E-Way Bill API Integration

Updated on April 1st, 2019 in E-Way Bill

This article explains the purpose and the operational procedure on how to use E-Way Bill API interface to generate, update, cancel or reject e-way bills and also covers the benefits and the different use cases.

Before we start, it is important to know what exactly APIs are and how do APIs work?

API as we call them stands for Application Programming Interface. An API is an intermediary interface that allows two separate applications to communicate with each other. In other words, an API is basically the messenger that delivers your request to the provider and sends back the response to you.

Often developers don’t write codes from the scratch, instead they use APIs to build a functional application. Therefore, a good API makes it a lot easier for a developer to write a program.

What is an E-Way Bill API Interface?

E-Way Bill API is an interface which enables a taxpayer or the transporter to automate their E-Way Bill processes. Using E-Way Bill APIs, a software can directly interact with the NIC server with commands such as generate e-way bills, take bulk actions, update part b, cancel or reject. The API interface acts as an intermediary between the taxpayer system and the NIC system by sending and receiving data.

E-Way Bill APIs are available in simple REST and SOAP format which accepts JSON & XML payload respectively to communicate between both the systems.

Sources to Avail E-Way Bill APIs

When thinking of automating the e-way bill process, it is important to select the right service provider. Since the choice will decide whether the project will be a success or a failure. Provider can be shortlisted on a range of criterion, such as breath of APIs available, support in preferred programming language, security features and examples of the successful integrations by the service provider. Cost can be one of the criterion but should not be the focus if provider fails other important criteria. 

  • NIC E-Way Bill API – These APIs are developed by National Informatics Centre, an organization under Government of India. To avail these E-Way Bill APIs, the taxpayer has to meet certain conditions like:
    • The taxpayer or transporter should have automated invoice generation system.
    • A taxpayer or a transporter should generate at least 1000 e-way bills per day on the e-way bill system.
    • A taxpayer should have SSL or TSL enabled domain name for interface.
    • The taxpayer or transporter should have static IP address.
    • The taxpayer’s automated system should be modified to exchange the data with e-way bill system.
    • The taxpayer or the transporter system should do thorough testing on pre-production site with at least 200 activities.It is important to note that these are just the plain vanilla E-Way Bill APIs made available by NIC. These APIs are difficult to integrate and might not be suitable for most of the companies.
  • Masters India E-Way Bill API – NIC has given access of their APIs to GST Suvidha Providers which are appointed by GSTN, and Masters India is one of them. Masters India E-Way Bill APIs are easily available to taxpayers and transporters without any pre-requisite. Masters India also provides proper documentation and extended support for quick integration.
