Transaction amounts are randomized per request. Returns a single map entry: list of generated docIds as key, list of DE39 response codes as value. **Legacy load-testing endpoint. Use `/v1/batch-transactions` for functional testing.** ## OpenAPI ````yaml json-files/mycore-test-api.openapi.json post /authorizations/requests-batched openapi: 3.0.3 info: version: '1' title: Test API description: > Available in the integration environment.
