HI Stefan ,

thanks please reply!

a!localVariables(
  /*Check whether the request body contains a document*/
  local!success: not(isnull(http!request.body)),
  if(
    local!success,
    a!startProcess(
      processModel: cons!Base64ToPdfConversionPOC,
      processParameters: {
        /*A document*/
        Transcript: todocument(http!request.body),
        
      },
      /*If a document was uploaded, return a successful response*/
      onSuccess: a!httpResponse(
        statusCode: 200,
        headers: { },
        /*Print the document id, name, and extension of the uploaded document*/
        body: concat(
          "Upload Successful: ",
          document(http!request.body, "id"),
          " - ",
          document(http!request.body, "name"),
          ".",
          document(http!request.body, "extension")
        )
      )
    ),
    /*If no document was uploaded, return an error code*/
    a!httpResponse(
      statusCode: 400,
      headers: { },
      body: "400 Document Not Provided"
    )
  )

HI Stefan,

I have tried what mentioned in the link given above, I really need help in completing this ,I tried a POC it is accepting only binary format document not "application/json".

Can you help me with this scenario like accepting base 64 encoded string in "application/json" format and converting it into original doc format and saving in Appian.

the document will be send in an integration with SAP where Appian API is exposed and they are consuming our API.

If you are not finding a solution can Appian support help me with this scenario??This is really important requirement for our current integration with SAP!

Thanks

Hi Stefan ,

SAP will provide the input in base 64 format and can we use the same scenario as mentioned in the above link/documentation?

thanks

Sorry. And what about this? docs.appian.com/.../passing-a-web-api-document-into-a-process-model.html

Hi Vinay kumar is it deprecated that smart service in 20.4 version??

Can anyone from Appian answer me?

Since we are not able to find that smart service in a process model?

thanks

Hello Sunu Sam,

If you are specific to doing this in a process model, try to use smart service - Base64 to Appian document conversion...

Hope this helps

Hi Stefan,

we have API exposed for integration system like SAP to consume our APi and we have a process model connected to it, we do not have connected system /integration as mentioned in above link or document shared by Vinay_kumar_Putchala.

Our scenario is totally different , we need to implement the base 64 decoding to pdf in a process model.

if you have examples of same please share it with me? even documentation is fine

-thanks in advance for your reply.

Thanks

This is exactly what is talking about. Is there a reason this does not work for you?

Hi Vinay_Kumar,

Thanks please answer ,if anyone knows how to do?

Hello sunus0001,

The integration object allows you to receive Base64 documents and store them in Appian's file system: https://docs.appian.com/suite/help/21.3/Integration_Object.html#receiving-base64-inline-with-json

Hope this helps !!

Thanks
