thank you for your reply thez asked me to upload the receipt of payment online im relay got confused i did it through my mobile but no where to uploadYou have few ways to pay as stated here: https://www.canada.ca/en/immigration-refugees-citizenship/campaigns/biometrics/how-to-give-biometrics.html. I would recommend that you pay at the VAC centre, if you belong to one based on your residence. If not then you can pay (or your husband ) online , and there should he instructions how to submit at this point in your process. It is always better to do it at the same time as the application fee. Good luck.
Edit: checked the link and this may work better: http://www.cic.gc.ca/english/information/fees/index.asp
I just entered random country and it gave me explanation that you may pay online then print the receipt and bring it with you to the vac center when u go for bio
