What is API integration? And why is it important?

When data can’t move freely between your apps, harmful business consequences emerge. 

Employees will have to navigate between apps just to find the data they’re looking for; they’ll have to perform double data entry constantly; and they’ll have to give up valuable time in performing business-critical tasks. 

You can address these issues head on by investing in API (application programming interface) integration. How does it help? We’ll explain, but let’s start by aligning on what the term means.

What is API integration?

API integration is simply the connection of software applications through their application programming interfaces (APIs*). Once connected, these applications can request and share data between one another seamlessly, effectively eliminating any data silo at your organization.

For example, say you use Salesforce as your CRM and Marketo as your marketing automation platform. Using API data integration, you can connect the systems and allow key information to flow between them. Has a sales rep updated a prospect’s status in Salesforce? Those edits can instantly be reflected in Marketo; did a prospect’s lead score change after a Marketo campaign? The corresponding Salesforce account can automatically use the new score—and so on. 

This API integration example is just the tip of the iceberg, as you can apply it to any combination of apps in your ecosystem.

Why is API integration important?

With this definition in mind, here are just 3 ways that API integration can make a positive impact on your business:

It saves employees time

Now that your employees can avoid moving between apps to find the data they need, they’ll save a significant amount of time that they can reallocate towards other, more important, tasks.

Your marketers can spend more time on creating content assets for a given campaign; your sales reps can focus more on building out presentations for key prospects; your colleagues in finance can ideate strategies for improving their compliance and risk management; your employees in HR can hold more important conversations with employees, etc.

It prevents human errors

No individual is immune to mistakes. If they’re tasked with updating several applications themselves, they’re bound to make errors that lead to big issues down the line. 

For instance, if someone working in Salesforce gives a prospect a higher lead score than what’s shown in Marketo (i.e. the source of truth), a sales rep can be misled into thinking that a prospect is more sales-ready than they really are. This can lead the rep to nurture that prospect in a way that comes off as aggressive—ultimately dissuading the prospect from engaging with your brand any further.

API integration lessens the number of manual tasks your employees perform, thereby lowering the chances of incidents like the one above from taking place.

It improves the employee and customer experience

With employees able to spend more of their time on tactical, thoughtful tasks, versus manual, repetitive ones, they’re more likely to enjoy their work and be more productive. This also benefits customers as, according to the Harvard Business Review, happier employees are more likely to deliver experiences that leave customers happier as well.

It helps you get the most out of your apps

Once your apps include additional data via API integrations, the utility they provide to users only amplifies. Here are just a few examples:

  • You CRM platform can provide a 360-degree view on prospects and clients, empowering sales reps and colleagues in customer-facing roles to manage these key relationships more intelligently
  • Your applicant tracking system can retrieve offer letters sent to candidates and their respective completion statuses, helping recruiters track target candidates and follow up when necessary
  • Your ERP system can display accurate order information and generate invoices instantly, helping your finance team manage vendors effectively
  • Your marketing automation tool can access clients’ product usage data, enabling your marketers to nurture upsell and cross-sell opportunities successfully

It can enhance the product your organization offers

Many popular apps rely on API integrations to deliver value for end-users. You can point to various real-world examples for proof. 

This can be anything from a travel site like Expedia, which uses the APIs of various 3rd-party sites to help its searchers find the best deals on flights, hotel stays, car rentals, etc. to a payment service like Venmo—which uses the APIs of several banking institutions to let users transfer money over to their accounts.

Though your product’s API use cases may not be as obvious as the examples above, you’ll likely identify several opportunities that can improve your end users’ experience.

How to build an API integration

Once you’ve decided to integrate your apps via their APIs, the next question is how you want to go about doing it. You have a few options to choose from, with each offering a unique set of pros and cons:

1. Native API integration: When you use an app’s pre-built integration with another app.

Pros

  • Often provided at a low cost with your subscription
  • Normally supported by the organization that provides them
  • Can cover a variety of use cases across popular apps

Cons

  • Your organization likely has specific integration requirements that aren’t met by the native integration
  • The organization’s engineers have competing priorities, which can prevent them from focusing their time and effort on enhancing and fixing their native API integrations
  • It can’t deliver real digital transformation as building integrations doesn’t dramatically change your organization’s core workflows

2. In-house API integration: When your team builds the API integration from the ground up.

Pros

  • Can be customized to fit the needs of your organization
  • Certain API integrations may be less complex to build

Cons

  • Can come at an extremely high cost, as it takes your colleagues with a technical background a significant amount of time to develop and maintain each integration
  • It’s an unscalable solution, as you likely have hundreds of apps that you’d like to integrate
  • It can’t deliver real digital transformation as building integrations doesn’t dramatically change your organization’s core workflows

3. 3rd-party API integration: When you use a middleware platform to implement the integration.

Pros

  • Can help you integrate several apps quickly and securely
  • Normally provides support for existing connectors while adding new connectors over time
  • Users can access a single dashboard for monitoring the integrations

Cons

  • It requires technical skills, which prevents the team at large from building integrations
  • It can take a long time to get comfortable with the platform and to build integrations at scale
  • It can’t deliver real digital transformation as building integrations doesn’t dramatically change your organization’s core workflows

You’ve likely noticed a common thread across these options: They can’t transform the core operating processes at your organization. What can? Read on to find out.

How Workato is different 

Workato, the leader in integration-led automation, allows your team to integrate SaaS apps, on-prem systems, etc. AND build end-to-end automations across core processes without writing a single line of code. 

The platform makes this possible by providing access to thousands of pre-built connectors and by allowing you to build automations that run on event-based triggers
