Create multiple shortened URLs
Request
The date that the shortUrl will expire on. Expired URLs will redirect users to the URL not found page. We generally recommend you pick a expiration date that is twice as long as you expect the URL to be 'useful' for. See these examples. If you are generating one-off links (OTP, safe key, user specific American Express offer, etc.) which will be used in the next three days, then pick a expiration date of one week. Alternatively if you are generating links for a marketing campaign where the campaign is expected to finish one year from now, then give an expiration date of two years.
This is to request a specific "vanity" URL. If provided, we will try and register the link on this path. If the path is not available for the requested domain (i.e., it was already taken), the request will return an HTTP 400 error.
This is to provide information about the user submitting the DotAmex registration request; to be referenced for link expiration communication.
