Many people think Power Apps is about screens, buttons, and forms.
But in real businesses, those things are just the interface.
What actually makes an app useful is its ability to:
● Read and write business data
● Send emails and notifications
● Trigger approvals
● Connect to databases
● Integrate with enterprise systems
● Talk to external services
All of that happens through connectors.
If you understand connectors deeply, you move from building “demo apps” to designing real business systems that companies trust with operations, compliance, and customer data.
This guide explains Power Apps connectors in simple, professional language with practical, real-world examples, so you understand not just what they are, but how to choose the right one, how they affect cost, performance, and security, and how enterprises use them at scale.
A Power Apps connector is a bridge between your app and another system.
That system can be:
● A Microsoft service (SharePoint, Outlook, Teams)
● A database (Dataverse, SQL Server, Azure SQL)
● A business platform (Dynamics 365, Salesforce)
● A cloud service (OneDrive, Azure services)
● A custom-built API
● An on-premises system inside a company network
Whenever your app needs to:
● Get data
● Save data
● Trigger an action
● Call another system
It uses a connector to do it.
Think of connectors as the “communication cables” of the Power Platform. Without them, your app cannot interact with the real world.
At a high level, the flow looks like this:
A user performs an action in the Power App (submit, approve, search, update).
The app sends a request through a connector.
The connector talks to the external system.
The system responds.
The app shows the result to the user or triggers automation.
This same mechanism is used by:
● Power Apps (user interface)
● Power Automate (background workflows)
● Power Pages (external websites)
That means connector design affects the entire Power Platform, not just your app.
Power Apps connectors fall into four practical categories:
Standard Connectors
Premium Connectors
Custom Connectors
On-Premises Connectors (via Data Gateway)
This classification is critical because it directly affects:
● Licensing
● Cost
● Performance
● Security
● Scalability
What Are Standard Connectors?
Standard connectors connect Power Apps to common Microsoft services that are already part of Microsoft 365. In many business plans, these do not require a premium Power Apps license.
They are designed for:
● Simplicity
● Speed
● Department-level solutions
● Low-cost deployment
Common Standard Connectors
● SharePoint
● Excel (OneDrive or SharePoint)
● Outlook
● Microsoft Teams
● OneDrive
● Planner
● Forms
Business Problem
An HR team wants a simple way for employees to apply for leave and for managers to approve it.
Connector Design
● SharePoint Connector
Stores leave requests in a SharePoint list.
● Outlook Connector
Sends email notifications to managers.
How It Works
Employee submits leave request in Power App.
App writes data to SharePoint.
Outlook connector sends approval email.
Manager replies or clicks approval link.
App updates the status in SharePoint.
Business Result
● No premium license required
● Fast deployment
● Low cost
● Easy to maintain
When Standard Connectors Are a Good Choice
Use them when:
● You have a small or medium team
● Data volume is low
● Security requirements are basic
● You need a quick solution
● Budget is limited
Limitations of Standard Connectors
● Performance drops with large datasets
● Limited enterprise security controls
● Weak support for complex data relationships
● Poor delegation for filtering and sorting
This is why companies eventually move to Dataverse or SQL for serious systems.
What Are Premium Connectors?
Premium connectors connect to:
● Enterprise systems
● High-performance databases
● Business platforms
● Advanced APIs
They require paid Power Apps licenses (Per App, Per User, or Pay-As-You-Go).
Common Premium Connectors
● Microsoft Dataverse
● SQL Server
● Azure SQL
● Dynamics 365
● Salesforce
● HTTP (Custom APIs)
● SAP (in many regions)
● Oracle Database
Business Problem
A manufacturing company needs a mobile app for warehouse staff to track stock in real time.
Connector Design
● SQL Server Connector
Connects to the central inventory database.
● Power Automate
Triggers reorder workflows when stock falls below a threshold.
How It Works
Worker scans item and updates quantity in app.
App writes data to SQL database.
Power Automate checks stock levels.
If low, sends alert to procurement team.
Dashboard updates automatically.
