Smarter Webinar Lead Generation: How to Turn Signups into Actual Sales With an API

Picture the scene. 

You just ran a great – and we mean great – webinar. The guests were on point, the insights were genuinely useful, the viewers were engaging, and you think you might be up for an Oscar for your delivery. Amazing stuff. 

A couple of weeks go by and you’re still bathing in the afterglow. Until…hang on a minute…What happened to all those webinar leads? Anyone? Hello? 

Here’s the thing: webinar lead generation can bring in a ton of qualified prospects, but without the right follow-up, those leads can slip through the cracks. Most teams end up with just a name and email – not much to work with. That’s why pairing your webinar lead generation efforts with a contact enrichment API is a game changer. It fills in the missing details, helping you personalize outreach, score leads properly, and keep your pipeline flowing.

Sound good? Of course it does. Below we’ll walk you through exactly how to do it with the Surfe:

When You Should Use an API for Enriching Your Webinar Leads

So, you’ve run your webinar. Leads are in. Now comes the fun part: turning a basic attendee list into something you can actually use.

There are a couple of ways to do so:

• Upload the list directly to Surfe’s web app
• Enrich it via Surfe’s Contact Enrichment API

“But when should I use each one?!” we hear you cry. Don’t worry – coming right up: 

When to Just Use Surfe’s Web App

If your webinar’s wrapped up and you’ve already collected a static list of attendees – say, from your webinar platform – uploading a CSV into Surfe is the simplest move.

Here’s how it works:

• Export your attendee list
• Upload it to Surfe
• Enrich the data with verified contact info
• Sync the enriched leads directly to your CRM

Quick, no-code, and perfect for one-off webinars where speed matters but automation isn’t essential.

Tip:
If you’re working directly with leads on LinkedIn (like you ran a LinkedIn Live or promoted heavily there), it’s usually quicker to use Surfe’s LinkedIn integration instead — enrich automatically, and sync instantly to your CRM.

When You Should Be Using the API

If you’re looking to level up your webinar lead generation, this is where the API shines.

Using Surfe’s API gives you:

• Control over how and when enrichment happens
• The ability to enrich leads in real time
• Integration with your broader lead gen stack (CRM, booking tools, outreach platforms)

Let’s say you build a script that sends attendee info to Surfe’s API as soon as someone registers. Surfe enriches the data – using either a LinkedIn URL, or a combo like First Name + Last Name + Company Name or Website. Once enriched, the data gets pushed automatically to:

• Your CRM
• Your scheduling tool (like Chili Piper or Calendly)
• Your outreach platform

Now, every lead is enriched, qualified, and ready for contact – while you’re busy working on everything else. Seeya later, manual uploads, messy spreadsheets, and delays! 

Yes, it takes a bit of technical setup. But if you’ve got a dev team – or you’re multitalented and handy with scripts – it’s totally doable. Ask ChatGPT to write the code and you’ll be live in under an hour.

The Current (Broken) Flow

Most teams still follow an old-school flow:

• Export a CSV or pull leads from a webinar tool
• Leads include just names and maybe company names
• Reps are left to guess who’s who, or skip the research entirely
• Follow-up is slow, generic, and mostly ignored

That leads to:

• Low engagement
• High bounce or unsubscribe rates
• Missed sales opportunities

With Surfe’s API, webinar lead generation becomes what it should be: instant, actionable, and scalable. 

How Surfe’s Contact Enrichment API Fixes The Problem

Spoiler alert: you’re about to go from a raw attendee list to a qualified lead in minutes. Right now, your attendee list probably looks something like this:

• First name
• Last name
• Maybe a company name, if you’re reeeeally lucky

That’s not enough to follow up properly – or at all. Which is exactly why you need Surfe’s Contact Enrichment API to turn your list into full, sales-ready profiles. 

The New Webinar Lead Generation Flow

Here’s what it looks like:

Input:
You write a custom script that sends attendee data to Surfe’s API.

To run a search, all you need is a LinkedIn URL or a combination of: 

• First Name + Last Name + Company Name
• First Name + Last Name + Company Website
  

Surfe handles the rest, and returns to you with: 

• First name
• Last name
• Email
• Phone
• Company name
• Company website
• Country
• Department
• Job title
• Social profiles (LinkedIn, Meta, Twitter)
  

The result? Fully enriched contact profiles – in minutes. And for your team, this means leads ready to: 

• Sync with your CRM
• Slot into your marketing workflows
• Be picked up by your sales team without a hitch

Before you know it, you and your team will stop guessing who to reach out to, be able to segment leads by seniority, industry, or location, and launch personalized campaigns the day after your event.

This is webinar lead generation that actually does something. Love it.

Want to Go Further? Stack APIs and Build Your Ideal Workflow

So you’ve enriched your webinar leads with Surfe’s Contact Enrichment API – great. Now what?

The next step is totally up to you. Really! Once you’ve written a bit of code, that clean, structured, enriched list can plug directly into every part of your lead generation workflow.

