Use the jsScenario parameter to simulate user interactions on the page before scraping. This enables you to handle dynamic pages that require clicking, waiting, or filling inputs to reveal content. The value of jsScenario is an array of steps, executed sequentially. Each step is an object that defines a single action (e.g. click, scroll, wait, fill).

​
Supported Actions

  • click – Click an element using a CSS selector
  • wait – Pause for a specific time (in milliseconds)
  • waitFor – Wait until an element appears in the DOM
  • waitForAndClick – Wait for an element and click it
  • evaluate – Run custom JavaScript in the page context
  • scrollX, scrollY – Scroll to a horizontal or vertical offset
  • fill – Input values into fields using selectors
All actions are executed in order, one after another

​
Example: Load More and Scroll

[
  { "click": "#loadMoreBtn" },
  { "wait": 1500 },
  { "scrollY": 2000 }
]
This sequence clicks a button, waits and then scrolls the page.

​
Example: Fill and Submit a Form

[
  { "fill": ["#email", "user@example.com"] },
  { "click": "#submit" },
  { "waitFor": ".confirmation" }
]
This fills an email field, clicks the submit button, and waits for a confirmation message.

​
Example: Evaluate Custom JS

[
  { "evaluate": "document.body.style.background = 'red'" }
]
This runs arbitrary JavaScript in the browser context before scraping.

​
Notes

  • If an element is not found (e.g. click or waitFor), the request will fail
  • jsRendering must be set to true for jsScenario to work
  • Use wait conservatively - prefer waitFor to avoid unnecessary delays
