Dear @Raseem

Kindly install the last version of the SDk.

Also, the hash should be calculated on the final version of the XML document after it has been signed. If you’re generating the hash before signing, the XML will change when signed, leading to a mismatch.

Kindly ensure you are correctly using the hash from the signed XML, not the unsigned version, The order should be:

  1. Generate the XML document.
  2. Sign the XML.
  3. Calculate the hash from the signed XML.
  4. Send the signed XML and the corresponding hash to the API.

If the issue still occurs, reach out with our support team via below emails:
