Why did I get API error code 10215?
PayPal returned API error code 10215 - Soft Descriptor truncated.
Cause
The Soft Descriptor you passed in your API request has been truncated. This informational error won't cause an API request to fail, but rather results in a Success with Warning.
Solution
To avoid this API error, send in a smaller soft descriptor. You'll find a detailed description of the SOFTDESCRIPTOR field in the Dynamic Soft Descriptors in Direct Payment section of the PayPal Developer Portal.
