What should a recruitment company do if it wants a payment code?

Don't give. The recruitment company asked for the payment code, but didn't give it to them. Don't just send the payment code on your mobile phone to anyone, whether it's WeChat or Alipay. Only when the merchant says "I'll scan you" when paying in a physical store can you open the payment code for the merchant to scan. Payment codes are used to collect money, so the recruitment company refused to give them.
