The
Customer.io source connector does work in Airbyte, but it is a
community / Faros‑maintained connector, not an officially supported Airbyte connector. From the docs: - The
Customer.io source is explicitly marked as maintained by Faros AI and lives in their repo. [[
Customer.io source](
https://docs.airbyte.com/integrations/sources/customer-io)] - Airbyte’s docs list the Faros TypeScript CDK and connectors as
community maintained and “not officially supported” by Airbyte; issues should be raised with the Faros project. [[Community CDKs](
https://docs.airbyte.com/platform/connector-development#community-maintained-cdks)] - A forum thread about a Faros‑maintained Jira source shows Airbyte staff directing users to raise issues on the Faros GitHub rather than Airbyte’s, reinforcing that Airbyte doesn’t debug those connectors. [[Jira + Faros](
https://discuss.airbyte.io/t/3106)] So: 1.
Yes, you can use the Customer.io source in Airbyte OSS 1.4, but: - Airbyte itself does not guarantee support or fixes. - If credentials fail or config validation is broken, you’re expected to open an issue in the Faros AI connectors repo:
https://github.com/faros-ai/airbyte-connectors/issues/new. [[
Customer.io source](
https://docs.airbyte.com/integrations/sources/customer-io)] 2. For your specific “enter creds and it fails” problem, the knowledge sources don’t include error details or troubleshooting for this connector, so I can’t say exactly why it’s failing. The docs only state that you need a
Customer.io App API Key in the
app_api_key
field. [[
Customer.io source](
https://docs.airbyte.com/integrations/sources/customer-io)] If the same config works directly against
Customer.io’s API but fails in Airbyte, the next step is to: - Double‑check you’re using an
App API Key (not Track API key, etc.), and - Open an issue in the Faros AI repo with: - Airbyte version (1.4.x), - Connector name/version (
source-customer-io
and its version), - Full error message and screenshot.
