The official node for n8n that integrates with the Resend API. Send emails, manage contacts, handle domains, and receive webhooks.

API Coverage

[!WARNING] Audiences are deprecated in favor of Segments and won't be supported in this node. Please use Segments for contact grouping and targeting.

Installation

1. Make a new workflow or open an existing one
2. Open the nodes panel by selecting + or pressing Tab
3. Search for Resend
4. Select Install to install the node for your instance

Credentials

This package uses two separate credentials:

Resend API

1. Get your API key from Resend Dashboard
2. In n8n, go to Credentials > Add credential
3. Search for Resend API and paste your key

This credential is used by the main Resend node for all API operations.

Resend Webhook Signing Secret

1. Create a webhook endpoint in your Resend Dashboard
2. Copy the signing secret (starts with whsec_)
3. In n8n, go to Credentials > Add credential
4. Search for Resend Webhook Signing Secret and paste your secret

This credential is used exclusively by the Resend Trigger node for webhook signature verification. Each webhook endpoint in Resend has its own unique signing secret.

Human in the Loop

The Send and Wait for Response operation enables human-in-the-loop workflows. Send an email and pause the workflow until the recipient responds via approval buttons or a form.

Features

• Approval Workflows: Send emails with Approve/Decline buttons for quick decisions
• Free Text Responses: Collect text input via a response form
• Configurable Wait Time: Set a timeout or wait indefinitely
• Secure Callbacks: Responses use signed URLs for security

How to Use

The workflow pauses at the email step and resumes automatically once the recipient clicks a button or submits the response form.

1. In the node panel, go to Human in the Loop > Resend
2. Or select Email resource > Send and Wait for Response operation
