API Mastery Made Simple: Explore Apollo's Developer Hub

APIs are a double-edged sword.

On one hand, they are incredibly powerful, enabling you to connect a software’s functionality to your other tools and processes in ways that are meaningful and wholly integrated.

On the other hand? They can be incredibly difficult to understand.

Success is determined by the quality of documentation. 

This is why Apollo has launched a new and improved API Developer Hub — to better support the partners and customers that are building unique business solutions with Apollo’s powerful APIs. 

The Developer Hub features:

• Endpoint testing directly in the docs (API keys required)
• Clear, accurate language to describe the available parameters and general endpoint functionality
• Tutorials for common Apollo.io API use cases
• OAuth 2.0 implementation guidance for Apollo.io partners

It’s chock full of information — with several approachable articles with step-by-step tutorials for implementing your dream integrations and workflows.

Explore Apollo’s API Developer Hub for yourself.

Review of the basics: What’s an API?

APIs are an integral component of how the internet — and modern business — works.

Take your banking app, for example. What you see on your screen is just the front-end. Your bank doesn’t actually store your account balance or recent transactions on your phone. Instead, that information is kept on a server.

To create and display your unique information, the bank generates an API key linked to your account. Every time you log in, this API key is used to securely fetch your information from the bank's servers.

In the same way that a key opens a lock, this API “key” allows you to access and customize a software’s powerful features in a way that’s unique to you.

And “endpoint URLs” give that action a path. They provide the specific addresses where the API can access data or perform actions. When you use your API key to make a request, it directs the app to the correct endpoint, allowing it to retrieve the information you want it to.

Apollo’s Developer Hub makes it easy to create API keys and provides the endpoint URLs — with each one’s use case — to build powerful workflows for your go-to-market teams.

Put Apollo.io's public APIs to the test

To generate an API key and get started with testing, check out the Create API Keys article in the docs.

You can also test the endpoints in the docs by using an API key to authenticate your API requests and entering values for the parameters.

Keep in mind that your access to endpoints is potentially limited by your team's Apollo.io pricing plan and the scopes you apply to your API key.

With an API key in hand, head to the reference docs and start testing endpoints for data enrichment, contact and account creation, sequences, and more. 

And if you're not ready to test, no worries – you can review example responses (including schema) for every endpoint without testing.

To test an endpoint, you should:

1. Enter your API key in the Authorization Header field.
2. Choose one of the available programming languages.
3. Enter details in the parameters to generate your API request. At a minimum, address the required parameters. As you add values to the parameters, the API request will update live.
4. Click Try It! to send your request.

The response from the API appears directly in the docs.

Follow this, step-by-step, in Apollo’s API Developer Hub. It’s open and ready for you to test, use, and customize today.
