Unlink Identifier

Unlinks an identifier from a Customer Journey, the supplied unlinkIdentifier will be unlinked from the rest of the provided identifiers. The updated state of identifiers will be returned in the response.
This can be used to unlink previously associated identifiers to improve the accuracy of any searches involving them.
Note: This does not delete the identifier, instead it simply "unlinks" it from any other associated identifiers. It can still be used as part of a search.
And this way unlinking identifier from Customer Journey will not affect AXP's Digital Workflow , its only internal to Customer Journey.
