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.

The table below shows which endpoints are currently implemented:

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 three separate credentials:

Resend OAuth2 API (recommended)

1. In n8n, go to Credentials > Add credential and search for Resend OAuth2 API
2. Click Connect my account

That’s it! n8n registers itself as an OAuth client with Resend.

> [!NOTE]
> Dynamic Client Registration relies on OAuth2 support that’s new in n8n core. If Connect my account doesn’t work, make sure you’re on a recent n8n version, or use the Resend API credential below instead.

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 when Authentication is set to API Key.

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

Configuration Options

| Option | Description |
| ———————— | ——————————————————– |
| Response Type | Choose between Approval (buttons) or Free Text (form) |
| Approval Type | Single button (Approve only) or Double (Approve/Decline) |
| Button Labels | Customize the button text |
| Button Styles | Primary or Secondary styling |
| Message Button Label | Label for the form link button (Free Text mode) |
| Response Form Title | Title shown on the response form |
| Limit Wait Time | Set a timeout for the wait period |

Trigger Events

The Resend Trigger node receives webhooks for real-time email events. Signatures are automatically verified using Svix.

> [!NOTE]
> The trigger node requires the Resend Webhook Signing Secret credential (separate from the Resend API credential). See the Credentials section for setup instructions.

For a full list of supported event types, see the Resend Webhooks documentation.

Limitations

• Maximum email size: 40MB (including attachments)
• Attachments not supported with scheduled emails
