# External IDs

Add external identifiers onto Pylon accounts so you can reference them with your own IDs. Especially useful to associate issues and contacts made from the [Chat Widget](https://docs.usepylon.com/pylon-docs/chat-widget) with the proper account. External IDs can be modified or added from the account sidebar or account overview page. 

For example, attach your own internal organization or customer identifier(s) onto accounts as external IDs.

See the [PATCH /accounts/{id}](https://docs.usepylon.com/pylon-docs/developer/api/api-reference/accounts) endpoints for being able to set external IDs on accounts!
