I'm trying to verify my CSR for Visa checkout so I can promote my project, but I haven't had any luck. Been using openssl and filling in the necessary info, however, when using Visa's CSR UID I keep getting an "invalid CSR UID" message. If anybody's done this, please help 😄

Thanks for posting your question to the Visa Community Forum. If you are currently in Sandbox then the UID is not needed in the CSR while the project is in Sandbox.
To generate/create a CSR, please follow the getting started guide https://developer.visa.com/vdpguide#get-started-overview. The instructions provided on how to generate/create a CSR file is in chronological order. Please follow the getting started guide and on the left navigation guide, select Two-Way SSL (Mutual Authentication) https://developer.visa.com/vdpguide#twoway_ssl_mutual_authentication. This guide will walk you through on how to auto generate the CSR or create your CSR.
Please let me know if you have other questions.

Please refer the documentation Diana has advised in her reply.
Also make sure following is the format of your openssl command when generating the CSR file.
You have to include all the parameters, subject details in to the single line command.
Also please note that there is "-PROD" as a suffix to UID value.
Openssl req -new -key C:\TestPrivateKey.pem -out C: \TestCSR.pem -subj "/emailAddress=ProjectOwnerEmail@domain.com/UID=yourProjectUIDValue-PROD/CN=Your-FQDN/O=YourOrg/OU=YourOU/C=SG/ST=YourState/L=YourCity" -config "C:\temp\openssl.cnf"
I am using OpenSSL on Windows 10. I downloaded and installed OpenSSL-Win64 (OpenSSL Light). However, I don't have an openssl.cnf file. Did your install include the file or did you create the file?
You can create a config file for your own using a template that can be searched and downloaded from the internet.
And you can explicitly specify the path to it in your openssl command.
Thanks for the quick response to my last question.
Do you get this error
11892:error:2406F079:random number generator:RAND_load_file:Cannot open file:crypto\rand\randfile.c:88:Filename=./.rnd
And can it be ignored? I found a post on the openssl github site that indicates it isn't necessary and recommends removing RANDFILE= from openssl.cnf.
No need to reply to my previous post.
I created an openssl.cfg by copying an example I found. It doesn't include a RANDFILE= line
I ran this command to create a private key and the csr and there were no errors.
openssl req -new -keyout PrivateKey.pem -out Request.csr -subj "/emailAddressemail@example.com/UID=xxxxxxx-8950-49ba-bd12-5f07b67961b5-CERT/CN=www.myjob.com/O=My Company LLC/OU=Payments/C=US/ST=MyState/L=MyCity" -config "openssl.cnf"
For those who are curious, I found this sample config file and used it without edit
