Linden Lab Official:Registration API Reference

To gain the capability URL for each service, POST your Second Life "first_name", "last_name", and "password" to https://cap.secondlife.com/get_reg_capabilities.

For more information on capability URLs, see Using capability URLs.

GET operations

get_last_names

The get_last_names operation retrieves the last names and corresponding IDs with which you are able to register new users.

Example GET Response:

<llsd> 
  <map> 
      <key>1926</key><string>Morellet</string> 
      <key>1683</key><string>Okamoto</string> 
      <key>1738</key><string>Rankin</string> 
... 
      <key>1870</key><string>Yang</string> 
  </map> 
</llsd>

get_error_codes

The get_error_codes operation returns an LLSD document describing the Reg API error codes. This information is reproduced in Registration API Error Codes.

The errors are in an array, and each error is, in addition, contained in an array. The first element in the array is the error code, the second is the name of the error, the third is the description.

Example GET response:

<llsd> 
   <array> 
       <array> 
           <integer>10</integer> 
           <string>invalid flow</string> 
           <string>The registration flow does not exist</string> 
       </array> 
       <array> 
           <integer>20</integer> 
           <string>missing required field</string> 
           <string>You are missing one of the required fields</string> 
       </array> 
... 
       <array> 
           <integer>1500</integer> 
           <string>malformed xml</string> 
           <string>Your xml is malformed</string> 
       </array> 
   </array> 
</llsd>

POST operations

create_user

The create_user operation creates a new Second Life Resident (user) account. POST to this URL a LLSD document, containing at least the following parameters:

username
last_name_id
email
dob
password

In addition, you can include any of the optional parameters listed in the table below.

If successful, the Reg API will return a hash containing the new user's agent_id. If there are errors, the Reg API will instead return an array containing the applicable error codes will be returned.

POST Parameters

Setting	Data type	Description	Default Value
username	String	Desired user name (Second Life first name). Must be between 2-31 alphanumeric characters. Certain first names are restricted; for example, those considered obscene or inappropriate for public use.	Required parameter.

email	String	User's email address.	Required parameter.
password	String	Desired password. Between 6-16 characters.	Required parameter.
dob	String	User's date of birth in the YYYY-MM-DD format. Users under 18 cannot be registered to the mainland. See limited_to_estate.	Required parameter.
limited_to_estate	Integer	ID of estate that the user will be limited to. To change this to another estate, you must own the estate. Optional parameter.	Estate 1, the mainland.
start_region_name	String	Region where user will initially appear after login. This can only be set to simulators in the user's limited to estate. Optional parameter.	Orientation island of the estate.
start_local_x	Float	X coordinate of the starting region. Must be between 0-256. Value must have two decimal places, for example: 123.00. Optional parameter; valid only when start_region_name is set.	128 (center).
start_local_y	Float	Y coordinate of the starting region. Must be between 0-256. Value must have two decimal places, for example: 123.00. Optional parameter; valid only when start_region_name is set.	128 (center).
start_local_z	Float	Z coordinate of the starting region. Must be between 0-256. Value must have two decimal places, for example: 123.00. Optional parameter; valid only when start_region_name is set.	128 (center).
start_look_at_x	Float	X component of the unit vector representing initial look direction. Must be between 0-1. Optional parameter; valid only when start_region_name is set.	0
start_look_at_y	Float	Y component of the unit vector representing initial look direction. Must be between 0-1. Optional parameter; valid only when start_region_name is set.	1

NOTE: You can get the numeric estate ID via the debug menus (Ctrl+Alt+Shift+D to enable them). Then use Client > View Admin Options. This will allow you to view, but not use, the options that admins (Lindens) can use. Now go to the Server menu, which appeared with the Client one. Select God Tools, look at the Region tab... the Estate ID is listed there. Don't worry about pressing or changing something you shouldn't... as they are just viewable options, any changes you make won't stick.

Return Value

Map - If user creation is successful, a map with the new user's information is returned

key: agent_id
- value (Integer): ID of new SL user.

or

Array - If user creation fails, an array of error code(s) is returned.
- Integer - Represents an error code (see get error codes)

check_name

The check_name operation checks to see if a user can be registered with a given Second Life first name and last name.

POST the new user's desired "username" and "last_name_id", and you'll get back LLSD XML, representing a boolean. The same parameter restrictions for the "create user" service apply here.
