Add Client

Add Client mechanism initiates the consent-based mechanism of the User being added as Quicko's ERI Client. To perform Fetch/E-File ITR, the first step is to add the end-user as Quicko's ERI Client.


  1. API User initiates Add Client by providing taxpayer information
  2. Sandbox initiates and passes the add client request to Income Tax Department
  3. Income Tax Department initiates an OTP on the taxpayer mobile and E-mail
  4. Taxpayer provides OTP to API User and API User performs OTP Validation
  5. Taxpayer is added as Quicko's ERI Client on Successful Validation
