So, I am using this page as a reference for retrieving subscriptions for an array of mobile numbers:
https://code.exacttarget.com/api/contacts-subscriptions
The page seems to differ from other API pages in that the mobileNumber array isn't named the same as the other API calls that take an array of numbers. The other API guides have it named as mobileNumbers.
Also, the API request doesn't show "access_token" as a parameter for the API call. I added the access_token at the end of my JSON request but keep getting a HTTP 400 error. Other API calls that I make work just fine, it's only the call I am making to the following URL that has an issue:
https://www.exacttargetapis.com/sms/v1/contacts/subscriptions?access_token=sometoken
Any help would be greatly appreciated!
