Hi @jackson93,

Try changing your query to something like:
.../Submissions?$filter=__system/submissionDate ge 2023-11-13T00:00:00.000 and __system/submissionDate le 2023-11-17T00:00:00.000
__system/submissionDate is a known system property of Submission that can be used in OData filters with the le and ge comparisons you have discovered.
(start and end are probably something you saw in a Central URL but that is separate from the OData API.)
I don't think you need datetime in your query.
