Business Registries
# Introduction The Business Registries API is built on HTTP. The API is RESTful. It has predictable resource URIs. The API is documented in OpenAPI format. In addition to the standard OpenAPI syntax we use a few vendor extensions . # Overview The following sections describe the resources that make up the Business Registries REST API. ## Current Version By default, all requests to https://api.abr.ato.gov.au receive the `v1` version of the REST API. We encourage you to explicitly request this version via the `Accept` header. Accept: application/vnd.abr-ato.v1+json ## Schema All API access is over HTTPS, and accessed from https://api.abr.ato.gov.au. All data is sent and received as JSON. Blank fields are included. All dates use the ISO 8601 format: YYYY-MM-DD For example: `2017-07-01` (the 1st of July 2017) All timestamps use the ISO 8601 format: YYYY-MM-DDTHH:MM:SSZ For example: `2017-07-01T11:05:06+10:00` ## Timezones Some requests allow for specifying timestamps or generate timestamps with time zone information. We apply the following rules, in order of priority, to determine timezone information for API calls. ### Explicitly provide an ISO 8601 timestamp with timezone information
