google spreadsheet feeds with multiple worksheets

Question

How to get feeds from multiple sheets using google spreadsheet feeds api? Below URL fetches the feeds from first sheet only. In my spreadsheet I have 3 work sheets and I want to fetch remaining sheets data as well.

https://spreadsheets.google.com/feeds/list/XXXXMYKEYXXXX/od6/public/values?alt=json-in-script

How to fetch them?

I tried below without success:

https://spreadsheets.google.com/feeds/list/XXXXMYKEYXXXX/od7/public/values?alt=json-in-script

Note od7 instead of od6

UPDATE URL for the spreadsheet feed is https://spreadsheets.google.com/feeds/list/1c53H0piyduOV6zRwS54A7MDZ3SooJOmj4O52Xd0dyIA/od6/public/values?alt=json-in-script

In the spreadsheet I have TopicA,TopicB,TopicC sheets. Feeds response contains TopicA information only.

Answer 1

It seems worksheet IDs are numbered from 1 to n and not like od6, od7. Using below urls, I was able to get individual worksheet's data
https://spreadsheets.google.com/feeds/list/1c53H0piyduOV6zRwS54A7MDZ3SooJOmj4O52Xd0dyIA/1/public/values?alt=json fetches first worksheet
https://spreadsheets.google.com/feeds/list/1c53H0piyduOV6zRwS54A7MDZ3SooJOmj4O52Xd0dyIA/2/public/values?alt=json 2nd sheet
https://spreadsheets.google.com/feeds/list/1c53H0piyduOV6zRwS54A7MDZ3SooJOmj4O52Xd0dyIA/3/public/values?alt=json 3rd sheet and so on

Note the /1, /2 and /3 after the key (1c53H0piyduOV6zRwS54A7MDZ3SooJOmj4O52Xd0dyIA) in the url
