# 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](/pylon-docs/chat-widget/overview.md) 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}](/pylon-docs/developer/api/api-reference/accounts.md) endpoints for being able to set external IDs on accounts! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.usepylon.com/pylon-docs/developer/api/external-ids.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
