How do I test against a custom field value?

What I'm trying to do here is to create a 'simple' script that will check a random number against what is in the CM db. The way it works is I'm using a hidden field to insert a random 8 digit number into a custom field (what/why you ask? my boss wants to send a "registration code" in the confirmation email, and then when the customer uses said code to make their purchase, I want to check that it's a valid number), which is then sent to the user in the confirmation email. I've got everything working as far as creating and inserting the number (using a few simple lines of PHP, nothing API related), and I can see that the number is making it into the custom field, as it's getting passed back to me in the confirmation email, and I can see it in the subscriber details page.

Now I just need to figure out how to use the API to check that the number is actually in the CM db, and I also need to test that it's creation timestamp is less than 24 hours old. Yes I know those are two separate things, but I just wanted to give you all the full picture.

I know that they will belong to a specific segment, so I'm thinking that I need to do something like segment_name->custome_field_name->value but maybe I'm barking up the wrong tree ...

Any suggestions or pointers in the general direction I should be going?

Ok, I've figured out how to return one subscriber, based on their email address, ie{list ID}.json? but that's not quite what I want :/ I tried swapping out '?email=' with 'customfield=' but that just returns an 'invalid email address' error.

I would really appreciate if a CM employee could tell me if what I'm trying to do is even possible, because if it's not I don't want to keep hitting my head against it.

Thanks in advance!

Hmmm well it seems like I'm pretty much on my own on these boards ;-) Anyway I think what I'm going to do is send a link in the plaintext email that looks like this[email]&licence=[Licence,fallback=]

That way the user doesn't have to enter anything on the purchase page, and we have the email address and can do a lookup with the CM API to confirm authenticity and time-stamp (which I've still yet to figure out but I think it's well within reach).

That'll definitely work Jonny. As long as you have the email address you can grab all a subscribers custom fields with this method:

@tobyb sorry for the idiotic question, but how do I use $_GET programmatic-ally? Yes if I do what is shown in the link you posted, in a browser address bar, it hits me with the authentication dialog and then gives me the json result, but obviously I need to do it in the code, not manually. I've looked at the sample contained in the php wrapper files, located at /samples/subscriber/get.php, but that is entirely different, and I can see no way to choose json/xml, it simply returns an array (which I'm having zero luck in traversing). Obviously I'm quite green with php :( I'll keep banging my head against it but any pointers in the right direction would be most helpful!
