I am creating a custom connector for an API that supports Basic Auth, but the API key is used as the User Name and the Password should be left blank. Does anyone know if this is possible, when I try and use the connector it is mandating that I enter in the password which I presume is failing it. Error returned is below, I did the some tests in Postman and with the User Name only it works and with Password define it returns the same error as I get when creating Custom Connector.

{

"error": "Invalid Authorization header",

"type": "ch:service"

}

Basic Auth with no Password

I worked it out.

In our business, we have an API with our bank which we use to take payments on schedule. The banks API specifically requires that there is NO PASSWORD sent with authentication.

After trying everything, the winning combination is selecting "Raw" authentication and putting your Basic XXXXndkNdkds384ljLetc... in the "Value" box. Something like this:

Re: Basic Auth with no Password

Hi @Dobadino ,

Not sure if this will be helpful, and maybe you've already found a solution in the past ~18 months, but I was able to work around this issue by adding a single space (" ") as the password for the API I was building a custom connector for. It would be nice if we as the custom connector developer could have the option to make the password optional, but this has proved to be a solid workaround for me.

Hope this helps!
