Add users to Woocommerce without email

Question

I am using Woocommerce for a store. A plugin makes a request at this url

https://domain.ca/wc-api/v3/customers?...

And then receive an error:

ConstraintError: Unable to add key to index 'email': at least one key does not satisfy the uniqueness requirements.

I would like to know how I could bypass this error message. In other words, how could I modify Wordpress so that the email field is not required by Woocommerce?

Answer 1

You cannot have more than one user with the same email address by default in WordPress. You should try this plug-in which claims to override that functionality:

Allow Multiple Accounts
