Find and delete Discord webhook message - http

Question

I'm using a Discord webhook to send information which may later be invalidated, so I want to be able to delete it. To do this i use these endpoints:
First i make a post request to send a message:
POST /webhooks/{webhook.id}/{webhook.token}
And then i want to do a delete request to remove the message again:
DELETE /webhooks/{webhook.id}/{webhook.token}/messages/{message.id}
However I don't have the ID of the message i want to delete, since no response is given to the first POST request which is always an empty 204 response. Is it possible to get the message id?
Any help would be appreciated.

Per this reddit post:
If you need to reference a message ID of a webhook message you sent, you can add ?wait=true to the end of the URL which will give you the message data (including the ID) instead of a 204 (No Content) when you don't include the query parameter.
So if you send your normal POST request to your url like this: POST /webhooks/{webhook.id}/{webhook.token}, add ?wait=true to the end of that. Then you will get back data like this:
{
"id": "MESSAGEID",
"type": 0,
"content": "This is a test",
"channel_id": "CHANNELID",
"author": {
"bot": true,
"id": "AUTHORID",
"username": "USERNAME",
"avatar": "AVATARID",
"discriminator": "0000"
},
"attachments": [],
"embeds": [],
"mentions": [],
"mention_roles": [],
"pinned": false,
"mention_everyone": false,
"tts": false,
"timestamp": "2021-11-13T18:10:24.412000+00:00",
"edited_timestamp": null,
"flags": 0,
"components": [],
"webhook_id": "WEBHOOKID"
}
