Frequently Asked Questions

Email mismatch error when logging in with Google and others

Dymo API normalizes the email by default, removing, for example, the . and + from the email based on the specific provider, which means that if you are not also normalizing the email in the login via OAuth, you will get a mismatch error.

To do this, you have two options: the first and correct one would be to also normalize the login email, and the second would be to disable normalization using normalize: false.
