**I will share all the information below step by step and with code i am using Please check :** 1- i have completed sandbox CSID and Compliance invoices successfully 2- i moved to fatoora Simulation environment and generated CSR , got successful response then i decoded binarysecurity token to use as X509 certificate Link that generated CSR : [https://gw-fatoora.zatca.gov.sa/e-invoicing/simulation/compliance](https://gw-fatoora.zatca.gov.sa/e-invoicing/simulation/compliance) 3- After generating CSR , i used binarysecurity : security as authorization and submitted all 6 types invoice ( standard , debit , credit | simplified , debit and credit ) . In every invoice i got successful message. Link i submitted all invoices : [https://gw-fatoora.zatca.gov.sa/e-invoicing/simulation/compliance/invoices](https://gw-fatoora.zatca.gov.sa/e-invoicing/simulation/compliance/invoices) 4- **in the last step i am getting an error** : i wanted to generate PCSID as per forum and document so used my “compliance\_request\_id” that generated in simulation CSID and used same authorization that generated in step 2. Link to generate PCSID : [https://gw-fatoora.zatca.gov.sa/e-invoicing/simulation/production/csids](https://gw-fatoora.zatca.gov.sa/e-invoicing/simulation/production/csids) * * * below i am attaching that generate my CSR , please check what am i doing wrong My CSR generating code to test in Google Collab : [click here](https://colab.research.google.com/drive/1SC_hotS3fDVQwITlUXna8VqTfM0NAMrq?usp=sharing) to check my CSR generation code in file : [click here](https://we.tl/t-UK4keq1K1L) ---

You may need to check what request you submitted to `/production/csid`. This endpoint has 2 actions **POST** and **PATCH** , make sure you send a POST Request to get the PCSID. ---

Hi, We are facing a similar issue with a client of ours for simulation onboarding. Were you able to find a solution/workaround for this? ---

Hi @idaoud , Thank you for your response, we will attempt to re-onboard the client in simulation next week and let you know. FYI though, this issue was seen only in the simulation the same client was onboarded successfully in production.
