Businesses and customers with PayPal accounts can easily send and receive payments online without the need to turn to more traditional payment mechanisms. The total value of PayPal transactions in 2011 was $118 billion, generated by 110 million active registered accounts and owned by customers in 190 markets worldwide. PayPal mobile payment volume in 2011 was $4 billion, growing from $750 million in mobile payments in 2010. (Active accounts are those that have had activity in the past 12 months.) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.verifone.com/online-payments/advanced-payment-methods-apms/paypal.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
