Edit an in-progress AWS Mechanical Turk Campaign

Question

I have started a mechanical Turk campaign where I have forgotten to include instructions to users what to do if a requested item cannot be found. I'd like to modify the HTML of all the HITs to say, "If X is not found, please put 'NOT FOUND'".

However, I cannot find any options for how to edit a campaign that has been published---if I were to stop the campaign, could I edit it then? I'd be annoyed to do that because it would seem I would then have to rekey, and re-merge the tasks completed in batch 1 and batch 2.

Is there a best way to do this?

Answer 1

This is not possible, unfortunately.

The closest thing is the ChangeHITTypeOfHIT operation, but that only allows you to change properties of the HITType that display to worker (Title, description, QualificationRequirements, Duration, etc.) not the Question (e.g., HTML) content of a HIT.

You'll have to cancel the batch and then start a new one with the corrected text.
