The tenant is resolved from the JWT and the context/source from the path — NEVER from the body. The body carries connection coordinates plus an OPAQUE credential reference, never a secret. A transport-level fetch failure (the external endpoint is unreachable or rejects the credential) returns 503; per-file intake failures are reported in the response body without failing the batch. ## OpenAPI ````yaml en/openapi/v3-current/matcher.yaml post /v1/imports/contexts/{contextId}/sources/{sourceId}/fetch openapi: 3.1.0 info: title: Matcher APIs description: >- Complete API reference for the Matcher reconciliation engine, providing automated transaction matching between Midaz Ledger and external systems. version: 4.1.0 license: name: Elastic License 2.0 url: https://www.elastic.co/licensing/elastic-license servers: - url: https://matcher.sandbox.lerian.net security: [] paths: /v1/imports/contexts/{contextId}/sources/{sourceId}/fetch: post: tags: - Ingestion summary: Trigger a manual fetch-and-ingest from an external transport description: >- Lists every object matching the supplied transport coordinates (SFTP today) and streams each into the trusted-content ingestion pipeline (dedup + outbox + match-trigger), returning a per-file outcome in fetch order.
