If the auto action is set to trigger on Completed, Processed and also Pending, will it mean that it will fire twice or maybe three times ?
Yes.
One for the first pending state and the second time for the Completed state for instance ?
Correct.
and if yes how can we avoid this to get only ONE outside invoice ?
I recommend whatever you're using to generate your invoices check if the invoice already exists or not before creating it.
For instance setting first payment to 180 € and recurring ones to 144 € and using the OnCpayAfterPaymentStatusUpdate sends only 144 as payment_gross or mc_gross to our API for invoicing with the attached code.
Those will always be the amount the basket paid. You can grab the recurring amount from mc_amount3.
Does it mean that this is not the correct trigger to use ?
That event fires anytime the payment state changes for a basket. I'm guessing it's the one you need to use, but there's also onCPayUserStateChange for when a users subscription state changes. onCPayUserStateChange however doesn't come with the basket object and only has the subscription object.
