These are defined in the Plaid docs, and explained here in more detail:
- NO DATA is returned when Plaid is unable to find an external data source to compare against the provided input data. This can happen for a variety of reasons, such as: an identity record that matches the provided data not existing (i.e. fraud), the input being very incorrect, little data existing for the provided identity (e.g. recently moved to the US, under 18), etc.
- NO MATCH is returned when Plaid is able to find an external data source(s) to compare against the provided data, but we’re not able to find a match for one or some of the provided data attributes (name, address, phone number, etc.) in the external data source(s).
