"invalid API key" on rest api calls

auser

This is my first time trying to use the API.

I login with https://api.smugmug.com/services/api/rest/1.2.2/?method=smugmug.login.withPassword&APIKey=...&EmailAddress=...&Password=...

and get a response with stat="ok" and a session id.

Then I try: https://api.smugmug.com/services/api/rest/1.2.2/?SessionID=...&method=smugmug.categories.get

and I get <rsp stat="fail"><method>smugmug.categories.get</method><err code="18" msg="invalid API key"/></rsp>

I tried a few different methods, always with the same result. What's wrong?

I got it to work. I used wget with "--save-cookies /tmp/cookies.txt --keep-session-cookies" for the login.withPassword, and "--load-cookies /tmp/cookies.txt" on the subsequent categories.get. Is the requirement of having cookies enabled documented anywhere?

Just wanted to say thanks for posting this. I was trying to use the API from perl, and was running into this error too. Your posts helped me along.

This is all I needed to do in perl to enable cookies:

use HTTP::Cookies;

my $cookie_jar = HTTP::Cookies->new(
    file => "sm_cookies.dat",
    autosave => 1,
  );

my $ua = LWP::UserAgent->new;
$ua->cookie_jar($cookie_jar);
