In addition to the benefit of simply being able to automate and integrate SMS sending processes, an API SMS service helps free up limitations by giving you a variety of SMS options that you can automate (as seen in the “endpoints” section below).

Messaging options for optimal possibilities

• Use SMS APIs to send messages globally around the world.
• Not only can you send SMS, you can also include media with MMS. This means you can send images, GIFs, and other files along with your texts. The MMS option also allows you to send out longer messages (up to 1550 characters vs. 160 for SMS).
• The ability to view any replies that your recipient sends in also means you can monitor and carry on 2-way conversations with your subscribers.
• With all of these options for a "send SMS API," the door is wide open with possibilities to use texting to bring a boost to your business or organization.

Subscriber options for convenient management

• You can add or remove contacts via the SMS gateway API at any time.
• In addition, you can easily pull up a list of all contacts in your database.
• Or if you want to view information about a single contact, you can retrieve that using the “Get Subscriber” call.
• These options give you a more convenient way to manage your SMS contacts programmatically.

Group options for efficient organization

• Improve your efficiency with “grouping” (segmentation) options for your contacts.
• You can quickly create “groups,” which are organizational segments by which you can categorize your contacts.
• This allows you to send targeted messages according to the organized segments you’ve set up.
• And this can all be done via the text message service API, so it’s efficient and easy for you.

2FA options for convenient security

• Two-factor authentication via SMS helps keep your users’ accounts secure by requiring them to enter a unique code sent in a text message to their phone.
• You can send out these helpful security texts conveniently through an API for SMS messaging.

Access to web platform and mobile app for maximized options

Are there additional goals you want to accomplish beyond sending basic messages and account management?

The "send text message API" also comes with full access to our own web platform for even more robust options.

So you don’t have to feel limited if you want to explore other possibilities.

How does our SMS service API actually work? What features are included that can help you accomplish your goal?

Authentication method

The SMS API at Mobile Text Alerts uses an API key for authentication.

For any paid account, an API key can be generated under the Settings tab. (If you’re in a free trial account, you can contact support to request your API key.)

You can then submit API requests according to our API documentation.

Compatibility with any programming environment

The text message API can handle any GET requests and is compatible with any programming environment, including:

• Ruby
• PHP
• Python
• Java
• C#
• Any others

This flexibility means you don’t have to get any additional tools or software set up.

Variety of endpoints

Some examples of available endpoints include:

• Send Message (including global SMS messaging API support)
• Add Contact
• Update Data Field
• List Delivery Information
• Create Drip Campaign
• Create Group
• Update Group
• Create Shortened Link
• Create Message Template

See the full list of endpoints in the documentation.

Having this variety of options gives you more choices for programming your API SMS messaging to accomplish whatever goal you’re trying to achieve - whether that’s:

• Tighter security
• Better team communication
• Improved customer satisfaction
• More lead engagement
• Or any other purpose you have for sending text messages

What can you do with SMS API? (Examples & use cases)

Here are some examples of ways SMS APIs can help make your life easier...

Texts triggered by actions or events

Using a "send SMS API," you can set up texts to automatically go out whenever a particular action is taken on your site/app.

This could include actions such as:

• making a purchase
• downloading an app
• abandoning a cart
• filling out a form

“

Thanks for your recent purchase! You can view your receipt here: [link]

Or you could set up messages to be sent in response to certain events, such as:

• a customer’s declined payment
• an account renewal
• an account expiration

These kinds of automated follow-up texts can help boost engagement or sales - or both.

“

Uh-oh! Your card was declined for your recent account renewal. Please update here so that your services go continue without any interruptions [link]

Database syncing with CRMs

Another use for an SMS gateway API would be to pass your CRM database contacts into your SMS contact list.

You could set it up so that whenever a contact is added into your CRM or contact management software, they are also automatically added to your text list and sent a text message.

This saves the hassle of the extra steps needed to manually add your contacts to both or to manually send them a text message.

SMS API FAQ

What is "SMS API"?

If you’re a web developer or have developer knowledge, the concept of a text message API needs no explanation.

But in case you’re not, “API” stands for “application programming interface.”

It’s simply a way to program different pieces of software to connect to each other.

An SMS messaging API, then, allows developers to programmatically send out text messages. Since it's programmatic, you can scale your SMS efforts as needed.

The ability to program a text messaging software means that you have the flexibility to set up your own automations, integrations, and tools to send out text messages on your own terms.

Combine the power of automation with the effectiveness of texting and you’ve got a winning combo.

Through an API SMS messaging service, you can have more control over your sending capabilities, thus leading to less hassle.

What is SMS gateway API?​

An SMS gateway API is essentially the means by which you can send text messages programmatically without the need of a middleman. It's the "path" a text message takes to get from your app to the end device of your recipients.

What’s the cost for an SMS message API?

While the listed plans are already reasonably priced (starting at $20/month), API customers may receive discounted pricing.
