Best Way To Manage Mutliple API Calls?

I have an which gets customer conversations and displays them in a Whatsapp-esque UI.

The problem is that in order to do this, I have to:

- Hit an endpoint that will get the contact information using their email
- Hit an endpoint using their contact id to create a conversation
- If this conversation creation is successful, hit the endpoint to fetch the conversation to display the latest message to the user.

This seems very inefficient at present. Is there a better way to use the API?

Thanks
