Slack Blocks - what am I missing

Hm, could you provide some screenshots of the end result and links to the documentation you’re working with?  Would love to help but need more details!

Hi ​@Graham Reed ,

There is not a way to create blocks in Slack using Airtable’s built- in Slack integrations.

However, if you know JavaScript, you can write your own custom JavaScripts to accomplish this.

For an easier way of doing this that doesn’t require writing JavaScript code, you can turn to Make’s advanced automations which DOES support Slack blocks.

Check out the screenshot below.

The only issue here is that if you’ve never used Make before, it may take you a while to learn it, so I’ve assembled a bunch of Make training resources in this thread. For example, here is one of the ways that you can instantly trigger a Make automation from Airtable. 

Hope this helps!

If you’d like to hire the best Airtable consultant to help you with anything Airtable-related, please feel free to contact me through my website: Airtable consultant — ScottWorld

I sent off test and managed to get these:

And these are the previews from the docs, so I think this is what you’re looking for?
 

Here’s the code:
 

let token = input.secret("SLACK_TOKEN")

let response = await fetch("https://slack.com/api/chat.postMessage", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${token}`,
    "Content-Type": "application/json; charset=utf-8"
  },
  body: JSON.stringify({
    channel: "general",
    "blocks": [
      {
        "type": "section",
        "text": {
          "type": "mrkdwn",
          "text": "This is a section block with a button."
        },
        "accessory": {

  })

let result = await response.json();
console.log(result);
output.set('result', result);
