All you need to know about GST API access

Updated on:  

08 min read

GST API is an application programming interface under GST. An API acts as an intermediary between two applications so that they can interact with each other. API is an essential aspect of easing GST compliance. This article covers the below topics on GST API.

Ways to access the GST portal

GST is a progressive tax reform implemented in India. It has changed how you interact with your vendors and customers and place control over all the activities. There are two ways to access the GST portal:

  1. G2B: It means the government to business interaction. All businesses can directly access the GST portal for performing various GST compliance-related work.
  2. Using third party applications: A taxpayer can choose to carry out these GST related compliances through third-party applications. These third-party applications can connect with the GST system via secure GST system APIs. These applications may also be developed by third parties known as GST Suvidha Providers (GSPs). These applications can pull the required data from the GST portal and provide beneficial results using GST APIs.

Introduction to GST system APIs

Using a GST API, a taxpayer can connect with the GSTN’s server and perform different functionalities such as filing returns, viewing ledger, pulling payment information, etc. Restful API is used by the Goods and Services Tax Network in India.

Avail third-party services- A taxpayer can use the services of ASP-GSP for GST return filing and other compliance-related work. For availing these services, a taxpayer needs to give access to his GST portal’s APIs. This is a security feature and helps to avoid any unauthorised access to the taxpayers’ information. It allows the taxpayers to control API access on the GST portal. A taxpayer can also disable or limit this access.

Benefits of using APIs

  1. GST API provides integration with the ERP or accounting system of taxpayers.
  2. They have a smart system and deliver 80% results even if the GST servers are down.
  3. Signing up, generating API keys and running requests takes less time. APIs provide faster response time.
  4. GST API can help to view/save different GST returns, check GST returns’ status, and make payments.

Duration for keeping GST API Access active

A taxpayer can keep the API session active for a minimum of six hours and a maximum of up to 30 days. A taxpayer is not required to enter the OTP during this time frame. A taxpayer can choose a longer session if he wants to allow the GSP/ASP to maintain an active session with the GST portal without entering OTP. A taxpayer can also terminate the session for a longer API session and enable the API access and choose a shorter duration.

Issues while accessing GST API

Unable to access the portal- The API access on GST Portal is a permission-controlled feature. A taxpayer needs to activate the GST Portal’s API session, as illustrated in the above topic. He is also required to define the period for which his/her session should remain active. After the period lapses, the GSP cannot access the GST portal. Again permission is required to be given.

Technical challenges- An error message may be received, stating, ‘Your connection is terminated. Kindly reconnect to proceed’. This error message is received due to a technical glitch in the API from the GSTN. For this type of error, one needs to enter the OTP again and then continue with GST filing.
