Dear @api_pioneers

Thanks for reaching out, Welcome to our community.

To provide comprehensive support as usual, can I kindly ask you to elaborate with the below:

1. What is the SDK version that you are using?

2. What are the exact steps (In details) that you are doing during the signing process for your B2C invoices?

Additionally, Kindly be informed that sandbox environment is just to clarify the onboarding steps, the onboarding process considered as successful only on Simulation or Production Environments.

Thanks,  
Ibrahem Daoud.

Dear @api_pioneers

Thanks for your elaboration.

Kindly be informed that the latest version of SDK is 3.4.5 you can find the installation link below, However, our recommendation is to install the latest version and try it again.

SDK link: [Zatca](https://sandbox.zatca.gov.sa/downloadSDK).

Thanks,
