New(er) API documentation

TheGamer-

I've been trying to find some documentation for the new(er) api (api.scratch…), but what I could find didn't have many of the features of the old one shown (ie posting comments, following etc). Is there a topic for this somewhere or have they just not been migrated (yet?). Sorry if I've just managed to miss it somehow

Those just haven't been migrated yet.

The official Scratch API documentation is here; I sort-of not-really maintain an unofficial wiki here.

@_nix Is there any way to read/write data to/from the backpack?

Do the new APIs have CORS? The scratchblocks generator is sad

Just self host crossorigin.me, or use http://crossorigin.mooredrive.pw/

Not with the new API, I don't think… but you can use the old API.

GET https://scratch.mit.edu/internalapi/USERNAME/get/
with session cookie

and

POST https://scratch.mit.edu/internalapi/USERNAME/set/
with X-CSRFToken and session cookie and JSON payload as body

Thanks, but that didn’t answer my question. I am aware of crossorigin.me

Which one are you using, get or set? What code are you currently trying? Where are you running the code?

alert("test");
$.get("https://scratch.mit.edu/internalapi/NitroCipher/get/", function(data, status){
    alert("Data: " + data + "\nStatus: " + status);
});
alert("test2");

I have a button event that triggers this in a userscript. Both alerts surrounding the get function properly.

Excuse me, that was a mistake on my part

The get request is actually

GET https://scratch.mit.edu/internalapi/backpack/NitroCipher/get/

How would I add this:

{"type": "script", "name": "Exported from Resurgence", "scripts": [[["procDef", "color %c", ["color"], [""], false]]]}

to the backpack?

Okay, so you'll want to extract the CSRF middleware token. You can find it in document.cookie, and do some RegExes or something to extract it.

POST https://scratch.mit.edu/internalapi/backpack/NitroCipher/set/

The body you will want is your JSON.

You will need to add this header

X-CSRFToken: TOKENHERE

And that should work.

How would all of this look in JS? (I am a noob dev)

Another mistake from me.. you're supposed to use the CDN server for setting. I'm unsure, but I think the following should work.

$.ajax({
    url: "https://cdn.scratch.mit.edu/internalapi/backpack/NitroCipher/set/",
    headers: {
         "X-CSRFToken": document.cookie.match(/scratchcsrftoken=([^;]+)/)[1]
    },
    data: JSON.stringify({"type": "script", "name": "Exported from Resurgence", "scripts": [[["procDef", "color %c", ["color"], [""], false]]]})    
})

I'm basing all this from https://github.com/trumank/scratch-api/blob/master/scratchapi.js

Will this add it to the backpack? Or replace the current backpack data?

Uh, it shouldn't be sending a request to the CDN server. I have no idea how that happened. It works though so I'm not gonna change it right now.

It will replace the entire backpack.

Whoops! You need to stringify an array containing the backpack, I think; and not the individual item. Perhaps that's the reason why it's not working?

However, I'm interested what you mean by “won't post”. Do you mean it returns a status code other than 200; or literally a POST request isn't being made. If the latter, is another verb being used, or is no request being sent at all?
