Is type and maximum size of Facebook’s application identifier defined somewhere? What column type and constraints should be used to store it in SQL database? Text/varchar most probably but what maximum length? Is it digit only?
I can of course suspect that it will be not longer than let’s say 32 digits/characters but I would like to be sure.
I have the same question regarding the application secret string. Is it possibly defined somewhere that it is 32 hex digits or I must assume it and possibly add some extra characters to be sure?
