JSON and LabsMobile's SMS API

The JSON format

The JSON format (JavaScript Object Notation) is a programming language typically used to transfer or store data. It is considered to be an excellent alternative to XML thanks to its agility and simplicity, and is a language widely accepted by developers and used in a wide range of applications.

One of the most common uses of the JSON format is the exchange of data between applications, where one acts as a server publishing an API (Application Programming Interface). This API specifies which operations, parameters and results can be used by clients that want to interact with the server. The calls made to the API with JSON are used with are the HTTP protocol and POST methods. You can therefore get a REST API (http/POST) that uses the JSON format to exchange data.

Advantages of using REST API with JSON

There are a lot of advantages of using a REST API with JSON, for example:

  • The simplicity of JSON syntax makes it very efficient in the way that it codes and decodes data, in addition to the high legibility and interpretation of the data.
  • JSON is widely accepted and used by the developer community. All this knowledge makes the use and adoption of REST API using JSON a lot easier.
  • Currently, the REST API with JSON format is compatible with any language and programming environment. Many environments, platforms, frameworks or languages have functions and features specifically designed for use with the JSON format, including making calls to a JSON API.
  • It is very easy to make changes and to add new fields to an API call function using the JSON format, just make sure to test your API before its deployment.

The LabsMobile JSON SMS API

For all the reasons above, LabsMobile recommends the JSON format, specifically the JSON REST SMS API, to clients that want to send SMS messages. To ensure that our services are compatible and adaptable to the needs of any client, other versions of the API are available: http/GET, http/POST XML, WebService, OneAPI. In the majority of cases, however, the JSON SMS API is recommended for its simplicity, functionality, compatibility and easiness to use.
