After checking all available APIs available here https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/, it was identified the need for a new one to create Vendor Bank Account through an API.

It's possible to create/update/get a Vendor using https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/resources/dynamics_vendor with the basic fields but not possible to include Vendor Bank Account details.

A new API should be created to turn possible to create/update and get Vendor Bank Account Details (Table 288).

It will is also important to guarantee this new API is linked with Vendor API to allow the ability to use the expand function.
