Financial Force REST API for Journals

Question

I'm trying to use the REST API for Journal creation in Financial Force. The path is

services/apexrest/c2g/v1.0/journals/*

I was able to login, and perform the call but I am receiving an error message

<Response [400]>

[{"message":"Unexpected parameter encountered during deserialization: Company at [line:1, column:17]","errorCode":"JSON_PARSER_ERROR"}]

The JSON I'm passing in the body is

{ 
    "Company": "ELIM Company-SEC",
    "Date": "2018-09-01",
    "Currency": "USD",
    "LineItems": [{
            "GeneralLedgerAccount": "181102 - Intermediate Holdings",
            "Value": -11114954.25,
            "LineDescription": "Journal"
        }]
    }

Has anyone used this call before? I'm wondering if there's some other key I have to supply in my JSON call prior to the actual journal entry. The documentation on their website doesn't give any indication that is the case though.

Update: I did try sending it as a list, wrapped in [ ] but it still errored, with this message

"Error message": "JSON request body must be an object at [line:1, column:2]", "errorCode": "JSON_PARSER_ERROR"

Answer 1

Looking at the documentation, it should be an array so your JSON should look like this:

[{ 
    "Company": "ELIM Company-SEC",
    "Date": "2018-09-01",
    "Currency": "USD",
    "LineItems": [{
            "GeneralLedgerAccount": "181102 - Intermediate Holdings",
            "Value": -11114954.25,
            "LineDescription": "Journal"
    }]
}]

I was able to use your XML to create a Journal in FFA, see screenshot of Workbench below (had to change company and GLA name to match my org):

You should have enabled the Accounting Journal API in the Feature Console first, can you confirm you have done that? If you are still having problems, it might be an idea to raise a support ticket with FinancialForce.

The documentation shows, albeit not very explicitly, that the JSON structure it's expecting is a list, not a map:

[{
    "Company": "Merlin Auto AUS",
    <snip>
}]

You need to wrap your map up in [] so it can be deserialized by the Apex on the receiving side.
