Call IEC interface from ION API and get response

Hello,

I have a scenario on single where a 3rd party is calling ION API and that ION API is just sending HTTP request for a HTTPSyncIn channel on MEC and this channel is the input channel for an interface to retrieve some data form M3 and responds back to the HTTP request with this data in the response body. I need to implement same scenario on multi-tenant but in MT we don't have the concept of calling the communication channel. How to do implement a scenario where ION API can call the IEC interface and get the response on the same call?

Thanks

In MT every "product" has more limitations / restrictions to Developer Team.

Maybe You can use IEC interface for that but the code inside it will be more restricted...

any Idea what is the replacement of the HTTPSyncIn channel ION?

antonio-caria

You use it inside ION Desk?

Simply the scenario is 3rd party will call ION API >> this ION API will call IEC Interface >> the interface responds back to the ION API >> the ION API responds to the 3rd party

Hi @mohamed-elsharkawy

One of the solutions that I can think of is using MNS260 API (MBM initiator).

Call API MNS260/AddMBMInit - Creates a temp entry in MNS260.
- Create a Media control object in CRS945/CRS949 and this need to be passed in the API PRF1, PRF2
- PRTF field is for the Print file where it can help for detection in event rules.
- MKV4, MKV5, MKV6, MKV7 Message key values can be used to send information that can be used in the IEC mapper for M3 data extraction.
- returns BMIN that needs to be used in PrcMBMInit

Call API MNS260/PrcMBMInit - pass the BMIN that will trigger the event to the event hub

Create an Event analytics rule for the print file mentioned in the ION API and redirect it to the IEC mapper and create Sync out BOD transfer it over to the ION DESK and call ION API of the third party service with BOD data.

We do have some other approaches that may be using IMS. But the above one is simple solution.

Nice description, but does this solution really solves the scenario described to get the response on the same call?

No, it doesn't, the one I mentioned is an async solution. Then I realized it should be HTTP request and response, so I messaged Mo.A.sh use the XtendM3 to create a transaction and add the mapper logic in XtendM3 code which can be directly invoked by Third-party application via ion api.

Maybe you can try creating a document flow in ION desk that calls the ION API and get the response in an XML file/BOD that can trigger the IEC interface. The IEC mapping can output an XML file/BOD that can be adjusted as needed using xslt mapping to be used as an input for the ION API call once more.

Hello,

If you want a synchronous response, call ION API from your 3rd party apps and retrieve API response in a JSON format.

What is the value of going through IEC ? Do you modify strings ? Do you do mathematical operations on numeric fields before sending response ? Can you give us more details of the purpose of this IEC mapping ?

Hello,

The reason of using IEC mapping is that it's already implemented this way on the single tenant. but now we as per @sudhakaran-samadurai advice, we may include the logic of the mapping in XtendM3 API and use it through ION API

Simple, don't use EC (MEC).

MT MEC will not solve Your problem.

Sync calls should be in XtendM3 - Even in ST the asyn call is not very reliable
