App details


There are thousands of licensed tradespeople in NSW. At api.nsw we have developed a powerful set of APIs to provide publicly available licensing information including: whether a tradesperson is licensed to carry out a particular work or if a tradesperson’s licence is current or expired.

Security and authentification

API NSW generates API keys for APIs and enables authentication to your APIs using policies.

Credential pairs consisting of consumer key and secret are provisioned to clients and stored for future validation. These are issued as per agreement with API NSW.

An OAuth call is required to provide the consumer with an authorisation token that would last approximately 12 hours from the time when request was made. User would need to send this authorisation token with every subsequent request in order to get appropriate results from the API.

For more information see OAuth 2.0
