Download dataset

Guide to downloading datasets

As data.gov.sg is a public shared service, we will apply quotas to ensure that they are fairly used by all users. If you exceed the quota of 5 requests per minute, you’ll likely receive a 429 Error. For higher rate limits - create an API key

This API initiates the download of a single dataset, with optional filtering by columns and rows. For datasets that do not have the CSV extension (ie GeoJSON, KML, PDF etc.), you may skip this endpoint and proceed to the Poll Download API below.

To find the dataset_id, refer to the URL of dataset. For this dataset: https://data.gov.sg/collections/522/datasets/d_11e68bba3b3c76733475a72d09759eeb/view or https://data.gov.sg/datasets/d_11e68bba3b3c76733475a72d09759eeb/view

The datasetId is: d_11e68bba3b3c76733475a72d09759eeb

For staging, note that the dataset_id might differ between staging and production:

• Domain: https://api-open-staging.data.gov.sg/

• Example: https://api-open-staging.data.gov.sg/v1/public/api/datasets/d_8b84c4ee58e3cfc0ece0d773c8ca6abc/initiate-download

After initiating the download of a dataset, this endpoint below returns a link to access the dataset

Filters defines how users want to filter their dataset. Filters is an array of objects which have columnName,type and value attributes. columnName refers to the column where the filter is to be applied. The values for type can be EQ, LIKE, or ILIKE. EQ is direct comparison for filter and is case sensitive. LIKE is similar to EQ but includes partial matching. Any words containing the string in the value attribute will be matched. ILIKE is the case-insensitive version of LIKE.

Example: {"fitlers":[{"columnName":"epi_week","type":"EQ","value":2},{"columnName":"status","type":"ILIKE","value":"covid"},{"columnName":"epi_year","type":"LIKE","value":23}]}
