How to Choose an SMS API for Your Web or Mobile Application

If you have a website, mobile app, or any other kind of online presence, then you know how important it is to be able to reach your customers via text message. SMS is a quick and easy way to communicate with your users, and an SMS API can make it even easier.

With so much competition out there, it's more important than ever to make sure that you're able to reach your customers quickly and easily. Doing so could mean the difference between a sale and a lost customer.

An SMS API (Application Programming Interface) is a great way for you to send text messages directly from your own website or app with just a few lines of code.

Is SMS Still Important?

You might be wondering if SMS is still relevant in 2022. After all, there are plenty of other messaging channels out there, like WhatsApp, Facebook Messenger, and even email.

The answer is a definite yes! SMS remains one of the most popular messaging channels, with over 6.65 billion users worldwide.

What's more, SMS has a 98% open rate, which is significantly higher than any other channel. This means that when you send an SMS, you can be almost certain that your customer will see it.

What Can an SMS API Do?


SMS is still an integral part of most marketing and customer support strategies, and an SMS API can take your SMS game to the next level by allowing you to:
  • Notify your customers of important information like updates on their orders, changes to your service, or a new sale
  • Send one-time passcodes for two-factor authentication
  • Verify user phone numbers
  • Send appointment reminders or other time-sensitive information
All can be done automatically with an SMS API creating a seamless experience for your customers. So what factors should you consider when choosing the right SMS API for your business? Here are some of the important features that you’ll want to bear in mind:

High Deliverability

The first and most important thing you should look for in an SMS API is a high deliverability rate. This means that when you send a message using the API, you can be confident that it will reach your customer's phone.

The best SMS APIs will have an SLA (Service Level Agreement) in place that guarantees a certain level of uptime and reliability. This is important because it means that you can rely on the SMS API to keep your customer communication running smoothly, even if there are occasional hiccups.


Another important factor to consider when choosing an SMS API is whether or not it will be able to scale with your business. As your business grows, you'll need a bulk SMS API that can handle increased traffic without any issues.

High Security

Security needs to be a major priority when choosing the right SMS API for your business. Make sure that the SMS API you choose has a high level of security, to protect both your business and your customers' data.


The SMS API you choose should also be cost-efficient and have predictable pricing. This means that you'll know exactly how much you'll be paying for each SMS you send, and you won't have to worry about any hidden costs.

Compliance With Regulations

Make sure to check that the SMS API you're considering is compliant with all relevant regulations in the regions in which you are operating before making a decision and always keep up to date with any changes that may occur. The main regulatory bodies to be aware of are those of the national telecommunications regulators, such as the TDRA in the UAE and CITC in Saudi Arabia.

Speak to a reputable vendor's expert team to learn more about compliance in your specific industry.

Detailed Documentation & SDKs

The SMS API you choose should also have detailed documentation and SDKs (Software Development Kits) available. This will make it much easier for you to integrate the SMS API into your existing systems and will make it simpler for you to get started with using the API.

For instance, you may need a specific SDK for your content management system CMS (Content Management System) or eCommerce platform. SDKs can offer a variety of improvements to enhance your SMS API experience such as pre-built integrations for popular platforms and easy to use code samples that you can adapt to your own needs.

Easy Administration and Management

An API should also have an easy-to-use administration interface. Monitoring your SMS campaigns and managing your account should be a simple and straightforward process.

Vendor Reputation and Experience

In any business, it's always a good idea to go with a vendor that has a good reputation and is experienced in the industry. This is especially true when it comes to choosing an SMS API.

Make sure to do your research and read reviews before making a decision. Check vendor references, client case studies, and independent reviews to get a better idea of what others have experienced with the vendor and whether or not their API is optimized for your locality and/or region.

A good SMS API provider will have a good reputation and will be able to provide you with the support you need to get started with using their API.

They should also have a good customer support team in place in case you run into any issues - no matter what channel you use to contact them (email, phone, chat, etc.).

Campaign Module

The vendor's campaign module should also be able to provide you with all the features and functionality you need to create and manage your SMS campaigns. You should also consider using services that offer campaign management as a part of their package.

This will make it much easier for you to keep track of your campaigns and ensure that they are running smoothly.

A good campaign module should enable you to:

  • Create and manage multiple campaigns
  • Send SMS messages to a large number of contacts
  • Segment your contacts into different groups
  • Track the results of your campaigns
  • Schedule your SMS messages in advance
  • Automate your SMS campaigns
