How can I scrape data from complex multi-page forms?
I use Selenium to simulate form submissions page by page, ensuring each page is fully loaded before moving to the next. It’s slow but effective for complex forms.

Capturing and storing form data as I go allows me to pick up where I left off if the script stops unexpectedly. This is crucial for long, multi-page forms.

Sometimes, inspecting the network activity shows specific API endpoints that handle form data. Directly submitting to these endpoints can be quicker.

Automating form filling with tools like Playwright can speed up the process, especially if each page has predictable elements.

Adding delays between form submissions is essential to avoid detection, especially if the site monitors activity.

For forms with required fields, I validate the input data beforehand to prevent submission errors. This minimizes issues during scraping.

Checking for CSRF tokens is important, as many multi-page forms use them for security. I include these tokens in each request to maintain sessions.

If possible, I simulate real user actions, like waiting for page transitions, to avoid detection on heavily monitored sites.
