Google Slides redirect uri mismatch

What are you trying to achieve?

I am trying to configure the Google Slides module so I can access a presentation.

Steps taken so far

I am using a @gmail account, not a Workspace account.

I’ve gone through this three times to make sure I didn’t miss anything: https://www.make.com/en/help/apps/file-and-document-management/google-slides#create-and-configure-a-google-cloud-console-project-for-google-slides

I’ve added all the redirect uris I can possible find .

No matter what I try (published vs testing, clearing cookies, trying in private browser, adding scopes, making sure I’m only logged in with the gmail account associated with cloud console, etc) I get one of two issues:

  1. redirect_uri mismatch (this isn’t happening now that I have a stupid amount of redirect uris defined)
  2. the authentication will SEEM to go through but then clicking to select “Presentation ID” in the module config just gives me a “couldn’t load data” error.

I’m beginning to think this integration is broken, which makes sense since it’s extremely convoluted to start with.

Is it possible to use the Oauth2 HTTP module to make a “Create a Slide from a Template Slide” call to the Slides API? Perhaps the Google-Slides-specific module is not viable?
