Is there a way to programmatically create users for testing with Azure AD B2C? The only way to create users that I am aware of is through website signup. Am I missing something?
Yes, Azure AD B2C Graph API allows CRUD operations on users.
You can create a user by sending a "POST" request to the /users endpoint.
The following documentation demonstrates this with a "B2CGraphClient" utils written in C# : Azure AD B2C: Use the Graph (see GitHub link in the page to download the sample code)
Please note there are two types of user account in Azure AD B2C : "local accounts" and "work or school accounts". Required parameters vary upon the account type you need.
