In addition to my previous questions, i have one more:
i see a lot of fields in the api documentation, but i dont know where to find them in dfp. For example, i know if i enter a PO number in dfp under Optional order fields, i will be able to retrieve that info thru type Order (v201302), field poNumber. But in type Company (v201302), i see a field called externalId, but where is this field in dfp itself? If i want to manually add an advertiser id in the externalId field in dfp, how would i do it?
p.s. - i will be using php.
thank you.
