Fetching the data table
• Do a HTTP POST request to the table URL
•
http://api.scb.se/OV0104/v1/doris/en/ssd/BE/BE0101/BE0101A/BefolkningNy
• Add the query as the content of the request
Limitations
• Number of cells that can be fetched => 10000
• Number of calls => 10 calls/10 second base on IP
address
