MailChimp Interested Value in “Group” always false after “subscribing”

问题

I send over proper json formatted code, according to v2 api docs:

lists/subscribe.json

"GROUPINGS":[{"id":removed_id,"name":"grouping_name","groups":["group_name"]}]

I get back information about a member... It does not say they are interested in that group name..

lists/member-info.json

"GROUPINGS":[{"id":removed_id,"name":"grouping_name","form_field":"hidden","groups":
[{"name":"group_name","interested":false},{"name":"other_group_name","interested":false},
{"name":"other_group_name2","interested":false},{"name":"other_group_name3","interested":false}]}]

I do not understand how I can get these users to show up as "subscribed" to a group within my grouping. I have been trying for nearly 5 hours now. I have tried:

making sure the groups: value is an [] array.
trying out making that value a string (which surprisingly did not throw errors)
capitalizing "GROUPINGS" when sending it in merge_vars
not capitalizing "groupings" when sending in merge_vars
using the lists/update-member.json method to update these groups
using the name of my interest group instead of grouping in the grouping array.
using the option replace_interests on both true and false

In conclusion,

I had to email mailchimp a support ticket. Without changing my code at all - it works this morning. Interestingly enough, mailchimp was experiencing many issues yesterday with servers being down and alleged email hackings.

To be clear about which version of my code worked - following the API exactly for v2.

It was an error on mailchimp's end.

{
   "id":"MY LIST ID",
   "email":{
      "email":"THE EMAIL TO SUBSCRIBE"
   },
   "merge_vars":{
      "GROUPINGS":[
         {
            "id":THE GROUPING ID,
            "groups":[
               "THE NAME OF MY GROUP"
            ]
         }
      ]
   },
   "double_optin":false,
   "replace_interests":true,
   "apikey":"MY API KEY"
}

Also, in case you are curious, replace_interests is true when the groups you send are supposed to replace existing groups the subscriber is interested in. False indicates that the groups you pass should be added to the interest groups.

If you are updating a member (method: lists/update-member), it may be best to set replace_interests to false just to make sure it does not overwrite your existing interest groups (possibly with blank groups). The default value for it is true, so this could be another place prone to error.
