Why did I get API error code 81002?

PayPal returned API error code 81002 - Method Specified is not Supported.

PayPal identified your provided method as "unspecified" because it detected coding errors.

Debug your code. Replace or correct any invalid or deprecated variables.

Possible solutions:
  • Do not use urlencode + http_build_query, because this will result in double encoding.
  • Check that you aren't using a semicolon (;) as a separator. PayPal supports use of only ampersands (&) as separators. 
  • Review your code to ensure that none of the variables in it have been deprecated.
For help resolving this issue or others, visit PayPal's Contact Customer Service page.

Note: See the Developer Portal for a complete list of NVP/SOAP API error codes.
