What Is An SMS Gateway API?

An SMS Gateway API (or API service)is a platform used by businesses who wish to integrate mass SMS functionality into existing CRM or e-commerce platforms to gain mobile text messaging capability. An API (Application Programming Interface) from a reliable SMS Gateway API provider gives businesses mass text messaging capacity without needing to re-structure their CRM or e-commerce platform set-ups.

An SMS Gateway API acts like an intermediary platform to allow different platforms (such as CRM and e-commerce platforms and an SMS Gateway platform) to speak to each other with a dedicated sender id. With an SMS API businesses can level up their SMS Marketing and SMS Campaigns with the push of a button, easily reaching any number of customers in a segment securely and reliably (e.g with two-factor authentication).

The best SMS API providers are the ones who offer unique features and go above and beyond. TrueDialog is one such provider whose unique mass SMS API with two-way communication capacity sets them apart from the rest, ensuring enterprise-grade SMS API features at the lowest prices.

In computer technology terms, API formats provide a set of processes and tools that help build application software to make the process seamless – transferring from your email to a text message to the recipient’s mobile phone number.

From your perspective, no software is required to be downloaded or installed. The SMS Gateway provider is totally web-based which means there is no software needed that will crash your computer – all you need is a web browser, internet access, and a mobile number contact list.

Some of the valuable features of SMS Gateway APIs cover:

  • Fast delivery
  • Easy integration
  • Security
  • Business continuity
  • Use of SMTP, HTTP, SMPP, WSDL
  • Automation
  • Scalability

When comparing the top SMS API providers, there are a number of things to consider to ensure the best outcome for your business based on your needs.

Comparing SMS API providers is critical to ensure that your business gets the best value for money and the correct features. The following factors should be looked into while comparing best SMS API providers:

  • Cost – Lowest costs for mass SMS text messaging with API integration
  • Speed and Reliability – If API is capable of delivering SMS reliably, quickly, and at scale.
  • Ease of Integration – How easy registration, connection, and making API calls is.
  • Integration range – If the API can connect to your CRM platform or E-commerce service
