Tip

The unit_mismatch error code will be returned if the value for two or more units does not match within a single request.

This can occur in 3 key situations:

  • when the weight.unit value in multiple shipment_contents differs (e.g. one shipment_contents specifies kg and another specifies lb)
  • when the dimensions.unit value in multiple shipment_contents differs (e.g. one shipment_contents specifies cm and another specifies in)
  • when the currency value does not match across multiple shipment_contents (e.g. one shipment_contents specifies GBP and another specifies USD)
