Is there a way to create a stack in pulumi cloud for GCP without a project id ? Id like the project creation also be in IAC. On the GUI it seems to be mandatory to include a project id in all the templates for example.

Do you mean, Pulumi projects? No, stacks are within a project. You can have stacks with the same name in different projects. What's the problem you're trying to solve?

Im not sure what the terminology is in pulumi as im new. Im coming from the terraform space where we have terraform workspaces . We are creating a new gcp project id under our gcp org and would want the gcp project creation part of our IAC. My understanding of a stack in pulumi is like a workspace in terraform.

A stack is another instance of the same set of infrastructure. So that sounds about right. So in your question, a project ID is a GCP concept, not a Pulumi one? If that's right, then I don't know the answer. This doesn't seems like a question for #C02DM3GH4TY, which is about the Pulumi application web UI and API. You might be better off asking in #CRFUR2DGB
