# Event Composition The FHIR Composition id is a powerful identifier and should only be accessible by approved government systems, such as those using `health` or `nationalId` JWT scopes. If you are proposing a new webhook in a feature request, consider the `resourceType` that your service requires, based on the explanation of the FHIR resources in the rest of this page. You should not need to expose the composition id in your mediator if your client service doesnt require it. | Parameter | Sample value | Description | | --------------------- | -------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `target.id` | `bab755e0-7bbd-4d90-b155-352ffa283467` | The unique `id` for the [FHIR resource](https://www.hl7.org/fhir/resource.html) target that this webhook refers to. | | `target.resourceType` | `Composition` | The [FHIR resource](https://www.hl7.org/fhir/resource.html) type associated with the target `id` of this webhook, e.g. `Composition` for a [FHIR Composition](https://www.hl7.org/fhir/composition.html). | #### **URL** You can request the composition payload via the OpenHIM core using an [authentication token](https://github.com/opencrvs/opencrvs.github.io/blob/master/website/docs/technology/technicalInteroperability) and Composition `id`. ``` GET http://openhim-core:5001/fhir/Composition/ ``` NOTE: If the webhook returned a different resourceType, you could do this: ``` GET http://openhim-core:5001/fhir// ``` #### **Request headers** ``` Content-Type: application/json Authorization: Bearer ``` #### **Composition payload** ``` { "identifier": { "system": "urn:ietf:rfc:3986", "value": "BKBQMCD" }, "resourceType": "Composition", "status": "preliminary", "type": { "coding": [ { "system": "http://opencrvs.org/doc-types", "code": "birth-application" } ], "text": "Birth Application" }, "class": { "coding": [ { "system": "http://opencrvs.org/doc-classes", "code": "crvs-document" } ], "text": "CRVS Document" }, "title": "Birth Application", "section": [ { "title": "Birth encounter", "code": { "coding": [ { "system": "http://opencrvs.org/specs/sections", "code": "birth-encounter" } ], "text": "Birth encounter" }, "entry": [ { "reference": "Encounter/af7be33b-3e0c-4012-b894-c32d4bcc5100" } ] }, { "title": "Child details", "code": { "coding": [ { "system": "http://opencrvs.org/doc-sections", "code": "child-details" } ], "text": "Child details" }, "entry": [{ "reference": "Patient/0a92c057-e1a6-476f-918b-7e98cb7479b8" }] }, { "title": "Mother's details", "code": { "coding": [ { "system": "http://opencrvs.org/doc-sections", "code": "mother-details" } ], "text": "Mother's details" }, "entry": [{ "reference": "Patient/5e22eea3-2e61-4dc1-8047-e216b3334c2e" }] }, { "title": "Father's details", "code": { "coding": [ { "system": "http://opencrvs.org/doc-sections", "code": "father-details" } ], "text": "Father's details" }, "entry": [{ "reference": "Patient/5e22eea3-2e61-4dc1-8047-e216b3334c2e" }] }, { "title": "Informant's details", "code": { "coding": { "system": "http://opencrvs.org/specs/sections", "code": "informant-details" }, "text": "Informant's details" }, "text": "", "entry": [ { "reference": "Patient/47a090fa-e7bf-457f-98a6-8f2eb60fef32" } ] }, { "title": "Supporting documents", "code": { "coding": { "system": "http://opencrvs.org/specs/sections", "code": "supporting-documents" }, "text": "Supporting documents" }, "text": "", "entry": [ { "reference": "DocumentReference/11d2b8fc-f875-49cc-96e6-2447ebfc8fc6" } ] }, { "title": "Certificates", "code": { "coding": { "system": "http://opencrvs.org/specs/sections", "code": "certificates" }, "text": "Certificates" }, "text": "", "entry": [ { "reference": "DocumentReference/301ef878-1f94-4979-b660-7ad926dd1941" } ] } ], "subject": {}, "date": "2020-07-02T15:28:34.813Z", "author": [], "meta": { "lastUpdated": "2020-07-02T15:28:35.392+00:00", "versionId": "de12d2df-fac3-4f84-bc85-b665ba12b02f" }, "id": "bab755e0-7bbd-4d90-b155-352ffa283467" } ``` #### **Key payload parameters**
