Batch/Transaction
Do multiple operations in one call
Transaction interaction allows performing several interactions using one http request. There are two types of transaction interaction (type is specified by field
type): batch and transaction. The first one just executes requests one by one, the second one does the same, but roll backs all changes if any request fails.POST [base]
The body of such request contains one resource of type Bundle, which contains field entry with an array of interactions, for example: \
POST /
Accept: text/yaml
Content-Type: text/yaml
type: transaction
entry:
- resource:
id: admin
email: "[email protected]" # Change this value
password: "password" # Change this value
request:
method: POST
url: "/User"
- resource:
id: SPA
redirect_uri: http://localhost:4200
request:
method: POST
url: "/Client"
- resource:
engine: json-schema
schema:
type: object
required:
- user
request:
method: POST
url: "/AccessPolicy"
Each element of the entry array contains a resource field (body of the request) and a request field (request line in terms of the HTTP request).
resource: # not needed for DELETE and GET
# resource here
fullUrl: "something-here" # needed if you want to refer
# the resource inside bundle
request:
method: POST # POST/GET/PUT/DELETE
url: "/ResourceType" # request url
Transaction interaction is processed in the order provided in a bundle, each interaction is executed one by one. It differs from the FHIR transaction processing rules.
For
type: batch references to resources inside a bundle won't be resolved.For
type: transaction before processing interactions, all references in a resource will attempt to resolve. In this example ProcedureRequest will refer to a newly created patient:POST /
Accept: text/yaml
Content-Type: text/yaml
type: transaction
entry:
- resource:
resourceType: Patient
fullUrl: urn:uuid:<uuid-here>
request:
method: POST
url: "/Patient?_identifier=mrn:123"
- resource:
resourceType: Encounter
status: proposal
subject:
uri: urn:uuid:<uuid-here>
request:
method: POST
url: "/Encounter"
You can provide a full Url with value like
"urn:<uuid-here>" and reference to the resource created by such interaction using ref: {uri: "urn:<uuid-here>"}. Those references are temporary and will be translated to valid Aidbox references when interaction entry is processed by a server.You SHALL NOT refer resource, which is created later using conditional operations!
If you have multiple entries with the same resource id, aidbox will execute them one by one and thus you are able to create a resource with a history in within a single transaction:
POST /
Accept: text/yaml
Content-Type: text/yaml
resourceType: Bundle
type: transaction
entry:
- request: {method: PUT, url: 'Patient/pt-1'}
resource: {birthDate: '2021-01-01'}
- request: {method: PUT, url: 'Patient/pt-1'}
resource: {birthDate: '2021-01-02'}
- request: {method: PUT, url: 'Patient/pt-1'}
resource: {birthDate: '2021-01-03'}
Request

total: 3
entry:
- resource: {birthDate: '2021-01-03', id: pt-1, resourceType: Patient}
