Using boto3 to access the rest API I can retrieve my QualificationTypeId,just like I can retrieve my HIT_Type_Id when I create a HIT. With the HIT I can then construct a URL like:
https://workersandbox.mturk.com/mturk/preview?groupId=35E1491KDIVXSN2TCLNVR3G3U5I78V
where that random string is
hit_type_id = response['HIT']['HITTypeId']
How do I construct a URL for the qualification given the string extracted as:
qualification_type_id = response['QualificationType']['QualificationTypeId']
You do it like this:
https://www.mturk.com/mturk/requestqualification?qualificationId=[qualification type ID]
So it'll look like this:
https://www.mturk.com/mturk/requestqualification?qualificationId=32O4TCGYF66STTNO0IKIA3U7WHZ1D4
Be aware that www.mturk.com is the current Worker site, but that they're working on a new Worker site at worker.mturk.com. That new site doesn't yet have support for Qualifications (Workers can request them at www.mturk.com). But it does mean that there's a chance this URL changes at some point in the future.
Hope that helps!
