Look up whether a user is known to Trustly

Checks whether a user has previously used Trustly, based on one or more provided identifiers (email or phone).

Merchants can use this endpoint without having to launch Trustly widget/lightbox. One such use case could be to use this endpoint early in the payment funnel — before the user reaches the payment selection screen — to determine whether to surface Trustly as the top payment option. A true response indicates the user is already familiar with Pay by Bank and is more likely to complete a Trustly-powered transaction.

How it works: The lookup queries Trustly's user database across all stored identifiers. If any provided identifier matches a known Trustly user, isInTrustlyNetwork is returned as true.

Authentication: Requests must be authenticated with HTTP Basic Auth using your accessId as the username and accessKey as the password.
