Custom Connectors Overview

What Are Custom Connectors?

Custom connectors are special in Power Platform. They let your apps talk to almost any online service. You can make them with a simple interface. You do not need to write lots of code. You just explain how your connector should talk to another system. This lets you get data or send updates to places standard connectors cannot reach.

Tip: Custom connectors let you build a bridge between Power Platform and any API you want.

Standard connectors work for common services like SharePoint or Outlook. Sometimes, you need to connect to a different system. That is when custom connectors help. You can make them fit your needs. You choose how your connector works, what data it uses, and how it keeps things safe.

Why Makers Use Them

Custom connectors give you more control and flexibility. They help you fix problems that standard connectors cannot. Here are some reasons why makers pick custom connectors:

• You can make special solutions for your business.

• You get more features and better control over security.

• You can change your connector as your business grows.

• You can make it work with any system, even if it is only for your company.

Many makers use custom connectors for things like these:

• Connecting with a special CRM system to get and send customer data.

• Linking with an analytics tool to get updates right away using webhooks.

Custom connectors are great because you can build what you need. You do not have to wait for someone else to make a new connector. You can make your own and add hidden features to help your work. This helps you keep up with changes and find new ways to use Power Platform.

Hidden Features of Custom Connectors

You may think you know custom connectors well. But there are secret features that make Power Platform projects smarter and easier. Let’s look at these features together. Each one helps you do tasks faster, connect to more services, and fix problems quickly.

Dynamic Schema

Have you ever wanted your connector to work with different data? Dynamic schema lets you do this. You can set up your connector to change how it sends and gets data. It can switch formats based on what you need right then. You do not have to use just one setup.

• You can use dynamic properties in requests and responses. This works with many REST APIs.

• You can change endpoints and headers to match your needs.

• You can build connectors that change for different cases. This makes your connections more flexible.

Tip: Use dynamic schema with APIs that send different data each time. You will save time and make fewer mistakes.

Custom Triggers

Custom triggers are secret features that make automations work better. You can set your connector to start a flow when something happens in another system. For example, you can start a Power Automate flow when a new record shows up in your CRM.

Custom triggers help you do tasks without doing them by hand. You can connect your business apps and let them share information. This makes your work smoother and saves you effort.

To use custom triggers, you need a few things:

• A valid OpenAPI definition.

• The right place to build connectors.

• Supported authentication methods.

• Use the Power Automate portal to set up and test triggers.

• Make sure your OpenAPI definition has a valid x-ms-trigger.

• Add a webhook or polling trigger in your OpenAPI definition.

Note: Custom triggers let you make connectors that react to events. Your flows start on their own.

Policy Templates

Policy templates are another secret feature that helps you control your connector. You can set rules for things like rate limits, caching, or security checks. This means your connector always works the way you want.

You do not need to write code for these rules. You can pick from templates in Power Platform. For example, you can block requests from some IP addresses or limit how many times someone can use your connector each hour.

Tip: Use policy templates to keep your connectors safe and working well. You can change them anytime as your needs change.

Advanced Authentication

Security is important when you connect to important data. Advanced authentication is a secret feature that keeps things safe. You can pick from over 30 ways to log in, so you always find one that works for you.

You can set up passwordless logins or use multifactor authentication. You can also change rules based on where the user is or what they are doing. This keeps your data safe and makes it easier to control who gets in.

Postman Collection Integration

If you use Postman to test APIs, you will like this secret feature. You can bring your Postman collections into Power Platform. This makes building custom connectors much faster.

1. Bring your Postman collection into Microsoft Flow. The platform makes the custom API description for you.

2. Setting up authentication is easier because Postman fills in details if it can.

3. Actions are set based on your collection, so you can build workflows without lots of code.

Want to get the most from Postman collections? Here are some good tips:

1. Organize tests into collections to keep things neat.

2. Use environment variables for flexible testing.

3. Set up scripts before requests to prepare data.

4. Add checks to see if responses are right.

5. Chain requests for full testing.

6. Watch API performance often.

7. Use version control to track changes.

Tip: Postman integration helps you go from testing to building connectors in just a few clicks.

Enhanced Error Handling

Troubleshooting can slow you down. Enhanced error handling is a secret feature that helps you fix problems faster. Your connector gives you clear error messages and codes that match standard HTTP status codes. You know right away what went wrong.

You do not have to guess or search for answers. You see the exact problem, so you can fix it and get back to work. This saves you time and keeps your flows running well.

Note: Enhanced error handling helps you find problems early and fix them fast.

You have just learned how secret features in custom connectors can change how you build and automate in Power Platform. Try these features in your next project and see how much easier your work gets.
