@Todd
Thank you for the quick response!

I walked through this Stack Overflow thread and was able to authenticate my Function App using my B2C user, I'll post the details from the link below.

Steps:

1- Create an Azure Functions App and write down the URL i.e. https://jatrantest.azurewebsites.net
2- Within your AzureAD B2C tenant:

• Configure your application in Azure Active Directory B2C and copy the ApplicationID (ClientID).
• Within your App -> Select "Authentication" -> Add a "Web" platform Redirect URI -> adding the suffix /.auth/login/aad/callback For example - https://jatrantest.azurewebsites.net/.auth/login/aad/callback

-Navigate to your AzureAD B2C User Flows -> Select your sign-in flow -> Select "Run user Flow" -> Copy the metadata endpoint URL

3- Within your Function App:
-Select Authentication / Authorization on the left blade -> Turn on "App Service Authentication" -> Select Azure Active Directory -> Select "Advanced"

Client ID - This is the Application ID of your B2C application  
Issuer Url - This is the metadata endpoint URL  
Client Secret - This is optional, however, you can create a secret within your B2C app and paste it here.  

-Select "OK" -> Select Save

4- To test out functionality in your B2C tenant
-Select the Sign-in Flow -> Select "Run user Flow" -> Select the Reply URL you added earlier (/.auth/login/aad/callback) -> Run user flow

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
