All data shown in the requests or responses is test data.\n\nOur sandbox environment only covers the scenarios listed in the Postman collection and is open access. It does not allow you to test authorisation or any scenarios beyond the ones documented.\n\nFull specification is available at [https://digital.nhs.uk/developer/api-catalogue/validated-relationship-service](https://digital.nhs.uk/developer/api-catalogue/validated-relationship-service)",
