## Logical Model: Smart Health Link Payload (DRAFT)

Official URL: http://smart.who.int/trust/StructureDefinition/SmartHealthLinkPayload | Version: 1.1.5
Draft as of 2024-12-20 | Computable Name: SmartHealthLinkPayload

Smart Health Link Payload (DRAFT)

This logical model was taken from the SMART Health Link documentation https://docs.smarthealthit.org/smart-health-links/spec#construct-a-shlink-payload as if 30 November 2023.

A [[ SMART Health Link]] is generated from this payload according to the algorithm documented here https://docs.smarthealthit.org/smart-health-links/spec#example-shlink-generation to create a

SmartHealthLinkPayload |  | 0..* | Base | Smart Health Link Payload (DRAFT) Instances of this logical model are not marked to be the target of a Reference
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 SHL 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 SHLink is intended for long-term use and manifest content can evolve over time P Indicates the SHLink requires a Passcode to resolves U Indicates the SHLink's url resolves to a single encrypted file accessible via GET, bypassing the manifest. 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 SHLink.
v |  | 0..1 | string | Optional. Integer representing the SHLinks protocol version this SHLink conforms to. MAY be omitted when the default value (1) applies.
