Allowed Scopes: supplier:read

Retrieves a single supplier by its ID. Supplier data is cached for up to 24 hours; supplier account data (used for accountPayable) is cached for up to 20 minutes. Changes made through the API are returned by subsequent reads; changes made in Spendesk can take up to 24 hours to appear.

Pass include=externalIds to embed the IDs this supplier has in external systems (ERPs). It is opt-in because it costs an additional lookup.
