The African team refused to get on its plane to Brazil until the issue was resolved, and eventually began its journey 12 hours later than scheduled.
The Cameroon Football Federation (CFF) has confirmed it had to take out a private loan to meet players' World Cup bonus demands.
Cameroon's squad refused to board a plane to Brazil on Sunday until the issue was resolved, and eventually left for the tournament 12 hours later than scheduled.
CFF spokesperson Laurence Fotso said the governing body was forced to secure a private loan against future World Cup payments.
"Everything is OK now," Fotso said. "That money is given [by FIFA] three months after the end of the competition, so we borrowed money as a private loan to satisfy the players."
Cameroon coach Volker Finke had played down the situation prior to the team's departure, suggesting the row was "not really as big as people made it out to be".
He told Sport1: "There has been an agreement now, and there is no need to make a big sensation out of it or make huge stories out of it."
Neither the bonus dispute, nor the absence of talismanic striker Samuel Eto'o, affected Cameroon in its final warm-up match in Yaounde on Saturday as it beat Moldova 1-0.
Finke's men begin their World Cup campaign with a game against Mexico on Friday.
