Tips for scrapping drawing results from Da Ma Cai (a lottery in Malaysia) website. This method works as of 7 July 2024. This is an undocumented method and not officially supported, so it might not work in future.

Get Draw Dates

Draws are conducted every Wednesday, Saturday and Sunday at 7 PM, and some Tuesdays. So it is not always consistent. If you need to get draw results for different days, you need to know what are the draw dates.

Send a GET request to https://www.damacai.com.my/ListPastResult. It returns a JSON object with a single drawdate attribute. The value is a string containing recent draw dates separated by space. The dates are in "YYYYMMDD" format.

This is a bad design. They could have used an array instead of string. Take note of the trailing space in this string. I recommend ISO 8601 date format for APIs.

Example request

curl 'https://www.damacai.com.my/ListPastResult'

URL Link For Draw Results

To get the draw results, you must first retrieve an URL link (for a selected date). This link will direct you to the draw results.

Send a GET request to https://www.damacai.com.my/callpassresult?pastdate=<YYMMDD>. Replace "<YYMMDD>" with a draw date. You must include a HTTP header cookiesession: 363.

Example request

curl -H 'cookiesession: 363' 'https://www.damacai.com.my/callpassresult?pastdate=20240707'

Example result

{"link":"https://prddmcremt1.blob.core.windows.net/drawresult/DrawDate/20240707.json?sv=2014-02-14&sr=b&sig=gErL79ZbcEIDQ%2FlAmq6ZT1fOR%2FQqRWVk%2BslMtR0NXGE%3D&st=2024-07-07T15:10:38Z&se=2024-07-07T16:20:38Z&sp=r"}

It seems to be signed and valid for 1 hour.

Final Step

Send a GET request to the link URL. The response is draw results in JSON format. There is a number of spelling errors. "Past" is sometime spelt as "pass", "consolation" is sometime spelt as "consolidate". The misspelled words and inconsistent naming convention triggers my OCD 🤢.

Example request

curl 'https://prddmcremt1.blob.core.windows.net/drawresult/DrawDate/20240707.json?sv=2014-02-14&sr=b&sig=vRNxKXftDFgWH1fWnQOoaVliFAIE0MffQ6m5B%2FysBVU%3D&st=2024-07-07T15%3A14%3A19Z&se=2024-07-07T16%3A24%3A19Z&sp=r'
