APIs are not always the most glamorous part of your tech stack, but they are super powerful.

When it comes to functions like automating workflows, connecting apps, or enhancing your product’s capabilities, APIs can help streamline your operations and improve overall efficiency. 

As a growing business, you want to choose the right API to ensure you avoid technical roadblocks and set yourself up for scalable success. But with all of the options available, it can be tricky to know which API is the best fit for your needs.

In this article, we’ll cover the key factors that you should consider when selecting an API, plus a whole lot more.

What is an API?

An API is a set of rules that allows a software application to interact with another.

You can think of it as a bridge between systems that lets your different software communicate with one another, share data, and automate tasks, all without making you build an entire software from scratch. 

As an example, you might want the ability to automatically send documents (like contracts, proposals, etc.) for eSignature without having to leave your CRM. A solution like PandaDoc API can make this possible with embedded eSigning.

How to find the right API for your needs

It’s definitely worth jumping into product demos and pricing plans (and you’ll get there). But first, let’s take a step back and consider your broader business needs.

Here are some questions to consider:

  • What problem are you trying to solve?
  • Which processes need to be smoothed out or automated?
  • What platforms or tools does this API need to integrate with?
  • Are you looking for a long-term solution that can scale with your business?

Of course, there’s no one type of API that fits everyone’s needs—it comes down to what your goals are. REST APIs are a common choice since they are simple and flexible, but other types (like GraphQL or SOAP) could work better depending on your specific use case.

This is where your internal developers or outsourced team can help assess all the technical aspects, while the main API strategy should start with understanding your business needs.

Key considerations when evaluating an API

When you have a clear direction to go in, you can start evaluating your options.

Here are the top factors to consider:

Security and compliance

It goes without saying that you need to keep your data safe. APIs are usually dealing with sensitive information, so your provider should be following best practices for encryption, authentication, and compliance. This could include GDPR or HIPAA, depending on your industry.

For example, PandaDoc eSignature software is E-SIGN, UETA, and HIPAA compliant, plus it’s backed by SOC2 certification, so you can sign all your important docs with confidence.

Integrations

A good API needs to work well with your existing systems, whether that’s your CRM, payment processor, or document management software. Native integrations or third-party connectors can also simplify the setup.

Scalability

It’s highly likely that you want your business to grow, and that means your API should grow with it. Make sure to look for services that can support high-volume usage, reliable uptime, and performance that won’t get worse as the demand increases. 

Support and documentation

Your API should have clear and detailed documentation. This will help reduce development time and troubleshooting. It’s even better if your provider offers a developer portal, sandbox environment, or dedicated support.

Costs

Obviously, cost can be a factor when deciding which route to take. Some APIs are free with limited capabilities and only charge as your needs increase, while others have flat-rate or tiered pricing. It’s important to factor in both short- and long-term costs, like potential charges for overages or if you want premium support.

How to test and evaluate an API before committing

The saying goes for APIs, too—try before you buy.

Here are some ways to test before making a commitment. 

Use free trials or sandbox environments

It’s common for reputable APIs to offer free trials, demos, or sandbox environments that allow you to test the API’s functionality without impacting real data. 

PandaDoc offers a free trial with access to the Sandbox API.

Understand the limitations

Like most things in life, no API is perfect. Some plans may have usage caps, rate limits, or data restrictions that can affect performance. It’s a good idea to know what these limitations are from the get-go to see if they align with your situation.  

Test real use cases

Chances are that the API will work, but the question is, will it work for you? Make sure you try out actual business scenarios, like sending documents for approval or syncing contacts between platforms.

For example, if you’re ready to build and test document workflows in a sandbox environment, check out PandaDoc’s guide to embedded use cases here.

Benefits of using an API

When done well, implementing APIs can add a ton of value to your business.

Here’s how:

  • Increased efficiency: With APIs, you can automate manual tasks to save time and reduce errors.
  • Greater flexibility: You can choose the best tools for you without being locked into one platform.
  • Faster innovation: APIs allow you to build new features or services without starting from scratch.
  • Improved customer experience: The right API should create smoother, more integrated workflows that better serve your users.

Final thoughts: Choosing the best API for your business

APIs are a key part of technology in business today, so choosing the right one is crucial to driving growth, efficiency, and innovation. Just make sure you select an API that supports your long-term success.

PandaDoc’s API provides seamless native integration, allowing you to automate your document workflows, save time, and focus on scaling your operations. 

When Colonies integrated the PandaDoc API into their platform, they reduced application processing time by 25%, helping them provide an easy, in-app leasing process for their tenants.

“PandaDoc’s API integration has been a transformative tool for Colonies as we continue to scale across new properties and countries. Each lease is automatically tailored to meet regional legal requirements and property specifics, saving countless hours in document preparation and significantly reduced errors. Automating these processes within our platform has not only improved tenant satisfaction but also empowered our team to focus on expanding our reach and enhancing our offerings.”
