When using the item API, is there a way to get all results as opposed to a paginated result set? Seems like the limit param is maxed at 100 and is not sufficient in our use case.

It's designed for paged search results and the limit is 100. If you need to do some testing then you can write a script to automatically advance through the pages and dump the results out to an object, but you'd still be limited by the upper limit of 5000

That's the path we're pursuing. We're doing an item CSV export from the PLP but need all the results up to 5000. Thanks for confirming.
