Add a constraint
On the Digital ID, the document the user adds last will default to be the source of the attributes shared. If you wish to ensure your attributes have come from a specific source please follow the below instructions:
- Log on to the Yoti Hub
- Head over to your application and scenario.
- Go to the bottom and you will see advanced settings:
Application > Scenario > Advanced settings
- Click advanced policy editor.
- Find the attributes you want with a source constraint and add an anchor source. See below for an example with a full name and date of birth.
{ constraints: [ { type: 'SOURCE', preferred_sources: { anchors: [ { name: 'PASSPORT', sub_type: '' } ], soft_preference: false } } ], name: 'date_of_birth', anchors: [], derivation: '', optional: false, accept_self_asserted: false, alternative_names: [] }, { constraints: [ { type: 'SOURCE', preferred_sources: { anchors: [ { name: 'PASSPORT', sub_type: '' } ], soft_preference: false } } ], name: 'full_name', anchors: [], derivation: '', optional: false, accept_self_asserted: false, alternative_names: [] }Was this page helpful?
