Hi Becky,
Much like the 302 redirect, 307 is another temporary redirect.
Whilst there have been studies which showed long term temporary redirects being the same as a 301 permanent redirect, best practice is to use a 301 redirect.
For a further explanation I refer to the Moz Redirection guide - https://moz.com/learn/seo/redirection
I hope this helps answer your question, please let me know if you need anything else.
