Turn form submissions into real-time Slack pings so your sales team can respond to leads within minutes — not hours.
Before you start: make sure you have a Slack workspace where you can install an app (or ask an admin), and a form on your Hiveku project that you can wire a webhook to.

​
The Flow at a Glance

1. Slack webhook

Create an incoming webhook URL in Slack

2. Hiveku workflow

Webhook trigger + HTTP action

3. Form wiring

Point the form’s submit to the trigger URL

​
Step 1: Create an Incoming Webhook in Slack

1

Create a new Slack app

Go to api.slack.com/apps and click Create New App > From scratch. Give it a name (like Hiveku Leads) and pick the workspace you want it installed in.
2

Enable incoming webhooks

In the left sidebar, click Incoming Webhooks and toggle Activate Incoming Webhooks to On.
3

Add a webhook to your workspace

Scroll down and click Add New Webhook to Workspace. Pick the target channel (e.g., #leads) and click Allow.
4

Copy the webhook URL

Slack shows a URL like https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX. Copy this — you’ll paste it into Hiveku.
Treat the webhook URL like a password — anyone with it can post into your channel. Don’t commit it to git. Store it as a secret in your workflow.

​
Step 2: Create the Hiveku Workflow

1

Open Workflows

In your Hiveku project, go to Workflows > New Workflow. Name it Form Submission → Slack.
2

Add a Webhook trigger

Click Add Trigger and choose Webhook. Hiveku generates a unique webhook URL — copy it, you’ll wire your form to it in the next step.
3

Add an HTTP Request action

Click + Add Action > HTTP Request. Configure it:
  • Method: POST
  • URL: paste your Slack webhook URL
  • Headers: Content-Type: application/json
  • Body:
{
  "text": "New form submission from {{trigger.name}} ({{trigger.email}}): {{trigger.message}}"
}
4

Save and enable

Click Save, then toggle Enabled in the top right. Until this toggle is on, the workflow won’t fire.
Already have a lead pipeline in mind? From Workflows > New, pick the Form Lead → CRM + Notifications template — it ships with this Slack step plus a CRM contact action wired up.

​
Step 3: Wire Your Form to the Trigger

How you point your form at the trigger URL depends on how your form is built. See the Workflows overview for the full list of options.
Open the form in the content editor, scroll to Submission Settings, and paste the trigger URL into POST to webhook.

​
Referencing Form Fields

Inside the HTTP Request body, use {{trigger.fieldName}} to pull values from the submission. If your form POSTs { "name": "Ada", "email": "ada@example.com", "message": "hi" }, then {{trigger.name}} renders as Ada. Fallbacks use the || operator: 
{
  "text": "Lead from {{trigger.name || 'Anonymous'}} — source: {{trigger.source || 'website'}}"
}

​
Richer Slack Formatting

Plain text works fine, but if you want buttons, dividers, or multi-field layouts, use Slack’s Block Kit: 
{
  "blocks": [
    {
      "type": "section",
      "text": { "type": "mrkdwn", "text": "*New lead:* {{trigger.name}}" }
    },
    {
      "type": "section",
      "fields": [
        { "type": "mrkdwn", "text": "*Email:*\n{{trigger.email}}" },
        { "type": "mrkdwn", "text": "*Source:*\n{{trigger.source}}" }
      ]
    }
  ]
}
Use Slack’s Block Kit Builder to design visually, then paste the JSON into your HTTP action body.

​
Test It

1

Submit a test form

Open your site, fill out the form with test data, and submit.
2

Check Slack

You should see a message in the target channel within a few seconds.
3

Check the workflow run log

Workflows > your workflow > Runs tab shows each invocation, the payload received, and the HTTP response from Slack. Useful when nothing shows up.

​
Troubleshooting

Three common causes: (1) the workflow isn’t enabled — toggle it on; (2) the Slack webhook URL is wrong or deleted in Slack — regenerate it in api.slack.com/apps > your app > Incoming Webhooks; (3) the trigger never fired — check the workflow’s Runs tab, and verify your form is POSTing to the correct trigger URL.
Slack returns invalid_payload when the JSON is malformed. Quotes and newlines inside form values need escaping. Wrap user-submitted text in the template with safe substitution, or use Block Kit sections which are more forgiving.
Slack webhooks are rate-limited to roughly 1 message per second per webhook. If you’re seeing bursts (e.g., after an ad campaign), add a queueing step or batch submissions into a single message every minute.
Each Slack incoming webhook is bound to a single channel at creation time. To post to a different channel, create another webhook in Slack (Incoming Webhooks > Add New Webhook to Workspace) and update the URL in your HTTP action.
Add a Conditional step before the HTTP action that branches on {{trigger.form_name}} or similar. One branch posts to #sales, another to #support.
