The account API provides either a list of accounts for an identified customer or information about a single customer account. It is 1 of 8 APIs that, together, make up the customer services suite.

How customer services work

An account represents a tax type (for example, income tax) or a product (for example, KiwiSaver). 

How the account API works

When integrated through our gateway services, the account API provides general information about customer accounts. The account API accepts either a customer ID or an account ID. When a customer ID is provided, the account API will return a list of account IDs associated with the customer. When an account ID is provided, the account API returns information about that identified account including:

  • account status
  • account type (tax or product name)
  • filing details
  • start and stop dates
  • physical address
  • postal address
  • primary contact details (contact and phone)
  • secondary contact details (contact and phone)
  • refund bank account.

The account API can only be used by:

  • the customer the account is associated to
  • a user with delegated access to the customer’s account
  • an intermediary who’s linked to the customer’s account
  • government agencies with a memorandum of understanding that allows them access to customer account level data.

Some customers may split their individual account access across delegated users. This means a user may not be able to see all accounts for a specific customer. 

The account API enables the above users to query Inland Revenue’s customer account data from their native systems, and to avoid the use of manually facilitated channels.
