   - To sync multiple organizations, list them in your port mapping under `organizations`.

+    createMissingRelatedEntities: true
+    enableMergeEntity: true

   - If `organizations` are not specified, the integration will sync all organizations the classic PAT is scoped to.
 - Precedence: if `githubOrganization` is set in the environment variables or config and `organizations` are listed in port mapping, the integration syncs only the `githubOrganization` (single‑org behavior).
 - Performance: syncing multiple organizations increases API calls and may slow down the integration.

-#### Cleanup after restricting organizations
-
-If you initially synced multiple organizations (e.g., on a first‑time install before your mapping was ready) and later restrict organizations in your mapping, set `entityDeletionThreshold: 1` temporarily and resync to ensure previously ingested, now‑unwanted entities are deleted. Revert the threshold afterwards (default ≈ 0.9) or remove completely.

 ### Create access token
 
 To allow Port to fetch data from your GitHub Organization(s), you need to create an access token. Port supports two types of tokens for authentication: personal access tokens and GitHub app installation tokens.
