Read

The read interaction accesses the current version of a resource.

GET [base]/[type]/[id]

On success, Blaze returns the resource with a 200 OK. The response contains an ETag header with the version id of the resource and a Last-Modified header with the transaction time of its last change:

HTTP/1.1 200 OK
Last-Modified: Tue, 24 Jun 2025 09:03:22 GMT
ETag: W/"23"

The version id in the ETag header is identical to meta.versionId of the returned resource and can be used in an If-Match header of a subsequent update to detect concurrent modifications.

Handling Errors

Status Code	Description
400 Bad Request	The id given in the URL is invalid. Ids are restricted to 64 characters of A-Z, a-z, 0-9, - and ..
404 Not Found	No resource with the given id exists.
410 Gone	The resource existed but is deleted. The ETag and Last-Modified headers refer to the deletion. Past versions are still accessible via the versioned read and history interactions.

All error responses contain an OperationOutcome with details in the body.

Conditional Read

Conditional reads via the If-Modified-Since or If-None-Match headers are not implemented yet. Accordingly Blaze advertises CapabilityStatement.rest.resource.conditionalRead as not-supported.
