PayShield's transaction processing (also known as "TxProcess") facilitates the online processing of Credit Card, Bank Transfer, wallet and many other payment options, while supporting the many different Transaction Types associated with the payment method.\
\
PayShield's transaction processing uses the 3 main different transaction workflows / lifecycles for an online transaction.  <br>

The combination of the different transaction types, payment methods and workflows makes PayShield's transaction processing able to handle any payment integration. Currently PayShield's transaction processing has over 400 integrations to different payment processors around the globe.\
\
PayShield's transaction processing can facilitate the Authorization transaction (the transaction collecting payment) for 3D Secure transactions.\
\
Along with supporting 3D Secure Authorizations, PayShield's transaction processing has the ability for rule based processing to limit exposure to fraud, and adhere to limits enforced by payment processors, to help maintain good merchant relationships with the processor.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.payshield.ai/transaction-processing/overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
