What are projects?
A project resides in a specific region (cannot be changed later on) and contains other resources like events, endpoints, api keys, etc. While creating a project, you can specify the retry mechanism as either default, exponential or constant, and it’s parameters which control how retries happen on unsuccessful deliveries. More details on different retry mechanisms, their parameters and how they work here.
If the project is not set, accessing any resource like events, endpoints, api keys will redirect to home page asking to select or create a project first.
