This API allows financial organisations to report Lifetime ISA (LISA) information to HM Revenue and Customs (HMRC) and get information about payments made by HMRC.

The API allows the financial organisation to:

  • report a new investor to HMRC
  • create, transfer or make changes to a LISA account
  • get details of a LISA account
  • report or get details of an investor life event
  • request or get details of bonus payments and withdrawal charges
  • get payment and debt information



You can use the sandbox environment to test this API.

It does not currently support stateful behaviour, but you can use the payloads described in Test data sections of each endpoint to test specific scenarios.

You must set up a test user which is an organisation for this API using the Create Test User API.

Why do these endpoints look different?

The endpoints for this API now use the Open API Specification (OAS).

The API has not changed. You do not need to make any updates to your application if you already use this API.
