We would like to create a custom membership application using the API, that allows people to become members and pay via credit card to instantly become members, and therefore gain access to the website.

Looking through the API docs, I'm unsure what the process is for creating a new member, and to retrieve the payment link to allow them to pay as part of the application process. The public non-admin API requires a wild apricot member to be logged in, right? So is processing a new application via the admin API possible?

Any help or guidance would be much appreciated, thanks.
