We need to implement the Google ads conversion tags. And we did as mentioned below but where we can find the conversion Label, Value, currency code and Order ID.
Are you asking what values go into each of those items (Label, Value, Currency and Order ID)?
If so, that is for the people who are setting up the Conversion to tell you what they want....
Some generic advice:
Label should probably always be there, this is a text value that will give your conversion some contextual meaning (usually this corresponds to the action or success that has occurred)
The others are optional, but can provide additional context... we really can't help you determine those values....
See this Google support page for how to get the Conversion ID and Label from Google Ads' interface: https://support.google.com/tagmanager/answer/6105160?hl=en
You will need to provide your own currency code and order ID, since these would depend on your user's purchase.
