Getting Started

What is the Snapshot API?

Email snapshot of user interface

The Second Life Snapshot API enables you to parse information from Snapshot emails sent from Second Life for:

  • Blogging
  • Social Networking
  • Image Libraries

Where is the Snapshot API used?

There are many websites that already use this information. Some of them are as follows:



Email messages have headers that provide metadata about the message itself. Most of this information is hidden from the person reading an email message. You can use some of this information to verify that the snapshot came from a Linden Lab server.

The following headers are available.

Parameter Data type Description
X-Originating-IP string IP of simulator. []
Subject string Subject of message
Sender string email address of www-data account on simulator. "www-data" <www-data@sim8938.agni.lindenlab.com>
From string Combination of address and name. Note: name is not always avatar name.
Date date Date of snapshot in Pacific timezone.


Snapshots are sent as two parts. The first is plain text, and the second is a multi-part message in MIME format.

  • text/plain
  • multipart/related
    • text/html
    • image/jpeg - secondlife-postcard.jpg
    • image/jpeg - logo_secondlife.jpg


The HTML content within the multi-part message will contain details of the snapshot in a comment tag:

username="Dedric Mauriac"
Parameter Data type Description
agent_id key The UUID of the avatar that sent the message.
username string Quoted name of the avatar who sent the message.
region_id key The UUID of the region that the avatar was standing when the snapshot was taken.
sim_name string Quoted name of the region that the avatar was standing when the snapshot was taken.
global_x integer The grids horizontal location of where the avatar was standing when the snapshot was taken.
global_y integer The grids vertical location of where the avatar was standing when the snapshot was taken.
local_x integer The regions horizontal location of where the avatar was standing when the snapshot was taken.
local_y integer The regions vertical location of where the avatar was standing when the snapshot was taken.


Although you could use the entire HTML source code of a message, it is often not wanted. The original message contains additional information that is not needed. The message that the end-user wrote in the postcard itself is identified with comments:

test message

HTML Entities will be encoded. "<" will appear as "&lt;".

Referral Bonus

Snapshots include a URL to invite others to join them. If a new account is created from following the link, and certain conditions are met, then the sender could receive a bonus. This URL is wrapped around the logo in the message.



The snapshot is a JPEG image. Postcards have two images, including a logo. The snapshot file name is always called "secondlife-postcard.jpg".

Advanced Snapshot Tips

There are a few tweaks that you can do in order to get the most out of taking snapshots within the Second Life client. Here are a few.

Multiple Addresses

The Recipient email field can accept multiple email addresses. You can separate each one with a semicolon.


Populated Addresses

For those who always send snapshots to the same email addresses, you can edit a file on your file system to populate that information for you.

C:\Program Files (x86)\SecondLife\skins\default\xui\en-us\floater_postcard.xml

Look for the following and add your email addresses:

<text bottom="-35" follows="top|left" font="SansSerif" left="12" name="to_label">
    Recipient's Email:
<line_editor bottom_delta="-6" follows="left|top" height="20" 
left="120" max_length="254" name="to_form"
width="150" >account1@yourdomain.com;account2@yourdomain.com;account3@yourdomain.com</line_editor>

Longer Messages

By default, the message is limited to 700 characters. You can extend this to 6,526 characters by editing a file on your file system.

C:\Program Files (x86)\SecondLife\skins\default\xui\en-us\floater_postcard.xml

Look for the following and change the max_length property:

<text bottom_delta="-23" follows="top|left" font="SansSerif" left="12" name="msg_label">
<text_editor bottom_delta="-150" follows="left|top|right|bottom" height="140" left="12"
max_length="700" name="msg_form" width="420">
    Type your message here.
