Portal API

{PAID API}

GST Identification Number is a 15 digit unique number issued to a business registered under GST. This API lets you verify GSTIN via an OTP-based mechanism. First, an OTP is generated and sent to the registered phone number and email address of the principal contact of that GST business. Then, on successfully verifying the OTP, the associated owner of the GSTIN is verified.

Usecase

GSTIN is publicly available information. Therefore, individuals can wrongly claim ownership of GSTIN when trying to do business with others. Hence, one way to verify the ownership of the GSTIN is to check if the person indeed has access to the phone number and the e-mail id associated with the GSTIN (as per GST Portal).

Example

E-Commerce

E-commerce portal onboard thousands of sellers on a daily basis. Hence, these portals use the API to verify the genuineness of the sellers.
