Reasons why Rally Lookback Api isn't working?

Could someone help me figure out why I can't access the Rally Lookback Api? I can access the webservice just fine.

For example, when I type this into the browser:

https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/12345/artifact/3563764.js

(using my server name, the correct workspace and a valid ObjectID), I get the HTTP 404 not found error. Is there a specific reason for this? I've tried several different types of queries, and nothing works.

Thanks!

Solution

Lookback API works a bit different from WSAPI - there aren't artifact-ObjectID specific endpoints such as the above. Instead, you would want to do a find query:

GET:

https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/12345678910/artifact/snapshot/query.js?find={"ObjectID":12345678920}&fields=["_ValidFrom","_ValidTo","ObjectID","State"]&start=0&pagesize=1

Alternatively, using a POST:

POST against:

URI: https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/12345678910/artifact/snapshot/query.js

POST data:

{
    "find": { "ObjectID": 12345678920},
    "fields": ["_ValidFrom", "_ValidTo", "ObjectID", "State"],
    "start": 0,
    "pagesize": 1
}

There are some good examples of this, along with a query "scratchpad" that you can use to test queries in your browser, in the LookbackAPI docs here:

A Rally login is required to use query samples.
