# Machine Link Events

In a Machine Link project the script code is executed as events that happens during different phases of the project execution.

There two types of event - per telegram and global. The telegram events must be named with the telegram name post fixed. Ie. `PostParseMain_T1` where T1 is the telegram name.

The events are:

<table><thead><tr><th width="301">Name</th><th width="145" data-type="checkbox">Per telegram</th><th>Description</th></tr></thead><tbody><tr><td><a href="/pages/v27Sq6Lm0xsJH3OG56zO">Initialization</a></td><td>false</td><td>Called before anything else</td></tr><tr><td><a href="/pages/v27Sq6Lm0xsJH3OG56zO">Finalization</a></td><td>false</td><td>Called after the execution is complete</td></tr><tr><td><a href="/pages/02jIgnisUUrRgM3GYUIa">OnBeforeOptimization</a></td><td>false</td><td>Only on Optimization G2</td></tr><tr><td><a href="/pages/XoY2sQDap87WMmSvTBcp">PreParseMain</a></td><td>true</td><td></td></tr><tr><td><a href="/pages/l6ibcYrXVkIICsvNOav1">PostParseMain</a></td><td>true</td><td></td></tr><tr><td><a href="/pages/KtWnbyZUipDCi2ecLPR2">ParseChild</a></td><td>true</td><td></td></tr><tr><td><a href="/pages/k5ZoXwnc0py6Z48PALT3">BeforeOutput</a></td><td>true</td><td></td></tr></tbody></table>