Business Result
● Real-time enterprise data
● High performance
● Secure access control
● Requires premium licenses
Why Companies Choose Premium Connectors
They provide:
● Better performance at scale
● Strong security integration
● Support for complex business logic
● Enterprise compliance features
● Reliable automation triggers
What Is a Custom Connector?
A custom connector allows Power Apps to connect to any system that exposes a REST API, even if Microsoft does not provide a built-in connector.
You define:
● Authentication method
● API endpoints
● Request structure
● Response format
Business Problem
A training institute wants to accept online payments through a custom payment platform.
Connector Design
● Custom Connector
Connects to the payment provider’s API.
How It Works
Student enters payment details in app.
App sends request via custom connector.
Payment API processes transaction.
API returns success or failure.
App updates enrollment status in Dataverse.
Business Result
● Full integration with external platform
● Complete automation
● Requires premium licensing
● High flexibility
When to Use Custom Connectors
● Legacy systems
● Proprietary business platforms
● Third-party services without built-in connectors
● Internal company APIs
What Is the On-Premises Data Gateway?
Many companies still store data inside their own data centers.
The On-Premises Data Gateway creates a secure tunnel between:
● Power Apps in the cloud
● Local systems inside the company network
Business Problem
HR data is stored in an internal SQL Server for compliance reasons.
Connector Design
● SQL Server Connector
● On-Premises Data Gateway
How It Works
Power App sends request.
Gateway securely passes it to internal database.
Database responds.
Gateway sends data back to app.
Business Result
● Cloud app with on-prem data
● Secure access
● Premium licensing required
Not all connectors behave the same way.
Read Connectors
● Fetch records
● Get files
● Retrieve lists
Write Connectors
● Create records
● Update entries
● Delete data
Action Connectors
● Send emails
● Start approvals
● Trigger workflows
● Call APIs
A single app screen can use all three types at once.
Power Apps often triggers Power Automate flows.
Example:
User submits form in Power App.
Dataverse connector saves data.
Flow runs.
Outlook connector sends email.
Teams connector posts notification.
SQL connector logs transaction.
This chain can involve five or more connectors in one business action.
Delegation determines where data processing happens.
Delegable Connectors
Processing happens at the data source.
Examples:
● Dataverse
● SQL Server
Non-Delegable Connectors
Processing happens in the app.
Examples:
● Excel
● Some SharePoint operations
Why This Matters
If your app loads 50,000 records:
● Delegable source → database filters data
● Non-delegable source → app tries to handle everything
This is why enterprise apps almost always use Dataverse or SQL.
Security works at three levels:
Authentication
Who is allowed to connect?
● Microsoft login
● Service account
● API key
● OAuth token
Data Permissions
What can they do?
● Read only
● Create
● Update
● Delete
Platform Governance
What connectors can be used together?
This ensures sensitive data stays inside approved systems.
DLP policies control:
● Which connectors can share data
● Which connectors are blocked
Example
Allowed:
● Dataverse + Outlook
Blocked:
● Dataverse + Gmail
This prevents confidential data from being sent to personal accounts.
| Connector Type | License Impact |
|---|---|
| Standard | Usually included with Microsoft 365 |

● Apply DLP policies early
● Separate dev and production environments
● Monitor connector usage and performance
Many people can build screens.
Few can:
● Design cost-efficient architectures
● Choose the right connector strategy
● Prevent data leaks
● Optimize performance at scale
Those few become:
● Power Platform Developers
● Solution Architects
● Enterprise Consultants
Microsoft is investing in:
● AI-assisted connector configuration
● Smarter delegation handling
● Faster API integrations
● Advanced governance controls
This means connector design will become even more critical.
Power Apps connectors decide:
● What your app can do
● How fast it runs
● How secure it is
● How much it costs
If you master connectors, you move beyond building tools and start designing enterprise-grade digital platforms.
That is the difference between learning Power Apps—and becoming a professional in the Power Platform ecosystem. Formal Power Apps Training is essential to master these concepts.
