apikey selection for production environment

[CarolinaTM]

Hi,

While researching the correct use of API keys, I came across some conflicting information. I read that some API keys are meant only for development and testing, while others are suitable for production environments.

I'm still new to this, so I wanted to ask: what is the correct type of API key to use for a public application in a production environment?

I'm currently using the following path:
Content → New Item → Developer Credential → API Key credentials

I just want to make sure that using this option won't result in any misuse or policy violation.

Thanks in advance!
