We use synchronous Realtime integration method in our examples. If you would like to use Proxy Endpoint or asynchronous Push-Pull integration, refer to the integration methods section.

Optionally, you can include additional parameters such as user_agent_type, render e mais para personalizar sua solicitação de scraping. Leia mais:
