Is it / will it become possible to contribute data via python in the same way that one does it with RtContribute in excel?
Sorry, that link was to a closed discussion. I copied below the answer by Alex Putkov. from that discussion:
"To the best of my knowledge the only comprehensive contributions solution available in Eikon is RtContribute worksheet function in Eikon Excel.
The only API available in Eikon that currently provides contributions capability is AdxRtContribute object of legacy Eikon COM APIs. This object only provides contributions through TREP. In other words it cannot be used with Hosted or Refinitiv Managed Eikon accounts. It's possible to use AdxRtContribute object in Python, albeit only in 32-bit one. However this is rather cumbersome and it only works if the client has contributions infra setup on their TREP. Here's the link to an article describing how to use AdfinX Analytics COM library in Python. The same technique can be utilized to use AdxRtContribute object of AdfinX Real-Time library of Eikon COM APIs."
"From a technical perspective =RtContribute worksheet function in Eikon Excel and AdxRtContribute COM object of Eikon COM APIs are two distinct things with overlapping but not identical capabilities."
No. Because TRCC contribution is posted via propitiatory encrypted tunnel. See this article and diagram.
That can be provided by TREP, or Elektron SDKs (Java and C/C++) also have this capability.
It's better to post a new question as a separate new question, and refer to the relevant answered question via link, rather then adding it as answer, because new answers on answered questions with accepted answers tend to be overlooked by the community.
