Stop Chasing Signatures Manually
If you've ever sent a contract, waited three days for a reply, sent a follow-up email, and then manually filed the signed PDF — you already know the pain. Document signing is one of those tasks that looks simple but quietly eats hours every week. The good news? You can build a fully automated document signing workflow in about 30 minutes, using tools that require zero coding knowledge.
In this guide, you'll learn how to connect airslate with n8n to create an end-to-end automation: from triggering a document request to collecting a signature and storing the final file — all without lifting a finger after setup.
What You'll Build
Here's the complete flow you'll have running by the end of this tutorial:
- A trigger event (new row in a spreadsheet, form submission, or CRM update) fires in n8n
- n8n sends the signer's data to airslate
- airslate generates a pre-filled document and sends it to the recipient for e-signature
- Once signed, airslate notifies n8n via webhook
- n8n saves the signed PDF to Google Drive and logs the completion in your spreadsheet
The entire process runs without any manual intervention after the initial setup.
Tools You'll Need
- airslate — handles document generation, e-signature requests, and completion tracking
- n8n — acts as the automation backbone, connecting your data sources and orchestrating the workflow
- Google Sheets (or any CRM/form tool as your trigger source)
- Google Drive (for storing signed documents)
Step 1: Set Up Your Document Template in airSlate
Start inside airslate. Create a new Flow and upload your contract or agreement as a PDF or Word document. Use airslate's drag-and-drop field editor to add signature fields, date fields, and any auto-fill placeholders — for example, {{signer_name}} or {{company}}.
Once your template is ready, go to the Integrations tab inside airslate and enable the Webhook option. Copy the webhook URL — you'll need this in n8n. Also note your airslate API key from the account settings.
Step 2: Build the Trigger in n8n
Open n8n and create a new workflow. Add a Google Sheets Trigger node (or use a Webhook node if your trigger comes from a form or CRM). Configure it to fire whenever a new row is added — for instance, when a new client is onboarded.
Map the relevant fields from the sheet: name, email address, company, and any other variables your document template uses. This data will be passed directly to airslate in the next step.
Step 3: Connect n8n to airSlate
In n8n, add an HTTP Request node after the trigger. Configure it as follows:
- Method: POST
- URL: The airslate API endpoint for creating a new flow instance
- Authentication: Add your airslate API key as a Bearer token
- Body: Pass the signer's name, email, and any template variables as JSON
When n8n executes this request, airslate automatically generates a personalised document and dispatches it to the signer's email address — complete with a secure signing link.
Step 4: Handle the Completion Webhook
Back in n8n, add a Webhook node and paste in its URL inside airslate's completion webhook settings. Now whenever a document is signed inside airslate, it will ping n8n instantly.
After the webhook node in n8n, chain the following actions:
- An HTTP Request node to download the signed PDF from airslate
- A Google Drive node to upload and store the file in the correct folder
- A Google Sheets node to update the row with a "Signed" status and timestamp
Step 5: Test and Activate
Run a test execution inside n8n using a sample row. Check that airslate receives the data correctly, sends the signing email, and triggers the completion webhook after you sign the test document. Once everything passes, activate your n8n workflow — it will now run continuously in the background.
Pro Tips to Extend This Workflow
Add Automated Reminders
Use a Schedule Trigger in n8n to check for unsigned documents daily and resend reminder emails automatically — no more manual chasing.
Multi-Party Signing
airslate supports sequential and parallel signing. Simply configure multiple signer roles inside your airslate template and pass each signer's data via n8n.
Slack or Email Notifications
Add a Slack or Gmail node in n8n right after the completion webhook to notify your team the moment a contract is signed. Fast, clean, zero email archaeology.
Why This Combination Works So Well
airslate handles the legal and UX complexity of e-signatures — audit trails, tamper-proof records, compliance-ready outputs. n8n handles the data orchestration — moving information between your tools without glue code. Together, they form a production-ready document automation stack that would cost a developer days to build from scratch.
The 30-minute investment today means every future contract goes out and comes back on autopilot. That's not just a time saving — it's a process that scales with your business without adding headcount.
Ready to Build It?
Start by setting up your free airslate account and spinning up n8n (self-hosted or cloud). Follow the steps above, test with a real document, and activate. Your signing process will never be the same again.
