Connecting your CRM to the rest of your tool stack generally happens one of two ways: a native integration built and maintained directly by the CRM vendor (or the other tool’s vendor), or a third-party integration platform (like an iPaaS or automation tool) that connects the two through its own middle layer. Each approach has real trade-offs that matter beyond which one is technically easier to set up initially.

How Native Integrations Work

A native integration is built and maintained by one of the two vendors involved — either the CRM vendor building a direct connection to a popular tool, or vice versa. These integrations typically offer deeper, more reliable functionality because they’re purpose-built for the specific pairing, and they’re maintained by a team with direct access to both systems’ APIs and roadmaps.

The trade-off: Native integrations only exist for tool pairings popular enough to justify the vendor’s investment in building and maintaining them. If you use a less common or newer tool, a native integration may simply not exist.

How Third-Party Integration Platforms Work

Tools like iPaaS platforms or workflow automation services sit between your CRM and other systems, using each system’s API to move data back and forth according to rules you configure. This approach can connect virtually any two systems that have an API, regardless of how common the pairing is.

The trade-off: You’re now depending on a third system (the integration platform itself) in addition to the two you’re actually trying to connect, which adds a point of potential failure and ongoing maintenance. Complex integrations built this way can also become fragile — when either underlying system changes its API, the integration platform’s connector needs to be updated too, sometimes with a lag.

A Side-by-Side Comparison

Factor	Native Integration	Third-Party Platform
Setup complexity	Usually simpler, built for the specific pairing	Requires configuration within the integration platform
Depth of functionality	Generally deeper for the specific pairing	Can be shallower, limited by what the platform’s connectors expose
Tool coverage	Limited to popular, vendor-supported pairings	Broad — can connect almost any API-accessible tool
Maintenance responsibility	Handled by the vendor(s)	Partly your responsibility to monitor and maintain
Cost	Often included, sometimes a paid add-on	Usually a separate subscription cost
Failure point	Fewer — two systems involved	More — three systems involved (CRM, other tool, integration platform)

How to Decide Between the Two

Check for a native integration first. If one exists and covers your actual use case, it’s generally the simpler, more reliable starting point, especially for your most business-critical connections.

Use a third-party platform for coverage gaps. For tools without a native integration, or for connecting multiple systems in ways no single native integration supports, a third-party platform fills a real need that native options can’t.

Reserve third-party platforms for lower-stakes connections when possible. Given the added point of failure, it’s worth being more cautious about routing your most business-critical data flows (core deal and customer data) through a third-party layer compared to lower-stakes, supplementary data flows where an occasional sync hiccup is more tolerable.

A Hybrid Approach Is Common

Most organizations end up using both: native integrations for the handful of tools with deep, vendor-supported connections (often email, calendar, and one or two core business tools), and a third-party integration platform to fill in the gaps for everything else. This hybrid approach is not a compromise — it’s generally the most practical way to get both reliability where it matters most and flexibility where coverage would otherwise be missing.

Frequently Asked Questions

Are third-party integration platforms less secure than native integrations? Not inherently, but they do introduce an additional vendor with access to your data flowing between systems, which is worth factoring into your security and vendor-risk evaluation. Reputable integration platforms maintain strong security practices, but it’s a legitimate additional consideration beyond a direct two-party native integration.

How do we know if a native integration is actually well-maintained versus neglected? Check the integration’s update history or changelog if available, and look for recent reviews specifically mentioning integration reliability. A native integration that hasn’t been updated in a long time, especially if either underlying platform has changed significantly, is a reasonable reliability concern worth investigating before depending on it.

Can we switch from a third-party integration to a native one later if one becomes available? Generally yes, and it’s often a worthwhile upgrade when a native option appears for a connection you’ve been running through a third-party platform — native integrations typically offer better reliability and depth once available, justifying the migration effort.

Do third-party integration platforms typically charge based on usage volume? Many do, with pricing tied to the number of automated tasks, data records processed, or similar usage metrics. This is worth factoring into your cost comparison, since a high-volume integration can become a meaningful ongoing cost beyond the platform’s base subscription fee.

Is it reasonable to build integrations in-house instead of using either option? For organizations with dedicated development resources and highly specific integration needs that neither native options nor third-party platforms address well, custom-built integration is a legitimate third path — but it comes with the highest ongoing maintenance burden of the three approaches, since you’re now solely responsible for keeping the integration working as both connected systems evolve.

How should we think about integration strategy when evaluating a new CRM, before any integrations are actually built? List your must-have and nice-to-have tool connections as part of your core CRM requirements, not as an afterthought once the platform is chosen. Checking native integration coverage for your specific stack during evaluation — rather than discovering gaps after migration is already underway — avoids committing to a platform that looks strong on core CRM features but creates unexpected integration work for tools central to how your team actually operates.

Next Step

List your must-have tool connections and check for a native integration on each before defaulting to a third-party platform — reserving the added complexity of a middle layer for genuine coverage gaps keeps your overall integration architecture simpler and more reliable.
