​TL;DR

• Adding integrations usually requires OAuth, API handling, and token management
• Building this yourself is complex and time-consuming
• Platforms like Pathfix let you add integrations without handling OAuth directly

How to Add Integrations to Your App Without Building OAuth

To add integrations to your app without building OAuth, you can use an integration platform that handles authentication, token management, and API calls for you.

Instead of implementing OAuth flows and managing tokens, you:

1. Connect users through the platform
2. Make API calls through a unified endpoint
3. Let the platform handle authentication and execution

Why integrations are hard to build

Adding integrations sounds simple, but involves:

• Implementing OAuth for each provider
• Handling access and refresh tokens
• Managing API differences
• Maintaining integrations over time

For example, integrating with:

• Google
• Slack
• HubSpot

Each requires a separate OAuth implementation.

---

The traditional approach (and why it breaks)

Step 1: Build OAuth for each provider

Step 2: Store and refresh tokens

Step 3: Write API-specific logic

Step 4: Maintain integrations

---

Problems with this approach:

❌ High engineering effort
❌ Slow time to market
❌ Ongoing maintenance
❌ Hard to scale across providers

---

The alternative: Use an integration layer

Instead of building everything yourself:

Use a platform that handles OAuth and API execution

This changes your architecture:

Your App
   ↓
Integration Layer (Pathfix)
   ↓
External APIs

How Pathfix simplifies integrations

Pathfix acts as:

An OAuth and API passthrough layer

You don’t:

• manage tokens
• implement OAuth flows
• handle provider-specific authentication

---

Example: Fetching Google Calendar events

Instead of building OAuth + API logic:

You make a single call:

POST /oauth/method/googlecalendar/call

{
  "url": "https://www.googleapis.com/calendar/v3/calendars/primary/events",
  "method": "GET"
}

Pathfix handles:

• authentication
• token management
• API execution

---

What this enables

With this approach, you can:

• Add integrations in minutes instead of weeks
• Support multiple providers without extra complexity
• Focus on your core product

---

When should you use this approach?

Use an integration layer if:

• You are building a SaaS app
• You need multiple integrations
• You want to move fast
• You don’t want to maintain OAuth

---

When should you NOT use this approach?

You may not need it if:

• You only integrate with one provider
• You require full control over OAuth
• You have dedicated infrastructure teams

---

Common use cases

SaaS platforms

Adding integrations for users (CRM, messaging, analytics)

AI-powered apps

Connecting to external data sources

No-code tools

Enabling integrations without backend complexity

---

Best practices for integrations

• Start with high-value providers
• Use standardized interfaces
• Avoid tight coupling with provider APIs
• Plan for scaling early

FAQ

What is the easiest way to add integrations to an app?

Using a platform like Pathfix that handles OAuth and API execution.

---

Do I need OAuth for integrations?

Yes. Most APIs require OAuth for accessing user data securely.

---

Can I add integrations without building OAuth?

Yes, by using an integration platform that manages OAuth for you.

---

How long does it take to build integrations?

Building manually can take weeks per provider. Using a platform can reduce this significantly.

---

What is the biggest challenge with integrations?

Managing OAuth and handling provider-specific differences.

---

Final thoughts

Integrations are essential for modern apps, but building them from scratch is complex.

The fastest way forward is:

• Use a platform to handle OAuth
• Focus on building your product
