SDK Overview

To help you interact with our APIs, we created a set of SDKs (Software Developer Kits) for the most common programming languages. SDKs will speed up the integration process. These SDKs provide updated models and methods to contact our APIs with minimal configuration, making it possible to start interacting with the Invoicetronic API within minutes. You only need an active API Key and are ready to go.

Not a programmer?

If you are not a programmer, you can still work with the API using scriptable tools such as curl and invoice (our handy in-house send-and-receive-invoices-from-command-line command), GUIs like Postman, etc. Check our Quickstarts for guidance on using these tools with the Invoicetronic API.

Available SDKs

Our SDKs are open source and released under the MIT license, which means you can use and modify them freely. Their complete source code and full documentation are available on GitHub.

Here is the list of our SDKs, each with a link to the corresponding source code repository and documentation.

Are official SDKs required?

The Invoicetronic API is first and foremost a simple yet powerful REST API. Hence, you can write your code to interact with it; you'll find all the needed documentation in the API reference, the OpenAPI Specification and our Quickstart page. However, we strongly suggest using our SDKs.

  • It simplifies the integration task, providing valuable models and methods out of the box;
  • We'll take care of it for you, updating the models and the dependencies when needed;
  • We'll test and fix bugs that will eventually arise on our APIs.

There are some possible reasons why you would prefer to write custom code instead:

  • Your programming language is not yet supported;
  • You're using an unsupported version of a supported programming language (for example, PHP 5);
  • You have some dependency conflicts;
  • You are using a small subset of our APIs and don't want to install the whole SDK;
  • You are already using a different set of libraries (for example, a different HTTP client) and don't want to introduce another dependency;
  • You want to stay as vanilla as possible.

My language is not supported

We plan to provide SDKs for the most popular programming languages, so your favourite one could be the next! In the meantime, you can:

  • Use the API Reference real-time code snippets for guidance, as they are available for many progamming languages and tools, to write your own code (see the image below).
  • Generate your own SDK: We provide an OpenAPI Specification, so you can use it to generate your homemade SDK (that's how we generate our SDKs too).

In the API Reference, real-time code snippets support many languages and tools.
