Dropbox api: Can someone provide a HTTP request example?

Could someone show me an example or a starting 开发者_运维百科point on how Dropbox api http requests should look?

For example if I want to receive tokens how would the HTTP/1.1 request look like for this? I'm planning on writing a program in C using sockets,

write(sockfd,buffer,strlen(buffer)); 

What should buffer look like to receive security tokens from dropbox? I hope I'm making sense.
