# Restream an asset with the Wowza Video REST API (1.x legacy API) The Wowza Videoâ„¢ Asset Manager allows users to ingest, store, and tag video content in order to centralize, reuse, amplify, and provide user-friendly access to assets. See Video CMS: What it is and why you need one for more information. Info - This topic only applies to version 1.x of the REST API. - You must obtain a license for the Asset Manager as part of your Wowza Video subscription to add this capability to your account. Contact us for more information. This article demonstrates how to create a live stream associated with your .mp4 using the Wowza Video REST API. ## Before you start You should be familiar with the following concepts: - **API authentication** **methods**. We use JSON web tokens for API authentication. See [Authentication](/docs/wowza-video/about-the-rest-api/authentication) for more information. - **Environment variables**. We use environment variables for the API version and your JWT in the cURL API request examples in this topic to make it easier for you to copy, paste, and run commands in your Terminal or Command Prompt window. If you don't set environment variables for these values, you'll need to manually enter the correct values in the code samples throughout this tutorial. See [Tools for testing the API](/docs/wowza-video/about-the-rest-api/api-overview#tools-for-testing-the-api) for instructions. You should complete the following tasks: - Create an **asset**. See [Upload an Asset with the Wowza Video REST API](/docs/wowza-video/wowza-video-legacy/upload-an-asset) to learn how. ## 1. Retrieve your asset ID Locate your asset ID by sending a `GET` request to the `/assets` endpoint. #### Sample request Endpoint Reference ``` curl -X GET \ -H "Content-Type: application/json" \ -H "Authorization: Bearer ${WV_JWT}" \ -X "${WV_HOST}/api/${WV_VERSION}/assets" ``` #### Sample response The response includes: - A list of assets. You'll need to find the asset you want to restream and record the `id`. ``` { "assets": [ { "id": "1ttmionz", "name": "test1.mp4", "created_at": "2022-03-23T16:56:09.108Z", "updated_at": "2022-03-23T16:56:10.219Z", "published": false, "thumbnail_url": null, "state": "uploading", "processing_percentage": 0.0, "file_size": 0, "playback_url": null, "download_url": null, "file_name": "test1.mp4" }, { "id": "paprtlx9", "name": "guardians_multi.mp4", "created_at": "2022-03-17T16:19:04.908Z", "updated_at": "2022-03-17T16:36:04.779Z", "published": false, "thumbnail_url": "https://storage.googleapis.com/qa-wse-recordings/frP7Drv3/recording_whhvnjyb/whhvnjyb_thumbnail.jpg", "state": "completed", "processing_percentage": 100.0, "file_size": 269788414, "playback_url": "https://cdn3-qa.wowza.com/2/QlRpZ0JNOGxrQW1V/MUdHa29O/hls/lc6jv5jj/playlist.m3u8", "download_url": "https://storage.googleapis.com/qa-wse-recordings/frP7Drv3/recording_whhvnjyb/guardians_multi.mp4", "file_name": "guardians_multi.mp4" } ], "pagination": { "payload_version": 2.0, "total_records": 112, "page": 1, "per_page": 15, "total_pages": 8, "page_first_index": 0, "page_last_index": 14 } } ``` ## 2. Restream your asset Restream your asset by sending a `POST` request to the `/assets/{id}/live_streams` endpoint. You can use the following sample request, making sure to: - Set `id` to the id of the asset returned in Step 1. #### Sample request Endpoint Reference ``` curl -X POST \ -H "Content-Type: application/json" \ -H "Authorization: Bearer ${WV_JWT}" \ -X "${WV_HOST}/api/${WV_VERSION}/assets/{id}/live_streams" ``` #### Sample response The response includes: - An `id` for the live stream that you can use to re-stream an uploaded asset. ``` { "live_streams": { "name": "Restreamed Asset (k9xje4kq)", "id": "i8qsbwvi", } } ``` ## 3. Start a live stream Now that you have created a live stream, you'll need to start it. See [Quickly start a live stream](/docs/wowza-video/quick-start/start-live-streaming) for more information.
