• Completed lindy-install-auth setup

Instructions

3. Agent Builder auto-generates the workflow with trigger + action nodes

Step 2: Configure the Webhook Trigger

1. Click the trigger node at the top of the workflow canvas

2. Select Webhook Received

3. Copy the generated URL:

Step 3: Add the Slack Action

1. Click "+" to add a step
2. Search for Slack Send Channel Message
3. Authorize your Slack workspace when prompted
4. Configure fields:

   • Instruction:

     Payload: {{webhook_received.request.body}}
     

Step 4: Set the Agent Prompt

Open Settings > Prompt:

You are a webhook summarizer. When you receive a webhook payload,
extract the key information and create a concise one-sentence summary.
Be factual and specific. Do not add opinions or speculation.
