Before you begin

  • WooCommerce system requirements

  • Basic integration requirements from Unzer

  • To avoid rounding errors when submitting floating point numbers to the API, we recommend that you set the following value in your php.ini, which selects an improved algorithm for rounding such numbers.

    // php.ini
      ; When floats & doubles are serialized store serialize_precision significant
      ; digits after the floating point. The default value ensures that when floats
      ; are decoded with unserialize, the data will remain the same.
      serialize_precision = -1
