What You’ll Build

A simple n8n workflow that captures form submissions and stores them in Alchemyst so you can search them later.

​
What You Need

  • An Alchemyst API key from your dashboard
  • Basic familiarity with n8n

​
Step 1: Create a Webhook

  1. In n8n, create a new workflow
  2. Add a Webhook node
  3. Copy the test URL
  4. Send a test request with this JSON:
{
  "name": "John Doe",
  "email": "[email protected]",
  "message": "Hello, I need help with my account"
}

​
Step 2: Add HTTP Request Node

  1. Add an HTTP Request node after the webhook
  2. Set these values:
    • Method: POST
    • URL: https://platform-backend.getalchemystai.com/api/v1/context/add
  3. Under Authentication, select Generic Credential Type → Bearer Token
  4. Create a new credential and paste your Alchemyst API key
  5. Set Body Content Type to JSON
  6. Set Specify Body to JSON
  7. In the JSON field, paste this expression:
{{ JSON.stringify({
  documents: [
    {
      content: $json.body?.message ?? $json.message ?? "",
      containerTag: "contact-forms",
      metadata: {
        name: $json.body?.name ?? $json.name ?? "",
        email: $json.body?.email ?? $json.email ?? ""
      }
    }
  ],
  source: `contact-form-${DateTime.now().toMillis()}`,
  context_type: "resource",
  scope: "internal",
  metadata: {
    fileName: `contact_form_${DateTime.now().toMillis()}.json`,
    fileType: "contact/form",
    fileSize: (($json.body?.message ?? $json.message ?? "").length) * 8,
    lastModified: $now.toISO()
  }
}) }}

​
Step 3: Test It

  1. Click Execute Workflow
  2. You should see a success response
  3. Go to your Alchemyst dashboard to verify the data was saved

​
Congratulations! 🎉

You’ve successfully built your first Alchemyst workflow in n8n! Your workflow is now capturing form submissions and storing them as searchable context in Alchemyst.

​
Complete Workflow for Reference

Here’s the complete workflow you just built. You can import this directly into n8n: To use: Copy the JSON below → In n8n, go to Workflows → Import from URL or File → Paste and import → Add your Alchemyst API key to the credential.
