The Slack Integration That Looked Simple (Until It Wasnāt)
A product team needed real-time alerts sent to Slack.
Someone said:
āWhy build this ourselves? Letās just integrate.ā
Everyone agreed.
The integration shipped fast. People celebrated the speed.
But then:
- Slack rotated an API token ā Alerts silently stopped
- Webhooks timed out ā Customers didnāt get notifications
- Support tickets increased ā Users assumed the product was broken
- Engineers were paged late at night ā Maintenance chaos began
The team didnāt just integrate a feature.
They adopted a perpetual dependency.
What felt like a shortcut became an ongoing babysitting job.
š§ The Illusion of Speed
Integrations feel fast because they avoid reinventing the wheel.
But every integration introduces long-term hidden cost:
- Someone elseās uptime becomes your uptime
- Someone elseās API changes become your emergencies
- Someone elseās roadmap becomes your risk surface
- Someone elseās failure becomes your failure
Integrations promise speed.
But often rent you someone elseās chaos.
šø The Hidden Maintenance Tax
The real cost is not in building the integration.
Itās in supporting it for the next 3ā7 years.
Common slow-burn failure patterns:
- Webhooks that fail āsometimesā
- Sandbox environments that behave differently from production
- Version upgrades that break quietly
- Credential expirations that no one remembers to renew
These arenāt dramatic outages.
They are drips of operational friction that drain time, morale, and support budget.
Quiet failures are the most expensive ones.
š§© The 4 Types of Integrations (And How to Decide)
1. Core Product Integrations
- These define your identity and value.
- Build with care. Own the logic.
2. Critical Workflow Integrations
- Used daily inside business workflows.
- Monitor. Alert. Automate failovers.
3. Customer-Requested Integrations
- Validate usage before committing.
- Donāt build for one loud user.
4. Nice-to-Have Convenience Integrations
- This is where teams waste the most.
- If it doesnāt move a key metric, donāt do it.
šļø When to Build vs. When to Integrate
- If it differentiates your product ā Build.
- If itās a commodity capability ā Integrate.
- If your team canāt maintain it long-term ā Donāt build OR integrate until you solve ownership.
Your moat is not the feature itself.
Your moat is how maintainable it is when things break.
šÆ Leadership Checkpoint
Before approving any integration, ask:
āWho owns this when it breaks at 2:17 AM?ā
If the room goes silent ā
you donāt have a strategy. You have a risk.
Ownership clarity is the real architecture.
ā Key Takeaway
Integrations are not shortcuts.
They are commitment contracts.
Speed without sustainability is debt disguised as progress.
Next time someone says āWeāll just integrate it,ā ask:
āAre we prepared to maintain this forever?ā
That one question prevents months of firefighting.
Have you seen a āsimple integrationā turn into a long-term maintenance headache?
Drop your story ā weāve all been there. š
