Laurentiu Gheorghiu commented on billing_address field issue: Are there special considerations for field data when creating orders?

Hi

We had the same problem and we found the error in our case, but I think it same in yours:

billing_address and shipping_address are not Arrays  [ {...} ] , but Objects  {..} . (notice the parentheses)

After correction it works just fine.

We don't use php, but you will figure out which is you sintax.
