Question

Username already exists

I'm trying to create an integration between Plug&Pay and LearnDash using the official Zapier integration.

It works for new users, but when an existing WordPress user purchases another course, Zapier tries to create the user again instead of enrolling the existing user into the new course. As a result, I get the error: "User could not be created. This username already exists."

How can I enroll an existing user in an additional course without creating a new user account?

Hi ​@leidagroot 

Try reaching out to LearnDash Support for help with their Zap app integration that they created and manage using the Zapier Developer Platform.

 

For us to have more info, post screenshots showing how your Zap steps are outlined and configured, along with the encountered error.

Hi ​@leidagroot 

First, you are using a deprecated Zap trigger event, so that needs to be updated.

 

Click the Username field to see the tooltip that may have more info about expected values/formats.

 

Check to make sure you are using the correct version of the LearnDash Zap app integration as there appears to be an updated logo.
