Automatically Send Trustpilot Review Invites When Zendrop Marks Orders as Delivered

When Zendrop marks an order as delivered, this workflow automatically sends a Trustpilot review invitation to the customer. Store owners get more reviews without any manual follow-up.

difficulty Intermediatesetup 45 minresult Every delivered Zendrop order triggers a Trustpilot review invitation email sent automatically to the customer.—
  1. 1

    Step 1 — Receive Zendrop Delivered Webhook

    Add a Webhook node as the trigger. Set the HTTP method to POST. Copy the generated webhook URL and paste it into your Zendrop account under Settings > Webhooks. Choose the order.delivered or equivalent delivery status event. This node will fire every time an order is marked delivered.

  2. 2

    Step 2 — Extract Customer and Order Data

    Add a Set node after the webhook. Create fields to hold the key values from the incoming payload: set customerEmail to {{ $json.body.customer.email }}, customerName to {{ $json.body.customer.name }}, and orderReference to {{ $json.body.order.id }}. Adjust the expression paths to match the exact field names Zendrop sends in its webhook payload.

  3. 3

    Step 3 — Check That Email Exists

    Add an IF node to make sure the customer email is not empty before calling Trustpilot. Set the condition: {{ $json.customerEmail }} is not empty. Connect the true branch to the next step and leave the false branch unconnected (or connect to a Stop node) to avoid sending broken invitations.

  4. 4

    Step 4 — Send Trustpilot Review Invitation

    Add an HTTP Request node. Set Method to POST and URL to https://invitations-api.trustpilot.com/v1/private/business-units/YOUR_BUSINESS_UNIT_ID/email-invitations. Under Authentication choose Header Auth and add your Trustpilot API key as apikey in the header. Set Body Type to JSON and paste the body: { "consumerEmail": "{{ $json.customerEmail }}", "consumerName": "{{ $json.customerName }}", "referenceId": "{{ $json.orderReference }}", "locale": "en-US", "senderEmail": "reviews@yourdomain.com", "senderName": "Your Store Name", "templateId": "YOUR_TEMPLATE_ID" }. Replace placeholders with your real Trustpilot Business Unit ID, template ID, and sender details. Store your API key in an n8n credential.

  5. 5

    Step 5 — Log the Result

    Add a final Set node to capture the Trustpilot API response. Set a field invitationStatus to {{ $json.status }} and invitationId to {{ $json.id }}. You can connect this to a Google Sheets or Airtable node later to build an audit log of all invitations sent.

Frequently asked questions

How do I find my Trustpilot Business Unit ID?

Log in to your Trustpilot Business account, go to Integrations > API, and your Business Unit ID is displayed there. It is a long alphanumeric string and must be included in the API URL.

What Zendrop plan do I need for webhooks?

Zendrop's webhook functionality is available on their Plus or Pro plans. Check your current plan under Settings in the Zendrop dashboard and upgrade if the Webhooks option is not visible.

Will customers receive duplicate invitations if the order status updates multiple times?

Trustpilot's API deduplicates invitations by `referenceId` within a set window, but to be safe you should use the order ID as the referenceId and consider adding a check against a log (e.g., Google Sheets) before calling the API to confirm the invitation has not already been sent.
