Global Data
Use global data to define a global variable within your workflow. For example, you have multiple new tab blocks wherein the URL input has the same domain e.g. "http://dribbble.com". Instead of editing the block one by one to change the URL domain, you can define the URL domain in the global data like:
json
{
"url": "https://dribbble.com"
}
And access the global data inside the URL text field of the New Tab block using an expression. For example, {{globalData.url}}
