Need help in converting Base64 encode string to PDF in an API exposed from APPIAN to SAP as input parameter

HI Appian team,

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 !!

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 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

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

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

Sunu Sam

Not sure. I would give it a try.

Hi Stefan,

I will also try the same and let you know the end results.

Thanks

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
