Questions tagged [paypal]

For questions about the PayPal API used by software developers to process payments, manage invoices, monitor accounts, etc. (For user-level support, contact PayPal directly using their site.)

PayPal is a commerce business allowing payments and money transfers to be made through the internet, mobile and point of sales.

PayPal has a large set of APIs currently available to the public, a full list of which is available at the Classic API References and Rest API References

PayPal provides Open-Source SDKs that can be used to make calls to both Classic and REST APIs. The SDKs for REST APIs are actively developed, and maintained in github repositories

Further developer resources are available at PayPal Developer as well as a full overview of all PayPal API error codes at API Errors

PayPal technical support for PayPal APIs (as well as Website Payments Standard) is available via PayPal Technical Services at https://www.paypal-techsupport.com

Ask questions if you are a software developer only. If you are a PayPal user, contact Paypal using their customer support.
