I’m a total beginner using Curl commands - need urgent help!

I’m running it using Windows Command prompt ConEmu:

C:\Users\User\>curl -H “wsc-api-key: aaaa” ^

More? -H “wsc-access-key: aaaa” ^

More? -H “Content-Type: application/json” ^

More? -X “POST” “[https://api.cloud.wowza.com/api/v1.2/stream\_targets/ull](https://api.cloud.wowza.com/api/v1.2/stream_targets/ull)” ^

More? -d {“ull\_stream\_target”: {“name”: “ULLStream”,“source\_delivery\_method”: “push”,}}’

Error here:

{“meta”:{“status”:400,“code”:“ERR-400-InvalidJSON”,“title”:“Invalid JSON Error”,“message”:“The JSON data you tried to push isn’t valid. 822: unexpected token at ’ {name: ^ curl: (3) URL using bad/illegal format or missing URL curl: (3) unmatched close brace/bracket in URL position 6: push,}}’ ^{ull\_stream\_target:’”,“description”:"",“links”:[]}}curl: (3) unmatched brace in URL position 1: {replace1} {replace2} {replace3} {replace4} {replace5} {replace6}

Thanks for using the forums @Sean Teo and I think I have a video that may help you with the correct format. Let me know if this helps you. It gives examples of the CURL command for ULL.

Also, be sure to experiment and copy and paste code from the Cloud Sandbox.

-just make sure you remove “sandbox” when you paste any code.
