The Data Access Portal provides RESTful web services APIs for programmatic use of the DAP, as well as an OAI-PMH provider for harvesting metadata.

There are four main groups of web service endpoints that can be used:

Endpoints Status Also known as Access Description Documentation Deprecated /ws/v1 Public – read only Use this to search and access DAP collections.

Documentation no longer available

For information see Deprecation of Stable /ws/v2 Public – read only Use this to search and access DAP collections. Deprecated /api/v1 CSIRO staff only:
  • GET
  • POST
Use this to programmatically create DAP collections.  Not all DAP features implemented. Stable / In Development /api/v2 CSIRO staff only All deposit features available in the DAP user interface.

Comparison of Versions

For searching and accessing DAP collections, we strongly recommend the use of /ws/v2 (

For most existing uses of the deprecated /ws/v1 it would be sufficient to substitute the text

Deprecation of

The original DAP web services interface ( is now deprecated.  We advise all users of this web service to migrate their code to use was decommissioned in February 2024.

/ws/v2 supports all the features of and adds more capabilities.

For almost all uses of it is possible to substitute




e.g.:# old web services # /ws/v2 web services

A notable exception is when encoding DOIs (Digital Object Identifiers). encoded slashes – or “/” – as a tilde – or “~’ – character.  /ws/v2 uses unencoded slashes.# e.g. for # old web services encodes the slash as ~ # /ws/v2 web service does not use an encoded slash

Unlike other identifiers that can be used with /ws/v2, DOIs may only be used to retrieve collection metadata.  Use the restful links found in the response to navigate to other endpoints related to the collection, e.g.# e.g. for # Use the following URL to retrieve the collection metadata. # Get the “versions” value from the response to find URLs for all versions. # This uses the Data Collection ID.
