Tasks

Legacy Task APIs

The core building block in Skyvern

DEPRECATION ALERT: the APIs in this page are being deprecated. Last supported date: Jan 1, 2026. Please use the Run Task API and migrated to the new API.

Tasks are the building block of Skyvern. They represent a single instruction (goal) to the browser to go do something using language models. Ex. “Search for Skyvern on googgle.com and summarize the information about Skyvern.”
