Creating a schema from event JSON in Amazon EventBridge
If you have the JSON of an event, you can automatically create a schema for that type of event.
To create a schema based on the JSON of an event
Open the Amazon EventBridge console at https://console.aws.amazon.com/events/
. -
In the navigation pane, choose Schemas and then choose Create schema.
-
(Optional) Select or create a schema registry.
-
Under Schema details enter a name for your schema.
-
(Optional) Enter a description for the schema you created.
-
For Schema type, choose OpenAPI 3.0.
You can't use JSONSchema when you create a schema from the JSON of an event.
-
Select Discover from JSON
-
In the text box under JSON, paste or drag the JSON source of an event.
For example, you could paste in the source from this AWS Step Functions event for a failed execution.
{ "version": "0", "id": "315c1398-40ff-a850-213b-158f73e60175", "detail-type": "Step Functions Execution Status Change", "source": "aws.states", "account": "012345678912", "time": "2019-02-26T19:42:21Z", "region": "us-east-1", "resources": [ "arn:aws:states:us-east-1:012345678912:execution:state-machine-name:execution-name" ], "detail": { "executionArn": "arn:aws:states:us-east-1:012345678912:execution:state-machine-name:execution-name", "stateMachineArn": "arn:aws:states:us-east-1:012345678912:stateMachine:state-machine", "name": "execution-name", "status": "FAILED", "startDate": 1551225146847, "stopDate": 1551225151881, "input": "{}", "output": null } }
-
Choose Discover schema.
-
EventBridge generates an OpenAPI schema for the event. For example, the following schema is generated for the preceding Step Functions event.
{ "openapi": "3.0.0", "info": { "version": "1.0.0", "title": "StepFunctionsExecutionStatusChange" }, "paths": {}, "components": { "schemas": { "AWSEvent": { "type": "object", "required": ["detail-type", "resources", "detail", "id", "source", "time", "region", "version", "account"], "x-amazon-events-detail-type": "Step Functions Execution Status Change", "x-amazon-events-source": "aws.states", "properties": { "detail": { "$ref": "#/components/schemas/StepFunctionsExecutionStatusChange" }, "account": { "type": "string" }, "detail-type": { "type": "string" }, "id": { "type": "string" }, "region": { "type": "string" }, "resources": { "type": "array", "items": { "type": "string" } }, "source": { "type": "string" }, "time": { "type": "string", "format": "date-time" }, "version": { "type": "string" } } }, "StepFunctionsExecutionStatusChange": { "type": "object", "required": ["output", "input", "executionArn", "name", "stateMachineArn", "startDate", "stopDate", "status"], "properties": { "executionArn": { "type": "string" }, "input": { "type": "string" }, "name": { "type": "string" }, "output": {}, "startDate": { "type": "integer", "format": "int64" }, "stateMachineArn": { "type": "string" }, "status": { "type": "string" }, "stopDate": { "type": "integer", "format": "int64" } } } } } }
-
After the schema has been generated, choose Create.
