Why automate Seven with n8n?
The seven n8n integration gives you access to 2 powerful actions for automating SMS and voice communications directly within your workflows. Instead of manually sending messages or making calls, you can set up intelligent rules that trigger communications automatically based on events from any of your connected applications.
Significant time savings: No more copying phone numbers and typing messages manually. Configure your SMS or voice call parameters once, and let n8n handle the execution every time a trigger fires—whether that's a new form submission, a CRM event, or a scheduled task. Improved responsiveness: React instantly to critical events. When a high-priority lead comes in, send an immediate SMS. When a server alert fires, trigger a voice call to your on-call team. The delay between event and action drops from hours to seconds. Seamless integration: Connect seven to over 400 applications in n8n's ecosystem—CRMs like HubSpot or Salesforce, e-commerce platforms like Shopify, databases like Airtable, and custom webhooks from any system.
Concrete workflow examples:
- Automatically send SMS order confirmations when a new sale is recorded in your e-commerce platform
- Trigger voice calls to your support team when a critical ticket is escalated
- Send appointment reminder SMS 24 hours before scheduled meetings from your calendar
- Notify customers via voice call when their delivery is out for shipping

Search and add the node in your workflow.
TIP💡 TIP: Keep your API key secure and never share it publicly. If you suspect your key has been compromised, regenerate it immediately in your seven.io dashboard. Also, consider setting up a dedicated API key specifically for n8n automations—this makes it easier to track usage and revoke access if needed without affecting other integrations. For more best practices, check the official n8n credentials documentation.- 01

Seven actions available in n8n
01 Action 01Send SMS
The Send SMS action allows you to programmatically send text messages to one or multiple recipients directly from your n8n workflow. This is the core action for any SMS-based communication automation, whether you're sending transactional messages, notifications, or marketing communications.
Key parameters:
- Credential to connect with: A required dropdown field where you select your pre-configured seven account containing your API key for authentication.
- Resource: A required dropdown set to "SMS" to indicate you're working with text messaging functionality.
- Operation: A required dropdown set to "Send" to specify that you want to dispatch an SMS message.
- From: A required text field where you specify the sender's phone number or alphanumeric sender ID (e.g., "+4901234567890" or "MyCompany"). This is what recipients will see as the message source.
- To: A required text field accepting comma-separated phone numbers and/or group names (e.g., "+49876543210, MyGroup"). This allows you to send to multiple recipients in a single action.
- Message: A required multi-line text field where you compose your SMS content. You can use n8n expressions to dynamically insert data from previous nodes.
- Options: An expandable section for additional configurations like delivery reports, message type, or flash SMS settings.
Practical use cases:
- Send order confirmation SMS when a new purchase is completed in Shopify or WooCommerce
- Dispatch appointment reminders by connecting to Google Calendar or Calendly
- Alert team members when a critical form submission arrives via webhook
- Send two-factor authentication codes triggered by user login events
02 Action 02Voice Call
The Voice Call action enables you to initiate automated voice calls that play a pre-recorded or text-to-speech message to recipients. This is particularly valuable for urgent notifications, verification calls, or any scenario where a phone call is more impactful than a text message.
Key parameters:
- Credential to connect with: A required dropdown to select your authenticated seven account for API access.
- Resource: A required dropdown set to "Voice Call" indicating the action will handle voice communication rather than SMS.
- Operation: A required dropdown set to "Send" to specify that you're initiating an outbound voice call.
- To: A required text field where you enter the recipient phone number(s) or group names, comma-separated (e.g., "+49876543210, MyGroup"). The system will call each number sequentially or simultaneously based on your seven.io account settings.
- Message: A text field containing the audio message content to be played during the call. This text is converted to speech using seven.io's text-to-speech engine.
- Options: An expandable section for additional call parameters such as voice selection, language settings, or callback URLs for call status updates.
Practical use cases:
- Trigger urgent voice alerts when server monitoring detects critical issues
- Send voice verification codes for high-security authentication flows
- Notify on-call staff when high-priority support tickets are created in Zendesk
- Deliver important announcements that require immediate attention beyond what SMS provides

Frequently asked questions
Is the seven n8n integration free?
The n8n integration itself is completely free to use—both on n8n cloud and the self-hosted open-source version. However, you'll need an active seven.io account, and sending SMS or voice calls incurs costs based on seven.io's pricing structure. These costs depend on the destination country, message length, and call duration. We recommend checking seven.io's current pricing page for accurate rates and considering their prepaid credit system or monthly plans based on your expected volume.What phone number formats does the seven n8n integration accept?
The seven integration accepts international phone numbers in E.164 format, which includes the country code with a plus sign (e.g., "+33612345678" for France or "+14155551234" for the US). You can also use group names that you've pre-configured in your seven.io dashboard for sending to multiple contacts at once. When specifying multiple recipients, separate them with commas. Avoid using spaces or special characters other than the plus sign and digits in phone numbers.How long does it take to set up the seven n8n integration?
Setting up the seven n8n integration typically takes 5-10 minutes if you already have a seven.io account with credits. The process involves copying your API key from seven.io, pasting it into n8n's credential manager, and configuring your first Send SMS or Voice Call action. If you're creating a seven.io account from scratch, add another 5-10 minutes for account verification and adding initial credits. Once configured, creating new workflows using seven becomes nearly instant since credentials are saved and reusable. If you encounter issues, check our n8n troubleshooting guide for common solutions.
