Cameroon claimed the 10th and final place in Africa's final qualifying round for the 2014 World Cup
The Indomitable Lions beat Libya 1-0 in a winner-takes-all showdown in Yaounde on Sunday.
They went into the match knowing a draw would be good enough thanks to Togo's use of a suspended player - Alexis Romao - when the two teams met in June.
Aurelien Chedjou headed home the only goal of the match in the first half.
Chedjou scored three minutes before the break and the victory saw Cameroon clinch top place in Group I with 13 points from their six matches.
Libya finished four points behind after arriving in Yaounde needing to win the match to secure a place in the final round of qualifiers.
The Indomitable Lions remain on course to extend their World Cup finals appearances to seven at Brazil 2014.
Other group winners to qualify for the two-legged play-offs are Algeria, Burkina Faso, Cape Verde, Egypt, Ethiopia, Ghana, Ivory Coast, Nigeria and Senegal.
The draw will take place in Cairo on 16 September.
It will be based on the latest Fifa rankings to be released on Thursday and will create five two-leg ties, with the winners going to the finals in Brazil.
The decisive games will be played in October and November.
