Slack Block Kit Json Schema

Open schema raw file

Schema extracted from https://a.slack-edge.com/bv1-6-8cacda2/block-kit-builder.93ca53691de7cf9d4417.min.js
Probably the url/bundle will change every deploy so you might want to go https://api.slack.com/tools/block-kit-builder, open devtools and search for that file (block-kit-builder) in source tab. Pass some unminify tool and search for "JSON Schema".

PS1: Some block/element types simply does not work, idk why.
PS2: If you want to explore easily, copy the code and paste to the devtools console.

json schema by @lawrencegripper

I also facing an issue that I added the block kit builder code in json file and tried to display the card but empty card is getting displayed.

Anyone landing here, the currently linked version is truncated but the first uploaded revision is complete:

Playing with this more it looks like it's no longer up-to-date

TLDR: With some manual effort and the typescript type information I generated the schema. Here it is for others to use.. Note: It validates an array of blocks for input.

 [
    {
	    "type": "header",
	    "text": {
		    "type": "plain_text",
		    "text": "Pipeline Deployment of Heaven Started 🧵 👇",
		    "emoji": true
	    }
		}
]
