Yeah, it makes sense… perhaps the best thing to do is create a client side content management-like page, so that I can insert what I need in the entry → wait for the external api call to fill in the rest of the data → create more entries in my collection. Thanks for confirming my doubts 
And what about triggering the creation of entries on other collections after creating one from a different collection? Like I enter an id, and then automatically generating an entry with data coming from an external call to an api passing that id? Perhaps with a lifecycle hook like “afterCreate”?
