2Captcha

How to use 2Captcha in a web scraping pipeline

2Captcha can supply a solution for a supported challenge encountered by your collection client. It occupies one step within an existing HTTP or browser workflow; it does not discover URLs, render the target application or extract the records you need.

A practical workflow

1. Let your collector identify the challenge and capture the task parameters required for that supported type, including the relevant page context.
2. Submit a task through the solving API and obtain its result through the documented result or callback flow. Keep the task ID with the collection attempt.
3. Return the solution to the original client, complete the appropriate interaction, and then run your normal response validation and extraction.

When it fits

Use this integration when a known challenge is an occasional, identifiable interruption in an otherwise functioning collector. Track solver failures separately from parser failures so that a rejected solution does not look like an empty dataset.

Boundaries

A solution is not a universal access token. Challenge type, session context and the receiving client must agree. Bound retries and wait time, and do not assume that a successful API task means the target accepted the interaction or returned useful content.
