If you changed your Help Center selection recently, remember the new selection only applies to future syncs — existing indexed content from deselected Help Centers needs to be removed manually. ## Common scenarios | Symptom | Likely cause | Fix | | --------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Help Center picker shows "Failed to load Help Centers"** | The API key doesn't have **Knowledge Base: Read** scope, or is invalid | Re-generate the token in the [Front Developer Portal](https://dev.frontapp.com/docs/create-and-revoke-api-tokens) with the right scope. Paste it — the picker auto-retries. | | **An internal Front article is showing in customer-facing replies** | Either the Help Center's type in Front isn't set to `internal`, or the article was once in a public HC and got moved | Confirm the Help Center `type` in Front. If it's `internal`, trigger a re-sync — OpenCX will flip the visibility. If it's public but this specific article shouldn't be, override visibility per-article in [AI Instructions](https://platform.open.cx/ai-instructions) via the eye icon. | | **I deselected a Help Center but its articles still appear** | Deselection filters future syncs; existing items stay indexed until removed | Open AI Instructions, filter by **Front** source and the Help Center name, bulk-delete. Future syncs won't re-fetch those articles. | | **The picker's checkboxes resolve to a different count than I saved** | The connection picks up any new Help Centers you've added in Front since the last save, and applies the previously saved `allowed_knowledge_base_ids` filter to unchanged ones | Open the source, review the list, update selections, save. The picker shows all currently-accessible Help Centers from the token. | | **Drafts from Front appear in the AI's answers** | Draft articles sync as `internal` but can still surface in agent-facing tools | If that's unwanted, publish the article in Front (moves it to `public`) or override visibility in AI Instructions. | | **None of the above** | — | Contact support with the connection ID and the HC names you expected vs. see. | ## Limits | | Value | | ------------------------ | ------------------------------------------------------------------ | | **Selective scoping** | Per-Help-Center checkboxes; no sub-category scoping | | **Multi-account** | Not supported today | | **Sync cadence** | Airbyte polling — typically every few hours | | **Deselection behavior** | Filters future syncs only; existing items must be manually deleted | *** ## Related Documentation Re-check credentials and Help Center picker.