Sure, APIs sound technical (and they are), but that doesn’t mean you need a whole engineering team to make it work. If you’re a solopreneur, a scrappy founder, or just someone who’s not afraid to get their hands a little bit dirty, you’re more than capable of pulling this off. Honestly, ask AI to write you the script and you could be live before your next coffee break.

Here’s what that might look like:

Step 1: Run the Enrichment Code

This is the bit where Surfe’s API does its thing: takes your webinar attendees and turns them into full lead profiles.

*Pssst!* Need help writing that script? We’ve got a full how-to blog coming soon – stay tuned.

Step 2: Push Enriched Leads to Your CRM

Once you’ve got your enriched leads, it’s time to put them to work.

This is all handled via APIs. For example, you could fully automate Surfe-Salesforce activity by getting Surfe API to work with the Salesforce API.

All you’d need to do is get the Surfe API to enrich your leads, then send them directly to Salesforce – no downloading, uploading, or “please wait while Excel crashes.”

Step 3: Sync to Your Outreach Platform

From your CRM, leads can flow straight into your sales engagement or email marketing platform – like Outreach, Salesloft, or HubSpot Sales.

For example, combine the Surfe API with the Outreach API, and you’ll be able to: 

• Personalize your follow-up emails using enriched data fields
• Segment leads by seniority, title, or company
• Trigger nurture campaigns or pass top leads to your sales team on day one

Once the pieces are in place, the entire process runs in the background – while you focus on closing deals or prepping your next webinar.

Want to Go Even Further? Build Smarter Workflows with Your Enriched Data

Enriching your webinar leads is a huge win. But it doesn’t have to stop there.

With Surfe’s Contact Enrichment API, you can connect your data to the rest of your stack and automate what happens next – from lead scoring to routing to alerts. Whether you’re running on no-code tools or a full internal system, the flexibility is all yours.

For example, link up the Surfe API + Zapier API, and you’ll enjoy automation on autopilot:

Webhooks: send enriched data in real-time to another tool in your stack – as soon as it’s ready. 

Zapier: use Zapier to create no-code automation between Surfe and tools like Slack, Google Sheets, email platforms, or CRMs. Set it up once, and let it run in the background.

Your Internal Data Pipeline: If your team already has internal systems in place, Surfe’s API can slot right in – enriching leads and pushing data wherever it’s needed across your sales or ops infrastructure.

Bonus: A Few Smart Things You Can Set Up

Real-time lead scoring
As soon as a lead is enriched, send the data to a scoring system. Rank leads by job title, company size, or seniority so your reps can focus on the highest-value prospects first.

Automatic routing to the right sales rep
Enriched leads can be assigned automatically based on region, industry, or account size. Easy peasy! 

Instant alerts for high-priority leads
If a lead from a target account signs up and gets enriched with a senior title, fire off a Slack or email alert to the assigned rep so they can jump on it fast.

You don’t need to build all of this to get value –  just enriching your attendee list is already a massive step forward. But if you’re ready to take it further, Surfe’s API gives you the power to build a lead workflow that’s actually yours.

Let’s Wrap It Up!

Hey – did we just find a real-life Oscar in the bin? 

Turns out, you don’t need external validation when your webinar lead generation is this good. With Surfe, it’s fast, easy, and actually helps you follow up with real context. Why wouldn’t you?! 

FAQs About Webinar Lead Generation 

What Is Webinar Lead Generation?

Webinar lead generation is the process of using webinars to attract potential customers and capture their contact information. It’s a favorite tactic in B2B sales because it combines education, real-time engagement, and intent. When someone signs up for your webinar, they’re telling you they’re interested in your topic – which often means they could be a great-fit lead. The challenge? Turning those signups into actual sales opportunities. That’s where tools like Surfe’s Contact Enrichment API come in: they help you turn a list of attendees into qualified, enriched leads you can actually follow up with. 

How Do You Turn Webinar Leads Into Sales?

Turning webinar leads into sales starts with proper follow-up – and that means knowing more than just a name and email. Most webinar lists are basic. To convert those leads, you need context: job title, company, LinkedIn profile, and more. Surfe’s Contact Enrichment API helps by transforming raw attendee data into complete lead profiles. From there, enriched leads can be pushed straight to your CRM, routed to the right rep, and dropped into personalized campaigns. Clever! 

Why Use an API for Webinar Lead Generation?

Surfe’s Contact Enrichment API connects your sign-up form to your CRM, booking tool, and outreach platform, turning every attendee into a sales-ready contact without you lifting a finger. It’s ideal for teams with existing workflows, but just as accessible for solo operators. If you want your webinar leads to go straight into your pipeline (and not sit in a spreadsheet), the API is the move.

What Can You Do With Enriched Webinar Leads?

Once you’ve enriched your webinar leads, the possibilities open up fast. You can segment by seniority, industry, or location, personalize every follow-up email, and hand high-value leads directly to sales. Want to go further?
