I want to add custom fields to my form submission to Recurly, essentially using them as my database. That way, I could avoid creating a user / prodcuct model and just punt to Recurly's service. Is this possible?
Recurly doesn't have support for custom data, however if you collect extra information it might be possible to store it in used fields like username, company name, or the account-level address information. Just be aware that the format/usage of those fields are subject to change.
