increase HIT reward after publishing HIT in mechanical turk

Question

Does anyone know a way to increase HITs reward after publishing them in mechanical turk? I have published around 2000 hits, and it's going kinda slow. I'm thinking of bumping the HIT reward($ paid to turkers). But i'm not sure how to do this.

Per the documentation:

You can use ChangeHITTypeOfHIT to update any of the HITType properties of a HIT. All properties except for Reward can be updated at any time.

In short, it is not possible. You have to close the HITs and reissue.

UPDATE (July 2014):

AWS reports on the MTurk developer forum that you can now change the HITType of a HIT to one that with a different reward amount and that the documentation is incorrect.

According to this page: https://docs.aws.amazon.com/AWSMechTurk/latest/AWSMturkAPI-legacy/ApiReference_ChangeHITTypeOfHITOperation.html, ChangeHITTypeOfHIT API has be unusable since 2019. What kind of API should we use now? – ywat Oct 29 '20 at 21:06

You can do this with one click on TurkPrime.com (free for academic users) without using the API.

There are additional tools like RESTART that enable you to bump your hit up by restarting the hit. This starts a new HIT and excludes all workers who completed the HIT before the "restart" which has effect of looking like a new HIT and only allowing new workers.

But is it possible to see already published HITs on mturk on TurkPrime? – Seid.M Dec 23 '16 at 09:26
@Seid.M I don't think so, but is is a _planned_ item on the feedback page: http://feedback.turkprime.com/forums/288074-general/suggestions/8523565-connect-with-mturk-account-information-on-prior-hi – Jonathan Dec 27 '16 at 21:44

Yes, you can do this. First, create a new HIT type that specifies the new reward, then update the HITs with that new HIT type.

Use the following functions:

create_hit_type [documentation]
update_hit_type_of_hit [documentation]

If you don't know what data to use to create the new HIT type, first retrieve the HIT type of one of the existing HITs (using get_hit), then create the new HIT type based on that, with updated reward.

get_hit [documentation]
