| Name | Flags | Card. | Type | Description & Constraints |
|---|---|---|---|---|
  HealthLinkPayload | 0..* | Base | Health Link Payload (DRAFT) | |
  url | 1..1 | string | url | |
| key | 1..1 | string | Decryption key for processing files returned in the manifest. 43 characters, consisting of 32 random bytes base64urlencoded. | |
| exp | 0..1 | string | Optional. Number representing expiration time in Epoch seconds, as a hint to help the Health Link Receiving Application determine if this QR is stale. (Note: epoch times should be parsed into 64-bit numeric types.) | |
| flag | 0..1 | string | Optional. String created by concatenating single-character flags in alphabetical order: 'L' indicates the Health Link is intended for long-term use and manifest content can evolve over time; 'P' indicates the Health Link requires a Passcode to resolves; and 'U' indicates the Health Link's url resolves to a single encrypted file accessible via GET, bypassing the manifest and SHALL NOT be used in combination with P. | |
| label | 0..1 | string | Optional. String no longer than 80 characters that provides a short description of the data behind the Health Link. | |
| v | 0..1 | string | Optional. Integer representing the Health Links protocol version this Health Link conforms to. MAY be omitted when the default value (1) applies. | |
 type | 0..1 | code | Classifying type code to distinguish different types of health links. If not present then the Health Link is a SMART Health Link. | |
