Problem /w Recaptcha V2 Invisible + Hidden Callback

#1
Hi,

Been working on this for days and I cannot seem to get this to work, so any help would be greatly appreciated!!
I am trying to send a captcha token on the bestbuy.ca login page, specifically:
https://www.bestbuy.ca/identity/glo...tps://www.bestbuy.ca/account/en-ca&lang=en-CA

Once you navigate to this page, you will be redirected and a random tid will be generated and used in the link (not sure if this is relevant)
i.e.
https://www.bestbuy.ca/identity/en-ca/signin?tid=L3BAW3mr4QI1gP9%252FAf2V5bHaWaOyxJU3OUshkHhlG6qQHkZXoa14Hxjqy3USFxZxGaz71C9pbrm%252Fp0NfOKL%252BY%252BXt1j4NyZTgzz5yKSGQvE7enZUxqtnWanulg1CxDz05E7NO7SxD25QzeDZAyp%252FvNfW%252FZdSBcXU5ZbYEe06qPsS0pe7vNb9OJ%252BGCTWmK8X%252FLnw71Y%252BFA17NeuS2h2LXpOkKty9OeWMAILEnpmc0Hv%252BwbqnyYfsKd00kLs1fif7Cd0%252FHbS%252Fmt5be1i2v4%252FveHaPaDd7W5bPkZABSz6OKSgnlDZlejG4pMhWtnBTSOTpiV

1) Inspecting this page, I send over the following details to my captcha service:
sitekey= 6LcJGxsTAAAAAGtISLbbV9VAIbUUzss3t0NFsW2V
url= https://www.bestbuy.ca/identity/en-ca/signin?tid=L3BAW3mr4QI1gP9%252FAf2V5bHaWaOyxJU3OUshkHhlG6qQHkZXoa14Hxjqy3USFxZxGaz71C9pbrm%252Fp0NfOKL%252BY%252BXt1j4NyZTgzz5yKSGQvE7enZUxqtnWanulg1CxDz05E7NO7SxD25QzeDZAyp%252FvNfW%252FZdSBcXU5ZbYEe06qPsS0pe7vNb9OJ%252BGCTWmK8X%252FLnw71Y%252BFA17NeuS2h2LXpOkKty9OeWMAILEnpmc0Hv%252BwbqnyYfsKd00kLs1fif7Cd0%252FHbS%252Fmt5be1i2v4%252FveHaPaDd7W5bPkZABSz6OKSgnlDZlejG4pMhWtnBTSOTpiV
apikey = {captcha_service_api_key}

2) Once I got the solved token, I went ahead and inserted it in "g-recaptcha-response" textarea tag
3) I place in my username + password
4) Call bestbuy ca's hidden callback function via javascript:

i.e.
___grecaptcha_cfg.clients['0']["$"]["$"]["callback"]("TOKEN_HERE")

The page returns an error after submit, and states that that something went wrong.
