Where is the JSON schema for Slack Block Kit?

The block kit builder (slack.com) is able to validate json input, so the schema is available somewhere :

But the schema (github.com) I found in Slack docs has no definitions for the blocks:

        "blocks": {
        "description": "This is a very loose definition, in the future, we'll populate this with deeper schema in this definition namespace.",
        "items": {
            "additionalProperties": true,
            "properties": {
                "type": {
                    "type": "string"
                }
            },
            "required": [
                "type"
            ],
            "type": "object"
        },
        "title": "Block Kit blocks",
        "type": "array"
    },

So, is this available anywhere ?

Thank you

Solution

  • I don't think that block schema is available anywhere right now. There is a pending issue on Slack's github repo that speaks about exactly the same problem. The last official response was sent more than a year ago.
