This article provides a complete, practical walkthrough of the Http Stickynote Create Webhook n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   In today’s fast-paced digital sales environment, automating lead generation and CRM updates can drastically improve efficiency and sales pipeline visibility. This n8n-powered workflow showcases how to integrate multiple services—Tally Forms, CaptainVerify, SuiteCRM, Nextcloud, and Brevo—to streamline lead intake, email validation, and data synchronization.
   
   Let’s take a closer look at how this no-code/low-code solution works and how it accelerates your lead registration workflow without any manual data entry or validation.
   
   
   1. Triggering the Workflow via Form Submissions
   
   The user journey starts with a Tally Form submission, where user data like name and email is collected. The trigger node in the workflow—named “Tally Forms Trigger”—initiates the process. The form data is passed along to subsequent steps for validation and processing. Thanks to n8n’s adaptability, you can replace this trigger with other form tools (like Typeform, Google Forms, etc.) if needed.
   
   
   2. Seamless Email Validation with CaptainVerify
   
   The next step in the chain leverages CaptainVerify, a trusted email verification service. Here, the workflow checks the format and deliverability risk of the submitted email address using an API call:
   
   https://api.captainverify.com/v2/verify?apikey=YOURAPIKEY&email={{ formEmail }}
   
   With this validation step, businesses can prevent spam or invalid addresses from entering their CRM or mailing list systems. This is crucial to reduce email campaign bounce rates and protect sender reputation.
   
   
   3. Low Credit Alert for Email Validation
   
   Before proceeding with email validation results, the workflow checks if there are enough credits available on your CaptainVerify account. If the remaining credits drop below 100, the system makes a POST request to your Nextcloud Talk (Spreed) instance, notifying your team of the low-credit situation.
   
   This alert ensures transparency and provides an early warning to team members so they can top up the service before it hinders data processing.
   
   
   4. Handling Invalid Email Submissions
   
   Next, the workflow evaluates the outcome of the CaptainVerify response. If the email is flagged as invalid, the workflow halts further processing and sends a message to a specified Nextcloud Talk group. The alert contains both the contact’s name and submitted email, helping the team follow up if necessary.
   
   This step preserves CRM integrity by keeping invalid data out and gives visibility into form submission errors in real-time.
   
   Example notification:
   "Invalid mail on submission form for contact: John Doe and mail: johndoe@example.com"
   
   
   5. SuiteCRM Integration: Authenticating and Creating Leads
   
   If the email passes validation, the workflow proceeds to acquire an OAuth access token from SuiteCRM. It uses client credentials to authenticate via SuiteCRM’s V8 API. This step is mandatory before making changes to the CRM.
   
   After acquiring the token, the workflow proceeds to create a new lead record inside SuiteCRM using the user-submitted data.
   
   The lead is populated with attributes like:
   - Last name
   - Email
   - Lead status (“Hot”)
   - Source (“FormsChoice”)
   - Assigned user
   - Description about the form submission context
   
   
   6. Syncing Data with Brevo for Email Marketing
   
   Once the lead is created in SuiteCRM, the next step is to send the contact data into Brevo (formerly known as Sendinblue). This integration creates or updates a contact and includes a reference to the newly created SuiteCRM lead by storing the Lead ID in a custom attribute.
   
   This allows your marketing efforts to remain tightly aligned with the customer journey by bridging CRM ID data into Brevo.
   
   
   7. Real-Time Team Notification: Lead Successfully Created
   
   Finally, upon successful creation of records in both SuiteCRM and Brevo, the workflow pushes one more message to the appropriate Nextcloud Talk discussion group.
   
   This message informs the team that a new lead has been added, including the contact’s name and email address. Such notifications create transparency in cross-departmental workflows and motivate quick action from sales reps, who can follow up while the lead is still warm.
   
   
   Benefits of the Workflow
   
   - Prevents junk data from cluttering CRM
   - Saves manual time and reduces error-prone tasks
   - Aligns marketing and sales data between Brevo and SuiteCRM
   - Notifies team members in real-time using Nextcloud Talk
   - Offers visibility into email validation credits
   
   By integrating these third-party tools into a single n8n workflow, you gain a powerful automated system that handles data intake, real-time alerts, and CRM syncing with precision.
   
   
   Third-Party APIs Used in the Workflow:
   
   1. CaptainVerify – Email address verification API  
   2. SuiteCRM V8 API – For token authentication and lead creation  
   3. Nextcloud Talk (Spreed) API – For sending chat notifications to discussions  
   4. Brevo (formerly Sendinblue) API – For contact creation in an email marketing platform  
   
   Conclusion
   
   With n8n at the center of your automation ecosystem, you can build robust and scalable workflows that bridge the gap between multiple platforms without writing extensive code. This workflow is an excellent example of how businesses can harness automation to streamline form-based lead capture and ensure only high-quality data enters their systems. Whether you’re working in marketing, sales, or IT, automating your contact management and validation pipeline has never been easier.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
