Only name is required. If a supplier with the same name and IBAN already exists in the organization, it is returned instead of creating a duplicate. If the IBAN already belongs to a supplier with a different name, the call fails with 422.
Sensitive fields (payment_details and tax_identifiers) are masked in the response unless the caller is allowed to see them.Authorizations
OAuthSecretKey
Bearer authorization header: Bearer <token>, where <token> is the access token received from the authorization server at the end of the OAuth 2.0 flow.
