As your organization looks to build internal or customer-facing integrations, youâll have the option of implementing them either in-house (i.e. native integrations) or through a 3rd-party solution.
This decision isnât so simple and the right solution can vary by organization, as there are a number of inputs to consider.Â
To help you decide whether to build integrations in-house or outsource their development and maintenance, weâll go deep on the former and then explore your options in the latter.
Itâs an API-based integration thatâs built and maintained by your engineers. The integration can either be between your internal applications or between your product and one of your customersâ applications.

To help clarify this definition, letâs explore how it differs from similar concepts:
Native integrations are an approach to building integrations, while APIs are endpoints that let you access specific data or functionality from a 3rd-party application.
Custom integrations are bespoke integrations that meet the needs and wants of a specific client, while native integrations are a method of implementing integrations.Â
Native integrations donât rely on a 3rd-party provider; the engineers themselves are managing all of the work. Third-party integrations, on the other hand, are any integrations that need to be built and/or maintained in a specific platform.Â
To help crystallize our definition, letâs break down a few common use cases:
Letâs say you use a marketing automation platform, like HubSpot, to collect, engage, and nurture leads.Â
To help your marketers better understand the leads that come inâso that your marketers can nurture these leads effectivelyâ, you can integrate your marketing automation platform natively with a data enrichment tool, like Clearbit.Â

Once connected, you can build a flow where any time a new lead comes into your marketing automation platform, the data enrichment tool automatically performs an email lookup to identify key information on the lead (such as their role and department) and their employer (such as the companyâs name, industry, size, location, etc.).Â
Regardless of the product you offer, you need users to get added to it quickly, easily, and without any issues. Itâs only then that your clients are likely to adopt your solution and that new hires can discover it early on.Â
To ensure this happens, you can connect your product natively with your clientsâ HRIS solution and build an automated provisioning workflow. More specifically, once an employee is added to the HRIS, theyâre automatically added as a user in your product with a certain role (auto-assigning a userâs role depends on the rules a client sets in your application).
The information provided by customer-facing integrations often comes from comprehensive and up-to-date data sources, like a CRM, a marketing automation platform, an HRIS, a ticketing tool, etc.
Pulling clientsâ data from these sources can, as a result, enhance your productâs AI and machine learning features and capabilities for clients.Â
For example, letâs say you offer a sales automation solution that helps sales teams identify the likelihood that a given opportunity closes.

By connecting your clientsâ CRM, marketing automation platform, among other applications that store data on prospects and clients, with your product, it can gather a wide range of information on the opportunities that have closedâand those that havenât.Â
These insights, in combination with other information, allows your productâs AI recommendation engine to provide more accurate predictions on a given deal over time.
Here are some reasons to invest in native integrations:
As you likely know all too well, there are several costs associated with investing in a 3rd-party.Â
Thereâs, of course, the monetary investment. But thereâs also a time investment for evaluating 3rd-party providers, engaging with the chosen vendor on recurring calls, holding renewal conversations, and so on. In addition, thereâs a security riskâwhich is especially pronounced in the integration space, where the vendor can gather and store confidential employee, client, and prospect information.
Native integrations allow you to bypass these costs and risks entirely, saving your team time and potential headaches.Â
If you only have a few integrations you want to build or the scope of these builds are relatively shallow, then native integrations can be the best approach. This is especially true if you feel comfortable allocating engineering resources toward your integration projects.
Relying on 3rd-party providers to manage your integrations can be risky (although this greatly depends on the vendor you select). Their platform can go down, they can decide to stop offering certain integrations, they can modify integrations in ways that hurt their performance, etc.
Native integrations let you avoid these risks and put all of the control in your engineersâ hands, instead.Â

Native integrations can also cause significant issues. Here are a few to keep in mind:Â
Connecting to an API and maintaining that connection requires significant time and effort for a select group of engineers. Given this level of resource investment, the prospect of scaling your integrations to the level that you and/or your clients want is likely impossible.Â
The engineers who can build and maintain your API connections are likely also capable of building or enhancing other high-value features for your product as well as addressing issues that are hurting your organization and/or the client experience. In other words, thereâs a steep opportunity cost to having these engineers build and maintain integrations, and in many cases the cost exceeds the potential benefits.
Unfortunately the most time-consuming part of integrations isn't the initial build, it's the long-term maintenance. Oftentimes APIÂ response bodies can vary and APIs can return data that looks wildly different from what you have seen before, causing your integration to break and requiring your engineers to reinsert themselves into the code base and make bug fixes.

Using native integrations, youâll likely only have a handful of employees who can build and manage them. If any of these employees decides to leave, they might end up taking valuable information on your integrations with them, which can ultimately cause your team to move slowlyâor even be unable to respondâwhen certain integrations break or need to improve.
After reviewing these pros and cons, you may end up deciding that native integrations arenât the best solution for your organization. This then begs the question: Which 3rd-party integration platforms should you evaluate and consider?Â
The answer largely depends on whether youâre looking to build customer-facing or internal integrations. In the case of the latter, you can use task automation tools (e.g. Zapier), an integration platform as a service (e.g. Tray.io), robotic process automation software (e.g. UiPath), among a few other options.
In the case of the former (product integrations), you also have several options:Â

If youâre looking to build customer-facing integrations, unified API solutions may be the most suitable approach. Youâll still need technical resources to use and maintain the other types of solutions, and theyâll force you to build integrations one at a timeâboth of which prevent your team from building integrations at scale. A unified, or universal, API solution, in contrast, lets you build to an API once and then access multiple integrations within a software category (e.g. CRM).Â
But not all universal API solutions are equal. Merge, the leading unified API platform, stands out by letting you offer hundreds of integrations across key software categories, from CRM to file storage to ticketing to accounting. The platform also provides comprehensive common models, features to access and sync custom objects and fields, robust integration management features, enterprise-grade governance and security controls, and much, much more.
