### Customization and trust of email domains via PingID SDK APIs

|   | As part of this feature upgrade, email template IDs have changed. Template locales are modified so that every occurrence of an underscore ("\_") character is replaced with a hyphen ("-").To reduce confusion, the creation of unusable or invalid templates is no longer allowed. Some invalid templates have been deleted. This includes:- Templates that don't contain the required `${otp}` parameter, either in the subject or in the email body.

- Templates that are missing "from" or "reply-to" addresses, or have an invalid address. |
