Using the API

When you recieve your response from Linden Lab stating that you have been accepted into the Registration API program, follow the steps described in How to set up your Reg API.


If you are using the Reg API to sign up registrants on the main grid, users under 18 will not be allowed to register, since they are not permitted on the Main Grid. Therefore, when testing, use a birth date that makes the registrant older than 18 years.

Use an email address that does not currently exist in Second Life. If a user has already registered with an email address, the Reg API will return "error 95, email exists." If you trap errors, you will see this error code, but if not, registration will simply fail.
