How to pass API key in VBA for Get and Post Request?

Question

I am using https://developer.companieshouse.gov.uk/api/docs/ to access an API I have my API key, however, i am not sure how to pass that from VBA. So far i tried below

Answer 1

Basic auth requires the username and password to be base 64 encoded together. The AuthKey you need to pass is essentially:

def unencoded_auth = "[username]:[authkey]"
def encoded_auth = *call-to-base64-encode-value*(unencoded_auth)

Then you would replace

"Basic " & AuthKey

with

"Basic " & encoded_auth

I'll reference this post as to how to achieve the base64 encoding.
