The squad, including former Chelsea striker Samuel Eto'o, refused to fly to South America on Sunday morning.
But they eventually agreed a financial package with the nation's football federation after an emergency meeting.
The squad will take off from Yaounde at 21:30 BST, 12 hours late, and should arrive in Brazil on Sunday evening.
Team coach Volker Finke had said players were complaining that the £61,000 they were due to be paid for figuring in the World Cup was not enough.
After agreeing an end to the row, Cameroon Football Federation president Joseph Owona said: "Everything has been resolved.
"We have opted for transparency. There is no problem and I think the team needs to be mobilised for all to look in one direction."
Cameroon are in Group A with the hosts, Croatia and Mexico.
