How many times was a HIT returned?

Hi,

We currently have a set of HITs uploaded on Mechanical Turk and we realize that the uptake (the number of workers accepting and submitting our tasks) is very low. It has been 3 days since our HITs were uploaded and I am wondering if the low uptake has to do with the complexity of our HIT.

My question is - is there as way to fetch the number of times a HIT was accepted and returned? The current API and data structure for a HIT does not include a field with this information - https://docs.aws.amazon.com/AWSMechTurk/latest/AWSMturkAPI/ApiReference_HITDataStructureArticle.html

Any pointers greatly appreciated.

Best,
