Signature troubleshooting

From SafeCreativeWiki

Jump to: navigation, search

If you receive InvalidSignature errors, you can use the signature-analysis debug component to analyze the request and see how the server is calculating the required signature.

Simply add the parameter debug-component=signature.analysis to your API call. Do not include the debug-component parameter in your signature calculations.

NOTE: This component is only available in arena environment

This component returns the following XML structure:

  • signatureanalisys
    • requestCharacterEncoding: Character encoding as received in the request headers. Should be UTF-8
    • signatureWanted: Correct signature calculated by the API server for the provided parameters
    • signatureProvided: Signature provided on the request by the API client
    • tokens: Tokens used for building the string whose SHA-1 hash will be used as signature
      • string: Each of the tokens. Field names, values and separators are all treated in a different own line
        • order: Order of the token in the resulting string
        • value: Token text (XML-encoded, & really means the & character.
        • hexvalue: Token bytes using UTF-8 encoding. Value is presented as a string of hexadecimal digits 0-9a-f, two digits per byte.

Your private key is not shown and its hexvalue is presented as 00000000000, though the correct value is used for calculating the wanted signature.
