PayPal SOAP API Basics

CorrelationID for Reporting Problems to PayPal

The value returned in CorrelationID is important for PayPal to determine the precise cause

of any error you might encounter. If you have to troubleshoot a problem with your requests,

we suggest that you capture the value of CorrelationID so you can report it to PayPal.

UTF-8 Character Encoding

The PayPal API assumes that all data in requests is in Unicode, specifically, the Unicode (or

UCS) Transformation Format, 8-bit encoding form (UTF-8).

In responses, the API always returns data in UTF-8.

Date/Time Formats

The PayPal SOAP API schema defines date/time values as Coordinated Universal Time

(UTC/GMT), using ISO 8601 format, and of type ns:dateTime. An example date/time

stamp is 2006-08-24T05:38:48Z

Core Currency Amount Data Type

The core currency amount data type is called BasicAmountType and is derived from

string. All currency amount fields have the following structure:

1. The currencyID attribute is required.

2. The amount must have two decimal places.

3. The decimal separator must be a period (“.”).

4. You must not use any thousands separator.

5. BasicAmountType has a data type of ebl:CurrencyCodeType, which defines a large

number of different currency codes. However, for your processing to succeed, you must set

currencyCode to a valid currency code. Some APIs support only a subset of currencies.

Here is an example. (The field name Amount is an example; actual field names can vary

depending on the specific API.)
