Submit form data through API for humanitarian response kobo

Hello,

I’m looking for an API endpoint to be able to submit data to a form. My Kobo instance is on kobo.humanitarianresponse.info. and I haven’t been able to find any way to submit form data. From what I can gather, the v1 API isn’t available for humanitarian response, and the v2 API doesn’t have a way to submit data - is there a way to do this? Thanks!
