API Call Key Question

Is the a key needed when making a Get All API call?

That would depend which API you are using. Generally, all API have authentication and does need a key or other methods to authenticate.

What about the Bubble API?

Is there a key used for GET ALL ?

Could you explain in detail what you are trying to achieve?

I wanted to elaborate on what I meant here as now I have much experience with Bubble and understand where I went wrong in my question.

There are two types of endpoints that I can create in Bubble. The Get All I was speaking about was asking about pulling all records using the Data API. The key I needed to create was in the Settings > API > Generate new API token.
