Hello,
I am new to Business Central and need some help using the API. I am trying to retrieve the following fields on the Customer table (with the intention to update them) using the API.
- Salesperson Code
- Training Certificate Date
- Training Completed

However, when I use Postman to call the API I do not see these fields in the response returned:

I am using an HTTP GET to call into the API: api.businesscentral.dynamics.com/.../<<guid>>/sandbox/api/v1.0/companies(<<guid>>)/customers?$filter=number eq '54321'
What am I missing here? How do I call the API to access these fields for a single Customer record? Any help is greatly appreciated.
Thanks,
John
