Here we explore a simplified sample workflow for identifying the status of a snapshot’s changes using the tracking endpoint(s).
1

Send Snapshot

First, send a snapshot to Noyo:
Request
curl --request POST \
     --url https://fulfillment.noyo.com/api/v1/groups/{group_id}/member_snapshots
You’ll receive the ID of the created snapshot:
Response
{
  "id": "7bea80ac-499d-560b-5512-60be9e2349cb",
  "created": 1656030390,
  ...
}
If you use webhooks, you’ll receive difference.created events for every change or update in the snapshot.
2

Retrieve differences

We then call the tracking endpoint to retrieve a field-level list of differences associated with the snapshot. These differences will either be pending changes introduced by the snapshot, or discrepancies raised during round-trip confirmation. They can be pulled at any time and will always reflect their real-time status.For this example, we’ll assume your snapshot included one new item– enrolling a dependent in vision coverage.Call the differences endpoint using the snapshot ID as a query parameter:
Request
curl --request GET \
     --url https://tracking.noyo.com/api/v1/differences?member_snapshot_id=7bea80ac-499d-560b-5512-60be9e2349cb
The response returns one difference (pending change)– the carrier doesn’t have an enrollment in the snapshot (that’s what is being processed)
Response
[
    {
        "id": "da5ec83e-450f-4eee-ad6c-8b6d60d41b88",
        "resolved": null,
        "discrepancy_time": null,
        "group_id": "a1b6fe36-ccc5-41e3-bcc0-e6488d7e031e",
        "carrier_id": "2d370e0e-fd73-45e0-8828-796d2cacaeef",
        "employee_id": "a9c01d76-019c-4c44-b414-a832246c014d",
        "object_type": "dependent",
        "object_id": "d0e180e6-fafc-441e-8ac4-08d9a9fe4657",
        "impact_score": 5,
        "difference_classification": "missing_from_carrier",
        "difference_type": "missing_ie",
        "sources": [],
        "fields": [
            {
                "key": "object",
                "platform_value": {
                    "individual_id": "d0e180e6-fafc-441e-8ac4-08d9a9fe4657",
                    "line_of_coverage": "vision",
                    "member_first_name": "Jade",
                    "member_last_name": "Cornwall",
                    "member_type": "dependent",
                    "plan_id": "9302a1db-bed5-4be6-96f5-c51371cc96a3"
                },
                "carrier_value": null
            }
        ]
    }
]

Track over time

Fast forward a day or two. The carrier has enrolled the dependent successfully, but with a later effective date due to their rules and limitations. The tracking endpoint will surface this information. Let’s call it again:
Request
curl --request GET \
     --url https://tracking.noyo.com/api/v1/differences?member_snapshot_id=7bea80ac-499d-560b-5512-60be9e2349cb
We now get an updated response. The original difference is now marked as resolved, meaning the carrier successfully enrolled the dependent. There’s a new discrepancy raised noting the difference in effective start date. (some payload fields omitted for brevity)
Response
[
    {
        "id": "da5ec83e-450f-4eee-ad6c-8b6d60d41b88",
        "resolved": 1708295864,
        "discrepancy_time": null,
        "impact_score": 5,
        "difference_classification": "missing_from_carrier",
        "difference_type": "missing_ie",
        "fields": [
            {
                "key": "object",
                "platform_value": {
                    "individual_id": "d0e180e6-fafc-441e-8ac4-08d9a9fe4657",
                    "line_of_coverage": "vision",
                    "member_first_name": "Jade",
                    "member_last_name": "Cornwall",
                    "member_type": "dependent",
                    "plan_id": "9302a1db-bed5-4be6-96f5-c51371cc96a3"
                },
                "carrier_value": null
            }
        ]
    },
    {
        "id": "95b8611b-15f6-46c6-8bb1-353dcd52e3fb",
        "resolved": null,
        "discrepancy_time": 1703098579,
        "impact_score": 4,
        "difference_classification": "field_mismatch",
        "difference_type": "ie_effective_start_date",
        "fields": [
            {
                "key": "effective_start_date",
                "platform_value": "2024-08-22",
                "carrier_value": "2024-09-01"
            }
        ]
    }
]
If you use webhooks, you will have received a few events along the way:
  • For the dependent enrollment, a difference.resolvedevent (in addition to the original creation event)
  • For the effective date discrepancy, both a difference.created and difference.discrepancy event
  • For the snapshot, both a member_snapshot.status_change event and a member_snapshot_carrier_fulfillment_status.status_change event
