Build a custom Airbyte source connector with the low-code Connector Builder YAML manifest

Steps
Start from the manifest's top-level structure: version, definitions, streams, check, and spec.
Define each API resource as a stream in the streams list, backed by a DeclarativeStream whose retriever (typically a SimpleRetriever) fetches records.
Configure the retriever's requester (an HttpRequester) with the base URL, path, HTTP method, and auth — this is what actually issues each HTTP request.
Add a record selector to the retriever to pull the list of records out of the raw HTTP response body, and a paginator if the API returns multiple pages.
Use a partition router on the retriever if the stream needs to fan out over a list of parent values (e.g. one request per account ID) rather than a single flat request.
Validate the manifest with the connector's check block before wiring it into a real connection, so auth/config errors surface early instead of failing mid-sync.
Known gotchas
The manifest separates "how to ask" (requester) from "how to read the answer" (record selector) — a connector returning 200 OK with an empty stream is often a record-selector JSONPath mismatch, not an auth problem.
Airbyte's older Configuration API has been deprecated in favor of the current public API — connector-registration automation written against older API examples may target endpoints that no longer exist.
