If you want bidirectional integrations, vendors must subscribe to a resource to receive immediate updates on the resource. Current supported resources are here: https://docs.elationhealth.com/reference/webhooks.
When a resource is saved/deleted/signed off, an HTTP/POST request is sent to your target URL.
The target URL should accept a JSON string in the POST body of the request.
The subscription object looks like the following:
{
"id": 123,
"resource": "patients", // The resource for this object.
"target": "https://requestb.in/18pqnk11", // Target URL where we would send the POST request on new events
"created_date": "2017-01-01T01:05:00Z",
"deleted_date": null,
"signing_pub_key": "abcQINrsOkKXRwNrZ5zemkHqcM5gwmnwRZOKO8YXV7Q="
}
