The following code examples show how to create Subscription payloads.

**EventBridge**

Subscription with `event-bridge` channel **and** `id-only` payload type.

```
{
  "resourceType": "Subscription",
  "meta": {
    "profile": [
      "http://hl7.org/fhir/uv/subscriptions-backport/StructureDefinition/backport-subscription"
    ]
  },
  "status": "requested",
  "end": "2026-07-31T05:38:17.2404292+00:00",
  "reason": "Test subscription for walkthrough",
  "criteria": "https://healthlake.<AWS_REGION>.amazonaws.com/datastore/<datastoreId/r4/SubscriptionTopic/<your topic id>",
  "_criteria": {
    "extension": [
      {
        "url": "http://hl7.org/fhir/uv/subscriptions-backport/StructureDefinition/backport-filter-criteria",
        "valueString": "Encounter?subject=Patient/<patient id>"
      }
    ]
  },
  "channel": {
    "type": "event-bridge",
    "endpoint": "arn:aws:healthlake:eu-west-2:{{111122223333}}:event-bus/FhirSubscriptions-bus",
    "payload": "application/fhir+json",
    "_payload": {
      "extension": [
        {
          "url": "http://hl7.org/fhir/uv/subscriptions-backport/StructureDefinition/backport-payload-content",
          "valueCode": "id-only"
        }
      ]
    }
  }
}
```

Subscription with `event-bridge` endpoint **and** `full-resource` payload type.

```
{
  "resourceType": "Subscription",
