Having the Marriage blessed- help!!

Hi girls! So I was married in May and we had our wedding outside, so its not currently recognized by the Catholic church. We have to do our ceremony again (so fun!) but I'm not as on top of things this time. The priest said we needed to get a special marriage license, but I can't remember the name of it and he's out of town for the next week. Has anyone done this or can point me in the right direction???

Thank you!!!!
