signal-cli-rest-api/plugins/migrate-v1-plugin-to-v2.md

Migrating a plugin from version 1 to version 2 is really easy.

• Change your plugin definition (*.def) file and set the version to 2 e.g:

endpoint: my-custom-send-endpoint/:number 
method: POST
version: 2

• Change your plugin script and implement the exec (and optionally the init) functions.

e.g:

function exec()
    -- your plugin code goes here
end 

function init()
    -- if your script needs some additional setup (e.g a sqlite database, a config file, etc)
    -- the initialization can be done here.
end
