Airbyte (including the Connector Builder) does not currently provide a built‑in way to: - upload or configure custom CA certificates per connector, or - globally disable/skip SSL verification for HTTP‑based connectors. This limitation appears across several connectors when dealing with self‑signed or private CA certificates (MongoDB/DocumentDB, Elasticsearch/OpenSearch, GitLab, Google Analytics behind zScaler, etc.), and the official responses consistently state that custom certificates are not supported and that you’d need to patch the connector image or trust store yourself if you want to work around it.[\[Self‑signed Mongo/ES\]](

https://github.com/airbytehq/airbyte/issues/58097) So, for your specific situation with Connector Builder: - There is no documented, supported toggle to “ignore SSL verification” for a Connector Builder HTTP request. - There is no documented way to inject your self‑signed CA into the Connector Builder’s trust store via the UI or standard configuration. Workarounds that have been suggested in similar cases involve customizing the underlying Docker image (e.g., adding your CA to the container’s trust store or patching the connector code), but these are not documented as official steps for the Connector Builder specifically and would require you to maintain a custom image.[\[Self‑signed Mongo/ES\]](

https://discuss.airbyte.io/t/1526) Because the knowledge sources do not include a Connector‑Builder‑specific solution, the most accurate guidance is: - Use a certificate signed by a trusted CA (or have your corporate CA installed at the Docker/host level so the container inherits trust),
or - Build and run a custom Airbyte/Connector‑Builder image with your CA added to the trust store (unsupported but mentioned as the only current workaround for similar SSL issues). If you need an officially supported way to handle self‑signed certs in the Connector Builder, you’d need to open or upvote a GitHub issue so the team can prioritize adding custom CA / SSL configuration for builder‑based connectors.[\[GitLab SSL error\]](
