Custom connector and login problems

Posted on by Community Power Pla... Microsoft Employee

I developed an application using a custom connector. However, when I share the app with people, it will ask them to enter a username and password. I don't want that. Can I prevent this? I want the username and password I entered to be defined for everyone by default. Is that possible ? By the way I tried to create Power automate flow. But this time, It disrupted the process within the application.

I'm not sure of your question, did you mean?:

The custom connector requires a username parameter and password parameter to be entered and you want that done automatically? or,

You're sharing an app with other people and you don't want them to enter Microsoft credentials in order to use it?

If it is #1, you can potentially default the input parameters of the custom connector to achieve this. That's side-stepping the purpose of the username and password, so that's a risk

If it is #2, that sounds like it is possibly contravening the Microsoft licence agreement - don't do that

Or, is there a different question here?

Hi,
Thanks for reply. Actually my main goal is first option. How can I set it as default? I have to connect with basic authentication. Because I am trying to reach 3rd party application.

OK, here are the steps to make a custom connector perform a defaulted basic authorization using https protocol:

Create/edit your custom connector and choose "No authorization" on the Security tab

Create a Base64 encoded string of the form "username:password" (separated by a colon). You can use a site like this to do it. Copy the resulting string to use again in a moment

When creating the custom connector parameters, make sure to create a Policy that looks like this:

And you will replace the string abc123 with the base64 username:password string you created in Step 2. It is prefaced with "Basic " (there's a space character in there)

Hope that helps,

Bryan
