Do you want to ask S. Antonio for a favor? Here is the prayer to say!

So we can invoke Saint Anthony to ask him for a grace. A prayer must be recited invoking his intercession. It is obvious that if we anticipate prayer from a good confession and Holy Communion, the oratory dynamism becomes invincible. That is: there is no devil that stands between us and the sky!

Here is how we can invoke St. Anthony to ask him for a grace. A prayer must be recited invoking his intercession:
Admirable Saint Anthony, glorious for the fame of miracles and for Jesus' predilection, who came in the guise of a child to rest in your arms, obtain from him his goodness the grace that I ardently desire within my heart. You, so compassionate towards miserable sinners, do not pay attention to my demerits, but to the glory of God, who will once again be exalted by you and to my eternal salvation, not separated from the request that I am now soliciting.

(Say the grace in your heart)

May my charity pledge my gratitude to the needy with whom, through the grace of Jesus the Redeemer and through your intercession, I have given myself to enter the kingdom of heaven.

Amen.
