# Update Content Library Link

**PUT /v1/content-library**

Update the URL or function payload of a Weblink or JS Function content item in your PX Subscription.

Only content items of type LINK, or FUNC_CALL are supported.

Examples: 

| URI   | Results  |
| ----- | -------- |
| PUT /v1/content-library | Update a Weblink URL: `{ "contentId": "abcd1234", "url": "https://example.com" }` |
| PUT /v1/content-library | Update a JS Function payload: `{ "contentId": "abcd1234", "funcPayload": "{\"key\":\"value\"}" }` |

<b>Important:</b> For Weblink types (LINK), provide `url` in the request body. For JS Function types (FUNC_CALL), provide `funcPayload`. The content type is inferred from the `contentId` — only one field is applied per call.
