CKAN Data API
Access resource data through the CKAN DataStore API. The examples below use this resource's ID.
Endpoints
The Data API provides these actions. Creating or updating records requires appropriate permissions; the query actions read public DataStore records.
| Create | https://ckan.cdt.dev.datopian.com/api/3/action/datastore_create |
|---|---|
| Update / insert | https://ckan.cdt.dev.datopian.com/api/3/action/datastore_upsert |
| Query | https://ckan.cdt.dev.datopian.com/api/3/action/datastore_search |
| Query via SQL | https://ckan.cdt.dev.datopian.com/api/3/action/datastore_search_sql |
Query examples

Use the resource's OData URL and its field names for paging, selecting columns, or filtering rows.
ODATA_RESOURCE_URL?$top=5
ODATA_RESOURCE_URL?$skip=5&$top=5
