We are working on integrating our software with Okta, and have run into an issue with the primary email that we generate for logins.
Logins are unable to use a real login, for various reasons. Our primary email follows the format _ username_@pd. customerName. During testing, emails such as firstname.lastname@example.org work great, but rfoster123@pd.SonetoDevelopmentTenant fails on user creation through the API. The error message is login: Username must be in the form of an email address .
How are email addresses validated in the API? Is there a maximum length for the final segment of the domain that we should take into account when constructing the email addresses in a format we can use effectively?
