"Save Tracks for User" example not working with cURL

[Nohanna]

I just tried to use the example in https://developer.spotify.com/documentation/web-api/reference/library/save-tracks-user/ and this was not working as expected.

I just did a copy/paste (and replaced my Authorization header of course) and I got an error 400 "Malformed json payload".

Hey @Nohanna, thanks for coming to the Community for help!

I'd love to take a closer look at this. Could you tell me a bit more about the request you're making with cURL, if possible, could you send over the full request details? That way, I'll be able to replicate this and dive into what might be going on here. Keep me in loop!

Have a good one,

Hubo

Hi Hubo!

Sure, there it is:

curl -i -X PUT "https://api.spotify.com/v1/me/tracks" -H "Authorization: Bearer my_token" -H "Content-Type: application/json" --data "{ids:[\"5ZVujHtwnsqFJvLnqRSdch\"]}"

        "message" : "Malformed json payload"
    }
}

I tried with another track ID but it is also not working with the example in the docs! 🙂
I was wondering if it was due to an update of the endpoints because I checked the new version of the docs (cf. https://developer.spotify.com/documentation/web-api/reference-beta/#endpoint-save-tracks-user) and I couldn't find Body Parameters here, only Query Parameters.

But I tried with my app with a body and it is working, so I'm not sure what is going on.
