Getting Started


Welcome to Sandbox API Documentation! India's first complete Tax Compliance API Platform.

Sandbox can help you with integrating Tax compliance in your products and workflow. We have grouped our APIs into four sections, namely:

  1. Income Tax API: With our E-Return Intermediary License (ERI) we enable our partners to get access to numerous functionalities like reading past ITR, filing ITR, etc.
  2. GST API: Our GST APIs assist our partners to verify business and manage their GST compliance requirements using our GST APIs.
  3. TDS API: Our TDS APIs similarly assist with TDS verification and compliance requirements.
  4. KYC API: Our carefully selected KYC APIs allow verification of PAN, Bank Account, Aadhar verification (soon to come!).
