As you look to build integrations with your product, youâll likely consider two implementation options: developing and maintaining the integrations in-house and outsourcing them to a 3rd-party.
Weâll break down why the 3rd-party approach, more specifically, using a universal API solution, is often the best choice by highlighting its benefits. But to start, letâs cover what universal APIs are and the vendors you might come across.
A universal API, also known as a unified API, is an aggregated API that lets you build multiple integrations between your product and 3rd-parties for a given software category (e.g. HRIS).Â

You can find a broad range of universal API vendors in both B2B and B2B2C. In addition, the vendors youâll come across will likely vary based on the category of software youâre interested in integrating with.Â
For instance, Codat and Rutter offer a universal API for accounting and payment platforms; Finch and Kombo offer a universal API for HR systems; Nylas and Cone offer a unified API for email; Vessel offers a universal API for GTM tools; and Merge, which strives to be the one-stop-shop for all B2B integrations, offers seven (and growing) unified APIs across popular software categories, including HRIS, ATS, CRM, file storage, marketing automation, ATS, and ticketing.Â
To give you a better idea of how your team can use universal API solutions, letâs break down a few use cases.
To help users adopt your product quickly and easily and ensure they have the appropriate set of permissions over time, you can integrate your product with customersâ HRIS solutions and build the following flows:

Say you offer a compliance automation platform that helps customers perform all of the tasks necessary to comply with certain security and data privacy regulations and audits.
To help customers discover these tasks and work on them, you can integrate your platform with customersâ ticketing platforms and build the following flows:Â

Imagine you offer a gift-giving platform and want to help customers deliver the right gifts to employees at the right time.
To do this, you can connect to customersâ HRIS solutions, sync fields like birthday, start date, job title, etc. and build the following workflow:

Here are just a few reasons why you should invest in a unified API solution:
Your clients are likely evaluating your solution alongside others across a variety of dimensions, from pricing to support to security to integrations. And while each criteria is important, executing a best-in-class product integration strategy is especially influential.
Case in point: Roughly 4 in 5 buyers (81%) say that a vendorâs ability to provide seamless integrations is very important. In addition, when we surveyed hundreds of PMs and engineers for our State of Product Integrations report, we learned that more than half of organizations have been able to use the integrations to improve their close rate.Â

A universal API solution like Merge provides the competitive differentiation you need in your integration offerings, as it allows you to implement dozens in a given category in a matter of days.

If customer-facing integrations arenât absolutely essential to using your platformâbut still provide significant valueâyou can include them in higher subscription plans or make them available as individual add-ons.
This can sway customers into spending more with you over time. And if the integrations are for enterprise applications, like NetSuite, Workday, etc., youâll likely be able to capture more revenue, as larger organizations with bigger budgets probably use these applications.

The process of building and maintaining API integrations in-house is extremely time consumingâand it only becomes more time-intensive as the number of integration projects grows.
Universal APIs take the burden off of engineersâ plates, allowing them instead to focus on initiatives that require their unique expertise, whether thatâs building out or enhancing core product features or resolving technical issues that plague the customer experience and lead to churn.
Your engineers likely donât want to spend significant parts of their day on all of the tasks that come with building integrationsâfrom research API docs to testing the connectionsâand maintaining themâfrom fixing bugs to building to another endpoint.
Universal APIs largely take this work off their plates and allows them to focus on the more exciting projects they had in mind when joining your company.
Once customers adopt your customer-facing integrations, theyâll likely be able to automate critical workflows in your product.Â
Depending on your product and the integrations you make available, this can be anything from automating user provisioning to streamlining ticket management to fast-tracking lead routing.
Since these workflows add additional value to customers, theyâll be all the more likely to stay on for longer.
Prospects in different markets likely use a certain set of applications. For instance, companies in the UK might use an HRIS like Cezanne HR, while companies in Sweden might be more likely to use an HRIS like Hailey HR.
Integrating with the specific set of applications that organizations in your target market use can help remove a layer of friction in expanding to that market successfully, as it gives prospects one more reason to adopt your platform.
Now that you know why universal API platforms are important, the next question is how you go about evaluating and selecting the best platform for your organization.Â
Here are some criteria to help guide your selection process:
âYou might need a specific unified API today, such as a unified API for HRIS, but your future integration needs are likely to evolve and expand. With that in mind, look for vendors that provide several unified APIs across important software categories.

Your end-users will likely need to access a number of objects and fields within your integrations, some of which may be standard while others may be customized.
To ensure the platforms account for all the data thatâs relevant to your end-users, youâll need to review their common models along with their extensibility (i.e. their ability to work with data that lies beyond their common model).Â
Here at Merge, weâve developed comprehensive common models across each unified API category. But we also recognize that each product and end-user might have specific integration requirements. To help meet them, no matter what they are, we offer Field Mapping, which lets you or your end usersâ map data to our common model; Remote Data, which lets you access the most recent data in its original format; and Authenticated Passthrough Requests, which lets you make requests directly to an API.

âMaintaining product integrations on behalf of clients can be extremely laborious and complexâeven more so than building them.Â
Universal API solutions try to address this pain point by providing integration management features, like request and response logs, issue detection, automated alerts, etc. That said, each solution approaches this differently, so take the time to understand the maintenance capabilities offered by each platform; and, if possible, get access to accounts with demo data so you can get hands-on experience with each platform.Â
â

âEven after youâve played around in the platforms and held extensive technical discussions with different vendors, you should take the time to review how the platforms compare on 3rd-party review sites like G2.Â
The reviews can help you confirm each vendorâs unique strengths and weaknesses as well as rule out vendors with overwhelmingly negative reviews. If you want a high level overview, you can also review the G2 GridÂŪ for Unified APIs, which allows you to directly compare the vendors across two axes: satisfaction and market presence.Â
