I was taken the way, accident without visible scahden, procedure?

Hello, I was taken the way yesterday and it came to a slight collision. My car (10J old Fiesta has no visible damage. I also meant it has not come to any damage and he still wanted to report it to his insurance because it has comprehensive and carried lighter scratches on the car from it. Well today I received a call from his insurance company and I thought I should give it to a workshop and me an estimate for the damage read She also wanted to recommend me a workshop or evaluator? but refused. On the one hand, I don’t want to worry about it, because I have a lot to do right now, but I don’t know what it looks like under the bodywork. What do you say? Can I just have a look at the workshop and me? Thank you
