**Hi everyone! I could really use a hand with this.**

I’m trying to send Slack messages from my Glide app and have run into a wall. Here’s the situation:

1. **Setup so far**

- Created a Slack app and enabled an **Incoming Webhook** for one specific channel.
- Copied the webhook URL and pasted it into Glide’s **Trigger Webhook** action.

1. **What already works**

- In **Request body** I set
  - **Title (key)** → text
  - **Value** → “hello, world”

- Slack receives the plain-text message just fine.

1. **What fails**

- I want to send **Block Kit** JSON (so the message has sections, fields, etc.).
- Any time I try to put a key like blocks (or payload) with the JSON as the value, Glide returns:

```auto
Trigger webhook: Request failed with status 400

```

1. **Question**

- Has anyone successfully posted **Block Kit** messages to Slack using Glide’s **Trigger Webhook**?
- Do I need a different body format, a special header, or maybe switch to Slack’s chat.postMessage endpoint instead of the incoming webhook?

Any pointers or examples would be hugely appreciated. Thanks in advance!

I have never succeeded with the native integration. Everytime I need to do a Slack block, I resort to using Make/n8n.

Thanks for the reply! I tried using the native integration, but it will not let me insert blocks - maybe I do something wrong with the formatting.

My problem came using the Trigger webhook-functionality in a workflow. I dont understand how to send JSON to Slack. The only thing that I have found that works is to write “Text” in the “Enter title”-field and a plain text message in the other field.

Are you trying to trigger a Slack webhook with this module? Then it’ll parse your blocks JSON and send a message?

I solved it! If you write `blocks` in the Enter title-field, you can enter a block like this in the Enter value-field:

```auto
[
		{
			"type": "section",
			"text": {
				"type": "plain_text",
				"text": "This is a plain text section block.",
				"emoji": true
			}
		}
	]

```

You should construct a JSON using Glide’s JSON columns and reference it on the right, if I get your idea right.
