is correct, but there’s another meaning for Latin based languages:

In the Romance languages, such as Italian, Portuguese, Spanish and French, the phrase “quid pro quo” is used with the original Latin meaning, referring to a misunderstanding or a mistake ("to take one thing for another").

In those languages, the Latin phrase corresponding to the English usage of “quid pro quo” is “do ut des” ("I give so that you will give").

It roughly means "Something given for something received".
A modern equivalent is "You scratch my back and I'll scratch yours"

It means I google the answer to your question, and you then do a favor for me.
