How to use the Text4biz SMS API?
You can use the Text4Biz SMS API to query information about inbound and outbound messages, send and receive SMS messages, manage contact lists, schedule recurrent texts, process bulk SMS messages and create templates. Here’s how you can get started with the Text4Biz SMS Gateway API: Step #1: Obtain your SMS API credentials. The login credentials (X-TM-Username) are different from the API credentials (X-TM-Key). Note: Text4Biz has two SMS APIs (V1 and V2). If you already have a V1 key, it will not be compatible with the Text4Biz REST API, so you will have to create a new key for the V2 endpoint. Step #2: Connect to the API endpoint (https://rest.text4biz.com/api/v2). Step #3: Try out the Text4Biz Sandbox before you start writing your code.
What is an SMS API?

An application-programming interface (API) is a set of programming rules, standards and instructions for accessing a web-based application. SMS APIs are generally released to the public to enable developers to power their services with the API.

The end user only sees one interface, but behind the scenes, many APIs are working together and integrating with SMS solutions to provide a seamless experience.

In how many ways can the Text4Biz SMS API be used?

The Text4Biz SMS API provides a means of communication between your service and the SMS gateway, thus allowing you to send and receive text messages, check reports and delivery states directly from your application’s interface. Our SMS API can be used in two ways:

  • The REST API provides access to all our messaging gateway features.
  • The Email to SMS API can be used for two-way SMS communication. It does not require additional coding.
Does Text4Biz provide public SMS API documentation?

Of course! Our team has prepared a comprehensive SMS API documentation that will help you build your own messaging app through our infrastructure. Our documentation includes information on sending, receiving and scheduling text messages, email to SMS capabilities, distribution lists, custom fields, accounts and sub-accounts, statistics, encoding and more.

Where can I find the Text4Biz SMS API Code Libraries?

Our developing team has also created a set of client libraries for the most common programming languages. They will allow you to integrate our SMS API into your source code in a matter of minutes.

SMS API Code Libraries: here (includes Node.js, PHP, Java, Python, Go, Delphi, Ruby, .NET, Perl, C++, Shell and C#)

How can I obtain Text4Biz SMS API credentials?
Before you get started with the Text4biz REST API, you have to generate your API credentials and connect to the API endpoint. This can be done by creating an API key. Log in to your Text4biz account and navigate to the API settings. Click on the ‘Add new API key’ button and write down the API label to generate your API credentials. The API key should now appear as a green notification banner above the table.
