Messaging API FAQs
A messaging API (Application Programming Interface) is a means of seamlessly connecting an application with messaging services and channels. With a messaging API, you can add the ability to send and receive messages via SMS, RCS, WhatsApp, Facebook Messenger and other channels to your own app.Â
This enables apps and the businesses behind them to communicate directly with users (their customers) via the channels and on the platforms they prefer. Precisely which channels a messages API can integrate will depend on the API. Vonage Messages API integrates SMS, RCS, WhatsApp, Facebook Messenger, Viber Service Messages and more.
Â
Omnichannel messaging is the capability of a business to offer a seamless messaging service to customers across multiple channels. It means a customer can hold conversations on whichever channel they prefer and that they can switch channels without losing the thread of that conversation.Â
‘Omnichannel’ in general is an important concept in modern business. With so many different communication channels available, customers expect brands to meet them where it’s most convenient for them. Messaging APIs help businesses to integrate a range of text-based channels into their apps to better cater for the omnichannel demands of modern consumers.
Â
Providing a seamless omnichannel messaging experience has notable benefits for both customers and your business. From the customer perspective, things as simple as having to repeat themselves when they have queries can be hugely detrimental to experience. And it’s those types of problems that omnichannel messaging can help solve.Â
From a business perspective, it’s obviously a good idea to provide a better service to customers. Beyond the benefits of customer loyalty and retention which that brings, too, omnichannel messaging has further advantages. For instance, by letting customers get answers to questions or solve issues via preferred messaging channels, it can take pressure off call centre agents and make them more productive. Omnichannel messaging, too, can help with upselling and cross-selling, in app.
Â
An SMS API is an interface or connector which integrates SMS messaging into your application or software. It’s very similar to a messaging API, except that it’s limited to just SMS messaging, whereas a messaging API like Vonage Messages API can help you integrate SMS and other channels like WhatsApp and Facebook Messenger.Â
TL;DR: All SMS APIs are examples of messaging APIs, but not all messaging APIs are (only) SMS APIs.
Â
The cost of messaging APIs will vary depending on the provider. When assessing pricing, look for providers that make things straightforward and easy to understand. For example, Vonage messaging API pricing is pay as you go, with rates per conversation or message.
