How do I send an AJAX request to Twitch?

I have a template for this request saved as a JSON project file:

It doesn't have to be a file, you can simply store this JSON string in a text variable. Then to replace session ID use:

Set jsonString to replace(jsonString, "YOUR_SESSION_ID", extractedSessionID)

Another option is to load (parse) it into JSON object and use this action:

JSON Set value at "transport.session_id" to extractedSessionID

Then how do I format this so that I can use it in the data parameter of the AJAX request?

This should be in Twitch documentation I suppose. If you are using JSON object, you can convert it back to string with JSON.ToCompactString expression.

Thanks - I need to have play around with the JSON manipulation stuff.

But the second part of the query was around how to get something like this example curl request working in the AJAX plugin.

curl -X POST 'https://api.twitch.tv/helix/eventsub/subscriptions' \

-H 'Authorization: Bearer 2gbdx6oar67tqtcmt49t3wpcgycthx' \

-H 'Client-Id: wbmytr93xzw8zbg0p1izqyzzc5mbiz' \

-H 'Content-Type: application/json' \

-d '{

"type": "channel.chat.message",

"version": "1",

"condition": {

"broadcaster_user_id": "12826",

"user_id": "141981764"

},

"transport": {

"method": "webhook",

"callback": "https://your-webhook-handling-server.com",

"secret":"s3cre7"

}

}'

Specifically the -d data part

I need to send a POST request to Twitch's /subscriptions endpoint (using Construct's AJAX plugin) because:

IMPORTANT The EventSub WebSocket server supports only outgoing messages. If you send a message to the server, except for Pong messages, the server closes the connection.

I just need to figure how how to format the data - I think I should be able to do that - especially now I know how to manipulate the templated JSON.

EDIT - I think the flow is:

1. Load the templated JSON from a project file
2. Insert the session ID
3. JSON.ToCompactString
4. URLEncode
