I currently work for the corporate office of a franchise, which has sites on unique domains for each franchise and, in many cases, a separate site for specific people within those franchises, again on their own unique domain. We’re going to be rolling out another product soon which will allow users to quickly and easily create their own site, on their own domains as well. All in all, we already have several thousand domains and are likely to have an ever increasing number of them.
Ideally, we’d like to enable twitter cards for all of them. Manual approval for a few sites is OK, it’s a pain but achievable for 100s or even 1000s of sites, but when we allow purely automated on-demand site creation, then it’s looking more or less impossible.
Is there any other approach than manually coming and requesting approval on a per domain basis, e.g. an API through which we can request approval as new sites are created, some form of IP based approval, or anything else?
