Once you configure an API call, you need to initialize it. If you don't, it will not appear in the Bubble Editor. Please note that initializing a call actually runs/executes it. If a call deletes an item or creates an item that requires a unique id, the Initialize call button will, if successful, delete or create the item. Thus, the next call will likely fail since the item already exists or was deleted. To initialize an API call with mandatory parameters and no sensible default, you can set a default as an example, click to “Initialize,” then unset the default.
