Guidance for where to place API calls in the react component lifecycle when web part is lazy loaded on page

[wobba]

SPFx lazy load some web parts when they are scrolled into view. Is there any guidance on the react component lifecycle on where API calls should be placed in order not to fire them before the web part is scrolled into view?

onInit/ componentDidMount / render etc.
