As your company looks to connect SaaS applications with your product in-house, youâll likely face a number of obstacles.
And while these challenges can look different depending on the specific integration scenario you face, we discovered through our research that companies often run into a common set of challenges.Â

You can read on to learn more about the most common challenges of building product integrations.Â

In the context of product integrations, itâs especially important that companies build high-performing integrations. After all, these integrations impact clientsânot just your business.
Integrations with syncs that often fail, take a long time to process, run infrequently, or only work for a limited set of data can ultimately disappoint clients.Â
As a result, your team needs to invest enough time and resources on building, testing, and fine tuning the integrations before taking them to market.Â
SaaS integrations can also be incredibly difficult to scale when managed in-house.
Youâre relying on a small group of developers who understand the APIs of the associated applications youâre looking to connect and who can stitch together the applications with your product via custom code.Â
Since these engineers are, in most cases, uniquely positioned to tackle projects for your core product, you likely canât afford to allocate allâor even anyâof them to your integration projects.Â
Building more integrations will also likely require forming additional partnerships with 3rd parties and allocating more support resources to help manage integration issues. The former is often a lengthy process (although it depends on the vendor) and both demand significant investments in time from your team.
As you account for all these resourcing requirements, youâll likely find that integration builds and resource investments arenât neatly correlated; building more integrations requires an increasing rate of resource investments.

Despite the benefits of offering centralized, easy-to-follow, up-to-date, and comprehensive API documentation, many organizations fail to do so.
Here are some of the issues your developers might run up against for just a single API provider:
As a result of these issues, your developers will likely have to invest significant time on just finding the information they needâassuming they find it in the first place.
While this challenge didnât top the list in our research, itâs worth considering.
Since only a few employees can participate in the process of building your integrations, itâs imperative that they stay with your company throughout the duration of the build. If any of your builders leave during the process, your implementation timeline can get extended; in some cases, the employees leftover may not even have the expertise needed to continue the integration project, leading the project to end shortly thereafter.Â
When in-house engineers finally decide to embrace 3rd-party integrations over native builds, the transition is often anything but seamless.Â
More than 2 in 5 respondents (42%) from our study said that 3rd-party integration solutionsâlike an embedded iPaaS (e.g. Workato Embedded) or a task automation tool (e.g. Zapier)âarenât intuitive and easy to use.Â

As a result, your engineers are likely forced to use these tools themselves, which largely negates the benefits youâd hope for when going the 3rd-party route.
