Populate Lookup Field via Web API

(0) ShareShare

Posted on by JDMCRM 1,799

Hi, 

First time attempting to push data to Dynamics 365 programmatically via the Web API. I need a little help with populating lookup fields. 

If I have the GUID available this isn't an issue. The following POST creates a new lead with the Currency set to Euro. 

{
"subject" : "newlead3",
"transactioncurrencyid@odata.bind" : "/transactioncurrencies(2817303a-a84c-e811-8102-3863bb341bf8)"
}

How can I achieve this if I don't have the GUID available, and my source data only contains the string value EUR? I imagine I need to lookup the isocurrencycode from the associated transactioncurrency entity and when a match is found return the GUID for the matched Record. Is this correct?

    Yes, it is correct. You cannot set currency only by it's name. As you wrote you need to fetch the guid of it first.

    Hi Andreas, thanks for the response. Is there an example of how this can be achieved? I'm testing using Postman.

    /api/data/v8.2/transactioncurrencies?$select=currencyname,isocurrencycode&$filter=contains(currencyname,'Euro')

    Results in:

    {

     "@odata.context":"crm365.domain.dev/.../v8.2$metadata#transactioncurrencies(currencyname,isocurrencycode)","value":[

       {

         "@odata.etag":"W/\"361185\"","currencyname":"Euro","isocurrencycode":"EUR","transactioncurrencyid":"695a881a-7a4f-e811-910d-00155dd55305"

       }

     ]

    }

    which includes the required guid field
