(.NET Core C#) ITIDA Debug Signed JSON and HTTP POST

See more Egypt ITIDA Examples

Explains how to debug when problems are encountered with ITIDA canonicalization, signing, and posting to api.preprod.invoicing.eta.gov.eg.

The most common error response from the api.preprod.invoicing.eta.gov.eg server is:

ITIDA Signature Invalid Signature * 4043 4043:message-digest attribute value does not match the calculated value[message-digest attribute value does not match the calculated value]
