You may use the
AdwordsUserListService to upload the mobile advertisement IDs. To be able to upload the data (you should be whitelisted), you will need to put the ids in the
mobileId field of the
Member object. You may check this
sample code in Ruby for reference. Though the sample code uses email address, you may use this as reference to upload the mobileIds. Let me know if you have further clarifications.
