Connect a Contact to an Organization through Aha! Ideas API

Due to large amounts of organization, I have 20K+ and 500K contact at MAX (I still didn’t role out the service to all my users to test the issues that will come like this one)

I need help to map the contacts automatically to my organizations because I’m sending very important custom field data to each organization to understand my customer better

If I’m not able to map the contact to the organization there is no point in the whole data that I’m sending.

I know that currently, you can map contact with an organization through a CSV file

but I need a more sustainable solution I'm running a SaaS business and I need things to be more automated and scalable with my user base.

how come all these great features to the organizations custom fields but only allow me to manually assign contact to it

at least provide us with a way to auto-assign with our own roles or as a starter provide an API that helps us assign a contact to an organization.
