Good morning,

Or I think it's not possible to be done or there is something I don't know. I need to create a new record in BC using Postman, I can't use anything else. I have the following JSON:

{

"value":[

{

"Transaction_ID": "9000",

"Prod_Order_No": "TEST-EMS1",

"Line_No": 10000,

"Operation_No": "10",

"Item_No": "08692",

"Quantity": "100",

"Work_Center_No": "P1",

"Standard_Task_Code": "",

"Sales_Order_No": "ODV20-0030",

"Sales_Order_Line_No": 10000,

"Creation_Date": "2020-06-04T00:00:00",

"Imported": true,

"Error": ""

}

]

}

that I put on body request. Request method is a POST, I insert right URL, authentication is NTLM with username and password, content-type application/json

Nothing: always error 400, if I change authentication, I'll receive error 401

Is it possible I miss something. I'm using postman. If I do a get it's ok, this is a json I find doing a get

Best regards

RE: Post a JSON from Postman to Nav BC

Hello,

The value you have, is an array. A simple set of fields will work, for example:

Insert a new customer:

POST {{BaseUri}}/companies(85410dc0-d3e8-ea11-bb97-000d3a492d5b)/customers

HEADER:

Content-Type = application/json

BODY (Raw):

{ "number": "10010", "displayName": "Test AS", "phoneNumber": "911 123", "email": "Contact@contoso.com" }

That should return:

Provided of course that authentication is OK - to check that, see if a simple GET {{BaseUri}}/companies(85410dc0-d3e8-ea11-bb97-000d3a492d5b)/customers works OK.

Thanks you for you reply. Now I show you what I do. I think that NTLM is the root cause. Get function works properly, Post function gives error 400

So I say it's a post method, with an url https://:

I deleted society name but address is given to me by technicians

Then I inserted authorization:

Username and password are sent to me by technicians. If I change authorization, I'll receive error 401

Then I add the following header: application/json for content-type

Then I add the body:

always the same error. I think NTLM is not supported as I read from web, because GET operation is running properly

Best regards

I assume that you have enabled NTLM as well in NST settings?

As, per default it is not enabled.

Authentication works the same way for read and write, so I suspect more there is a typo somewhere. How about if you try antother API for example "customers" and the example I sent?

I need to explain you something. As I think you understand, I don't manage Nav BC, but I need to connect from Filemaker to it by webservice. THere is one thing also to say: NTLM authentication is not supported by Filemaker, for which I need to use in curl options --anyauth. This authorization doesn't give me any issues with GET operations, while Post gives me them. If I try using .Net, doing a development I think ic C#, there are no issues. Also Fiddler gives me problems

Perhaps trying a different authentication is worthwhile. I typically use the web service method which is with basic authentication. You will need a web service key applying to the user account. For a POST I would typically add into the header If-Match *

RE: Post a JSON from Postman to Nav BC

I experimented today a little with JSon arrays sent from BC - first using Azure functions in C# and JavaScript, but then I found out that I have Apache with PHP configured on my laptop, and tried the same with json_decode.

Fullscreen

A variation of the classics - "Hello World", but with a list of names in the body of the POST request.

And the data I used is a slightly simplified version of your message: a json object containing an array of objects:

Fullscreen

And it works without any problems, no matter if I send content as application/json or text/plain. Looks like there is some conversion happening on the server side before the request body is passed to json_decode.
