In today's competitive business landscape, effective lead generation is critical for sustainable growth. Traditional cold outreach often underperforms due to its generic, one-size-fits-all approach. What if you could transform your prospecting into a personalized, data-driven system that delivers tailored messages to each potential client?
This guide explores how to integrate Apollo.io's robust APIs with Nocodo AI's no-code automation platform to build a sophisticated lead generation workflow. By combining Apollo.io's comprehensive contact data with Nocodo AI's powerful automation capabilities, you'll create a system that not only identifies promising leads but crafts customized outreach messages based on each prospect's specific profile and history.

What You'll Learn

  • How to access and configure Apollo.io's API for strategic lead generation
  • How to integrate Apollo.io's Search People and Enrich People APIs with Nocodo AI
  • How to build an automated workflow that identifies and enriches lead data
  • How to leverage Large Language Models (LLMs) to generate personalized outreach messages
  • Best practices for elevating your cold email conversion rates
Let's dive in!

Understanding Apollo.io: A Quick Overview

Apollo.io serves as a powerful B2B sales intelligence and engagement platform, providing access to over 265 million contact profiles. While its API offers numerous endpoints, we'll focus on two particularly valuable ones:
  1. Search People API : Enables you to discover potential leads based on targeted criteria such as job title, company size, industry, and more.
  2. Enrich People API : Transforms minimal contact information (like name and company) into comprehensive profiles including email addresses, phone numbers, social media accounts, and detailed company information.
These APIs deliver exceptional results when paired with Nocodo AI, which can process this rich data and trigger actions through predefined workflows.

What is Nocodo AI?

Before proceeding, let's understand what makes Nocodo AI special. Nocodo AI is a no-code workflow automation platform that enables users to build sophisticated automation sequences through an intuitive drag-and-drop interface. It seamlessly integrates with various services and AI models, making it possible to automate complex tasks without extensive coding knowledge.
With Nocodo AI, you can:
  • Create powerful multi-step workflows without writing a single line of code
  • Process diverse data formats (text, images, audio, video)
  • Connect with external APIs and AI models
  • Monitor and manage workflows through a comprehensive dashboard
Now, let's explore how Apollo.io's data capabilities and Nocodo AI's automation power can work together.

Getting Started with Apollo.io API

Creating Your Apollo.io API Key

Before building our workflow in Nocodo AI, we need to set up an Apollo.io account and generate an API key:
  1. Sign up for Apollo.io : If you don't already have an account, sign up for Apollo.io . Their free tier provides limited API access—perfect for getting started.
  2. Create an API Key :
    • Log in to your Apollo.io account
    • Navigate to Settings > Integrations
    • Find the API option and click Connect
    • Click on "API keys" and then "Create new key"
  3. Configure your API Key :
    • Give your key a descriptive name (e.g., "Nocodo Lead Generation")
    • Add a description for future reference
    • Select the specific API endpoints you need (for this tutorial, ensure "People Search" and "People Enrich" are selected)
    • For access to all available endpoints, toggle "Set as master key"
    • Click "Create API Key"
  4. Copy and Securely Store Your API Key : This key will authenticate your requests from Nocodo AI to Apollo.io.

Understanding Apollo.io API Rate Limits

Apollo.io enforces rate limits on API usage based on your subscription plan. Before building complex workflows, familiarize yourself with these limits:
  • Free tier : Limited daily API calls (typically sufficient for testing)
  • Paid plans : Higher limits based on subscription level
You can monitor your current limits and usage in the Apollo.io developer dashboard under "Plan overview".

Building Your Lead Generation Workflow in Nocodo AI

With access to Apollo.io's API secured, let's build a workflow in Nocodo AI that will:
  1. Search for potential leads based on specific criteria
  2. Enrich those leads with additional information
  3. Generate personalized outreach messages based on the enriched data

Step 1: Setting Up the Project in Nocodo AI

  1. Log in to your Nocodo AI account or sign up if you don't have one.
  2. Create a new project with a meaningful name, such as "Apollo Lead Generation".
  3. You'll access Nocodo AI's drag-and-drop interface where you can start building your workflow.
  4. In the "Settings" page create new "Generic API Key" Credential with your newly created Apollo.io API key.

Step 2: Configuring the Apollo.io API Connection

First, we need to establish the connection to Apollo.io in Nocodo AI:
  1. From the node library, drag the "Apollo.io" node onto the canvas.
  2. Configure the node with the following settings:
    • Credentials : Select the Credential you created in Step 1.
    • API Type : Search People
    • Additional: Add search criteria for all search details that are relevant for you.

Step 3: Processing the Search Results

Once we receive search results, we need to process them effectively:
  1. Add a "Data Conversion" node and connect it to the output of the "Apollo.io" node.
  2. Use the output directly as the input for a LLM node or add an additional "Text Input" node to provide more context for the llm

Step 4: Enriching Lead Data

For a potential lead identified, we'll use the Enrich People API to gather more detailed information, especially the email information, because the Search API does not return the email contact information:
  1. Add another "Apollo.io" node.
  2. Configure it with the following settings:
    • Credentials : Select the Credential you created in Step 1.
    • API Type : Enrich People
    • Additional: Add search criteria for all search details that are relevant for you.
  3. Add additional "JSON Query" to select the specific details from the user, e.g. First Name, Last Name, and Person Id.
  4. The results from the request you can use again as input for an LLM directly or add a "Text Input" node again to add some more instructions for the LLM.

Step 5: Generating Personalized Outreach Messages with LLMs

Now comes the truly powerful element—using Nocodo AI's LLM integration to craft personalized outreach messages based on the enriched data.
The workflow orchestrates your prospect data through Apollo.io and transforms it into targeted, personalized outreach that resonates with each individual recipient—elevating your response.
