williamclark 2025-05-15 09:24 reporter ~0017954	The problem occurs because PayPal has a hard restriction of 128 characters for item titles, and when we encode HTML entities like quotes (`"`) as that looks like (`"`), it counts as a character, and would exceed the 128 character limit despite the original string being under 128 characters. This causes a 400 Bad Request with INVALID_STRING_LENGTH error code. The solution is to truncate or sanitize item names prior to sending that to PayPal, and make sure that when we account for encoding, the total number of characters is still under the limit. Consider having your checkout integration either check before encoding, or auto-truncate or something similar.
