Tasks are the building block of Skyvern. They represent a single instruction to the browser to go do something using language models. Ex. “Go to alibaba and extract this information”

## Request - Initiate a task (Webhook)

| proxy_location | String | yes | RESIDENTIAL | Proxy location for the web-browsing request. Please pass RESIDENTIAL as a value |
