How to associate RingCentral call data and Glip post data by user?

How can I associate the call data from the RingCentral API to the user data in the Glip API. As far as I can tell, the only overlap is the proper names located in the call logs to and from fields (which aren't always present), which can be mapped to an email address and then to a Glip user. This seems like a very indirect way of going about things. Are there ids or anything like that to link the two APIs? Specifically I'd like to know if a call that's coming from or going to a person is also a Glip user in my organization.

RingCentral Call Log API Example

https://developer.ringcentral.com/api-reference#Call-Log-loadCompanyCallLog

GET /restapi/v1.0/account/~/call-log

{
    "uri": "https://platform.devtest.ringcentral.com/restapi/v1.0/account/11111111/call-log?view=Simple&showBlocked=true&withRecording=false&dateFrom=2018-11-09T07:00:00.000Z&page=1&perPage=100",
    "records": [
        {
            "uri": "https://platform.devtest.ringcentral.com/restapi/v1.0/account/11111111/call-log/abcdef0123456789?view=Simple",
            "id": "abcdef0123456789",
            "sessionId": "1234567890",
            "startTime": "2018-11-10T00:52:07.020Z",
            "duration": 11,
            "type": "Voice",
            "direction": "Inbound",
            "action": "Phone Call",
            "result": "Missed",
            "to": {
                "phoneNumber": "+16505550100"
            },
            "from": {
                "phoneNumber": "+12155550101",
                "location": "Philadelphia, PA"
            }
        },

Glip Post API Example

https://developer.ringcentral.com/api-reference#Posts-listGlipGroupPosts

GET /restapi/v1.0/glip/groups/{groupId}/posts

{
  "records":[
    {
      "id":"1542094852",
      "groupId":"155654",
      "type":"TextMessage",
      "text":"",
      "creatorId":"glip-29507587",
      "addedPersonIds":null,
      "creationTime":"2018-05-31T14:45:16.822Z",
      "lastModifiedTime":"2018-05-31T14:45:16.822Z",
      "attachments":null,
      "activity":null,
      "title":null,
      "iconUri":null,
      "iconEmoji":null,
      "mentions":null
    }
  ]
}

Solution

Users are identified by the Call Log extensionId and the Glip personId which have the same value when the user is a company user.

In the RingCentral Call Log API, each user is identified by an extensionId.
- In the Company Call Log API (/restapi/v1.0/account/{accountId}/call-log), you will receive call logs for all users and, to identify calls for each user, you need to query the detailed view by adding the view=Detailed query string parameter and then find the extensionId in the call legs array since multiple users can be present in a call. Each leg will have an extension property with a extensionId and HATEOAS uri property to retrieve information for the user.
- In the User Call Log API (/restapi/v1.0/account/{accountId}/extension/{extensionId}/call-log), the extensionId is explicitly stated in the URL path.
In the Glip API, each user is identified by a personId. The personId appears as the creatorId and in other places in the Glip API.
- When the Glip user is also a RingCentral user, the Glip personId value is the same as the extensionId, e.g. 12345678
- When the Glip user is a guest and not present in the RingCentral account, the Glip personId value is prefixed by glip-, e.g. glip-12345678

Here's an example of a detailed Company Call Log entry:

          "legType":"FindMe"
        }
      ]
    }
  ]
}

To map to a Glip user, just map it to Glip users with the personId that matches the Call Log extensionId.
