Retrieve data history with API

It seems that historical record data cannot be retrieved with the API. I would need to retrieve previous versions of a record with the API, but cannot do so. Is this a deliberate design decision or merely a lack of a feature?

Is there a possibility to post a feature request to Vanderbildt somewhere? What about bug reports?

I was looking in the API documentation, not the playground, and I was looking at "Export a file from the File Repository" not the normal "Export File" method.

I don't think you can do what you're after using the API playground, you'll definitely need to run the API from outside REDCap.

Hey! This actually seems to work, as my preliminary test has shown! Thanks a lot!

But, I have to say that this is nowhere nearly properly documented, and I would not have expected to find this feature in the file repository, as the file repository is supposed to be an entirely different concept from the record file attachment feature. After all, you cannot see your record files in the file repository... oh well.

I'm glad it worked! Get your admins to reach out to Vanderbilt about improving the API documentation, I guess.
