Yes, Tally.ERP9 can integrate with a Web Application by using XML Collection.
Following are the steps to achieve the same:
1. Invoke a User Defined Function Func1 to Integrate Tally.ERP9 with Web Application.
Example:
[Function: Func1]
2. Within the Function, walk over a Collection (XML Collection) XMLColl1 which, in turn sends XML request to the Web Application through a Report.
Example:
[Function: Func1]
00 : WALK COLLECTION : XMLCOLL1
[Collection: XMLColl1]
Remote URL : "
https://101.202.303.404/download.do
"
Remote Request : ReportConstRequestXML1 : ASCII
XML Object Path : TALLYMESSAGE:1:ENVELOPE:BODY:1
;; Path specified through XMLObjectPath is the Object path specification to the Response XML
3. Design a Report ReportConstRequestXML1 to construct the suitable XML request as agreed upon and understood by the Web Application.
Example:
[Report: ReportConstRequestXML1]
;; The above report must construct the agreed XML Request Format as understood by the Web Application
4. Once, the response is back, process the response within the Function Func1.
Example:
[Function: Func1]
00 : WALK COLLECTION : XMLCOLL1
10 : NEW OBJECT : Ledger
20 : SET VALUE : Name : $XMLName
30 : SET VALUE : Parent : $XMLParent
40 : END WALK
You may also want to develop a foolproof handshake mechanism to integrate masters and transactions where the same set of masters or transactions are not resent. This can be done by way of maintaining flag at either ends and setting the flag value as per the status.
Also, multiple requests can be sent as an acknowledgement of the previous transactions received, etc. similarly.
