PATCH Request Business Central Web Service

(0) ShareShare
ReportReport
Posted on by TESDEveloper 10

I am trying to perform a PATCH request in postman on a Business Central Cloud record. 

I have created the Web Service in Business Central, and published. I can perform a GET and view the record in postman.

I am trying to perform a PATCH to update any of the fields. The request looks like:

My request body is set as:

{
    "Code1": "Test"
}
The Primary Key of the "Outbound Transaction" is 12.
Please could anyone advise on anything I should be doing differently.
The page is a standard page, not an API page. 
Thank you.

    The issue has been resolved by adding the following to the headers:

    content-type: application/json;EEE754Compatible=true

    Our table has a Primary Key of ID which is an integer which seems to be the problem, and the need for the additional content-type.

    Thank you.

    Only difference I can see, is that I specify the customer no like this:

    Customer_Card(No='20000')

    While you do it like this:

    Customer_Card(20000)

    But I would suspect that this would give a different error message if that was not correct.

    Hi,

    I can't really see any problems there, so I tried it out here, also with Postman:

    PATCH api.businesscentral.dynamics.com/.../Customer_Card(No='20000')

    BODY

    {"Name": "Trey 2"}

    HEADERS

    Content-Type application/json

    If-Match *

    And this works fine. So to me it looks like you are doing everything correctly.

    My first idea was that you are missing the Content-Type header, but you are not.

    It's like maybe there is an invisible character in the Body? Try to re-type it (no copy and paste).

Under review
