Adding contact to 'company' contact via API

(1) ShareShare
ReportReport
Posted on by IH-07071528-0 35
Hello,
 
We create customers (company type) via the standard API interface.
I am trying to add a contact for that customer also by API.
It seems I can only do that if I specify the company number (although looks like a contact no.) of the previously auto created contact. ie. "companyNumber = CT000076" in the contact create code.
 
My issue is how do I retrieve that CT number so I can create a new contact? Its not exposed by the customer endpoint and the contacts API cannot be searched by customer number or ID.

    Hi, If this field is not included in the standard API, it needs to be customized.
    Dynamics 365 Business Central: Can we extend standard APIs? – Download Standard Source Code for APIs
     
    In addition, regarding automatically created contacts, you can actually set the system to not create them automatically.

    Hope this helps.
    Thanks.

    Hi
    What our colleague Yun indicated is correct, if you want to customize or add functionality to an API you must customize it. Here I leave you some other interesting links, in addition to the link where you find the code for the standard APIs.

    Hello.
    Thanks for all your help. Now all sorted.
    For future searchers:
     
    1) Create a custom API to expose Contact Business Relation Table (5054).
    2) After creating a new customer. (Contact is auto created in our setup) use that API to return the 'Contact No' field where the 'No.' field is the customer number of the just created  customer. There will only be one as only just created customer.
    3) Create a new contact (type person) and fill the 'No.' field with the just returned value above.
    Not fully tested or error trapped yet but the basic method seems to work.
     
    Loving this software, incredibly well thought out and structured.
