you create your account, all you need to do is buy a phone number that your business will use to send outbound SMS messages. The single Gupshup messaging API will take care of the rest.

Whether your messaging apps utilise PHP, Java, REST API, or Python, they can be easily integrated into Gupshup's API. The solution also offers multiple programmable SMS messaging features including Two-Factor Authentication (2FA) key, 2FA OTP, 2FA message, enterprise/international enterprise account, and analytics. Users can also send bulk SMS, create SMS groups, check DND status, send link tracking messages, and more.

An SMS API allows businesses to integrate SMS messaging into their existing software platforms. It is simply a code that allows one platform (or multiple platforms) to talk to and share information with another. The API connects the telecom carrier to the Internet without requiring a platform or other middleman software.

Manual SMS systems are slow, cumbersome, and require human inputs which can lead to errors or delays. An API-based system sends SMS programmatically and automatically to streamline the process. This enables the company to send messages quickly and cost-effectively. With an SMS messaging API like Gupshup, the business can even send messages outside business hours.

An SMS API is useful for sending automated, programmatic SMS messages to customers. However, its functionality is limited since it cannot send other types of messages such as WhatsApp, voice, IP, etc.

A messaging API like Gupshup is a unified API messaging service so you can send and receive messages through any kind of messaging app. So, you can send SMS, WhatsApp notifications, voice messages, email, bot messages, etc. You can even do patch calls, mask or look up numbers, build forms, track links, and more.
