Application Programming Interfaces (API)

This section contains essential information about the current Weezzo API as well as step-by-step instructions on how to start using it. The Weezzo API is available to all verified personal or corporate account owners. As new API functions are added and their functionality grows, the information gets updated accordingly.

API Overview

The Weezzo API provides programmatic access to Weezzo features and services. Developers can build custom applications, tools and services that correspond to the same services and tools available through the main Weezzo website, Typical applications include transactions search, mass payments, etc.

The API is based on JSON (or JavaScript Object Notation), a lightweight, easy and popular way to exchange data. It is based on a subset of the JavaScript Programming Language. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

Note: You can find previous versions of the Weezzo SOAP API in the Obsolete API section.


The Weezzo JSON API service is protected to ensure that only authorized Weezzo clients can use it. There are several levels of security:

  1. Using API Key IDs and complex signatures instead of API passwords;
  2. Using a nonce for every API call;
  3. Secure Sockets Layer (SSL) data transport;
  4. Access filtering by IP addresses;
  5. Transaction limits for API Keys.

Authorization failure at any of these levels denies access to the Weezzo API Service.
