BadRequest error returned posting customer via BC API

(0) ShareShare
ReportReport
Posted on by 20

I'm trying to create a customer with the following URL and data and receiving the followig error.

Error:

{"error":{"code":"BadRequest","message":"Invalid Request Body  CorrelationId:  6f64a809-4a74-4bbb-a2a7-73349b923dee."}}

Endpoint:

api.businesscentral.dynamics.com/.../customers

Data:

{
"number": "TEST1000",
"displayName": "Test Customer",
"type": "Company",
"addressLine1": "",
"addressLine2": "",
"city": "",
"state": "",
"country": "",
"postalCode": "",
"phoneNumber": "",
"email": "",
"website": "",
"salespersonCode": "",
"balanceDue": 0,
"creditLimit": 0,
"taxLiable": false,
"taxAreaId": <taxAreaId-guid>,
"taxAreaDisplayName": "",
"taxRegistrationNumber": "",
"currencyId": "00000000-0000-0000-0000-000000000000",
"currencyCode": "USD",
"paymentTermsId": <paymentTermsId-guid>,
"shipmentMethodId": "00000000-0000-0000-0000-000000000000",
"paymentMethodId": "00000000-0000-0000-0000-000000000000"
}

To get the data in my customer, I manually created one in the app, retrieved that data with the api and changed the number and displayName,

I also removed fields:       "@odata.etag",  "id", "blocked", and "lastModifiedDateTime"

Any help would be appreciated.

    "type": "Company",
    "addressLine1": "",
    "addressLine2": "",
    "city": "",
    "state": "",
    "country": "",
    "postalCode": "",
    "phoneNumber": "",
    "email": "",
    "website": "",
    "salespersonCode": "",
    "creditLimit": 0,
    "taxLiable": false,
    "taxRegistrationNumber": "",
    "currencyId": "00000000-0000-0000-0000-000000000000",
    "currencyCode": "USD",
    "shipmentMethodId": "00000000-0000-0000-0000-000000000000",
    "paymentMethodId": "00000000-0000-0000-0000-000000000000"
    }

    Getting the same error with that data. Perhaps I'm missing something else? What's in your request header?

    Are you using POST method and

    Same. I don't get it.

    Could it be that I have a permissions problem or perhaps don't have the setting correct for auto generating the id guid?

    I'm kind of at a loss.

    I didn't see the first part of that. Yes I'm using the POST method and have the Content-Type in my header.

    Can you try with GET method first? and check if you are getting the customer list.

  • Pat Arneson Profile Picture

    Yes, I've successfully gotten a customer list and queried on a specific number using a filter.

    URLs I'm using. These work fine as get requests.

    url = f"api.businesscentral.dynamics.com/.../customers"

    url = f"api.businesscentral.dynamics.com/.../customers eq '{customer_number}'"

    Here's my python code:

    import msal

    import logging

    import json

    import requests

    customer_id = 'removed'

    def acquire_token():

       config = json.load(open("parameters.json"))

       app = msal.ConfidentialClientApplication(

           config["client_id"], authority=config["authority"],

           client_credential=config["secret"],

       )

       result = None

       result = app.acquire_token_silent(config["scope"], account=None)

       if not result:

           logging.info("No suitable token exists in cache. Let's get a new one from AAD.")

           result = app.acquire_token_for_client(scopes=config["scope"])

       return result['access_token']

    class Customer:

       json = ""

       def __init__(self, json):

           self.json = json

           print(self.json)

       @staticmethod

       def get_customers():

           access_token = acquire_token()

           url = f"api.businesscentral.dynamics.com/.../customers"

           result = requests.get(

               url,

               headers={'Authorization': 'Bearer ' + access_token}, )

           print("gd: %s" % result)

           result_json = result.json()

           print("Graph API call result: ")

           print(json.dumps(result_json, indent=2))

       @staticmethod

       def query_customer(customer_number):

           access_token = acquire_token()

           url = f"api.businesscentral.dynamics.com/.../customers eq '{customer_number}'"

           result = requests.get(

               url,

               headers={'Authorization': 'Bearer ' + access_token}, )

           print("status: %s" % result.status_code)

           result_json = result.json()

           print("result data: ")

           print(json.dumps(result_json, indent=2))

       @classmethod

       def create_customer(cls):

           print(cls.json)

           access_token = acquire_token()

           url = f"api.businesscentral.dynamics.com/.../customers"

           result = requests.post(

               url,

               data=cls.json,

               headers={'Authorization': 'Bearer ' + access_token, 'Content-type': 'application/json',

                        'Content-Length': str(len(cls.json))}, )

           print("status: %s" % result.status_code)

           print("messsage: %s" % result.text)

    Customer.get_customers()

    Customer.query_customer("WHATEVAH")

    customer = Customer(open('test_customer.json').read())

    customer.create_customer()

    And the current contents of my data file:

    {

    "number": "TEST1000",

    "displayName": "Test Customer",

    "type": "Company",

    "addressLine1": "",

    "addressLine2": "",

    "city": "",

    "state": "",

    "country": "",

    "postalCode": "",

    "phoneNumber": "",

    "email": "",

    "website": "",

    "salespersonCode": "",

    "creditLimit": 0,

    "taxLiable": false,

    "taxRegistrationNumber": "",

    "currencyId": "00000000-0000-0000-0000-000000000000",

    "currencyCode": "USD",

    "shipmentMethodId": "00000000-0000-0000-0000-000000000000",

    "paymentMethodId": "00000000-0000-0000-0000-000000000000"

    }
