      summary: Look up whether a user is known to Trustly
      description: '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.'
