Retrieve submission as a json with date filter

1. What is the issue? Please be detailed.
My goal is to save the data in my custom ODK DB and also be able to retrieve the submissions via an API so that I can also maintain my own DB. What I was doing is setting the submission_url in the xlsform settings but then I realized that it will simply hit the API and will store nothing on the ODK DB. I searched but was not sure whether it is possible or not.
I also checked the ODK Central API. I am able to retrieve the submissions using instanceId, but is it possible that using the created date as a parameter or something I can get the list of all those submissions that match the created data provided by me? If such a thing is possible it will be really helpful for me to get all submissions of that form and store them in my own DB. I hope my question is clear.

2. What steps can we take to reproduce this issue?

3. What have you tried to fix the issue?
Looked through the APIs provided in the ODK Central API.

Hi @abhinav_sinha!

You can filter submissions with submission_date. You'll find some sybtax examples here :
