Hi! Let me help you with this.

What do you mean by re-validate exactly?
Is the card requires_action?

[opal temple]

means, if a card is added yesterday, when it was valid, if a consumer tries to make a transaction today, in between if the card was blocked, how do we check again today if the card is still valid?

You can try charging it and if it fails you will ask them for another.

[opal temple]

so in our scenario, it's a post service transaction

which means, once we validate your card, we dispense gas. Once you're done, we deduct payment from your card

so payment collection is happening in background using Invoice

Yes.
