Is there a url for export to csv and deleting a form?

What is the problem? Please be detailed.
Hi, I'm new to ODK and trying to create a very simple widget that can show forms uploaded to ODK aggregate.
The requirements include basic add, delete and export operation.

My question is, is there a url for deleting a form and for exporting a form's submission data as csv ?

I've already found the url for form List, upload form and download xform.

What ODK tool and version are you using? And on what device and operating system version?
ODK aggregate v1.6.0 on Windows 10

ODK Aggregate doesn't have an API for CRUD operations.

Perhaps try the new ODK Central server. https://docs.opendatakit.org/central-intro/ has the docs, and we have the API described at https://odkcentral.docs.apiary.io.
