Hi All,

We are using On-Prem Business central,

i want to create a custom API which will send item detail , sales price detail and item picture with picture URL or binary string. i tried but in the picture content we are receiving only the media link URL and i don't know i to use this media link to show data in my web page, actually another application consuming this api.

below is my code.

query 50112 GetCustomerWithOrder
{
    QueryType = API;
    APIPublisher = 'QueryV1';
    APIGroup = 'QueryGroup';
    EntityName = 'Item';
    EntitySetName = 'Items';
    elements
    {
        dataitem(ItemDetails; Item)
        {
            column(ItemNo; "No.")
            {
            }
            column(Name; Description)
            {
            }
            column(Inventory; Inventory)
            {
            }
            column(Picture; Picture)
            {
            }
            column(Base_Unit_Price; "Unit Price")
            {
            }
            dataitem(Pricelist; "Sales Price")
            {
                DataItemLink = "Item No." = ItemDetails."No.";
                SqlJoinType = LeftOuterJoin;
                column(Unit_Price; "Unit Price")
                {
                }
                dataitem(pictures; "Picture Entity")
                {
                    DataItemLink = Id = ItemDetails.Picture;
                    SqlJoinType = LeftOuterJoin;
                    column(PictureContent; Content)
                    {
                    }
                }
            }
        }
    }
    var
        myInt: Integer;
    trigger OnBeforeOpen()
    begin
    end;
}

Custom API for Item details with Pictures

Hello,

You need to convert pictures into base64 format in API and consuming application should convert it back from base64 to picture.

I would suggest you to use page API instead of query API.

Pictures are stored in Tenant Media record, so you need to get Tenant Media record for the picture. And content should be converted to Base64.

local procedure SetValuesFromMediaID(MediaID: Guid)

var

TenantMedia: Record "Tenant Media";

begin

// TODO: This code should be replaced once we get a proper platform support

// We should not build dependencies to TenantMedia table

if IsNullGuid(MediaID) then

exit;

TenantMedia.SetAutoCalcFields(Content);

if not TenantMedia.Get(MediaID) then

exit;

"Mime Type" := TenantMedia."Mime Type";

Width := TenantMedia.Width;

Height := TenantMedia.Height;

Content := TenantMedia.Content;

end;

I'm putting a sample code works for company information picture, you need to fit this to tenant media:

procedure GetCompanyLogoBase64(): Text

var

Base64: Codeunit "Base64 Convert";

Tempblob: Codeunit "Temp Blob";

OutS: OutStream;

InS: InStream;

Base64Txt: Text;

begin

rec.CalcFields(Picture);

if Picture.HasValue then begin

Tempblob.FromRecord(Rec, Rec.FieldNo(Picture));

Tempblob.CreateInStream(InS);

Base64Txt := Base64.ToBase64(InS);

exit(Base64Txt);

end;

end;

Custom API for Item details with Pictures

Hi, When you open this table directly, is there any data?

The normal practice is Picture (Item table) -> Content (table 2000000184 "Tenant Media")

Hope this helps.

Thanks.
