Hi @c57b236c-2492-4379-94dc-2cc0ebb02b27
To contribute data to a RIC you need to use the Posting functionality provided by RFA Java API.
In order to post to a Chain RIC, you should first obtain an understanding of how Chains work / are implemented. You can get a good overview of the Chain implementation from the Introductory section of the Simple Chain Object Article. Whilst the article is targeted at EMA developers, part 1 of the Article is not really API specific.
Once you have an understanding of Chain structure etc, you can then refer to the StarterConsumer_Post example which is included within the RFA Java API examples sub folder (com.reuters.rfa.example.omm.postingConsumer). This should demonstrate how to perform a Post to a RIC. This knowledge combined with an understanding of Chain implementation should allow you to contribute data to a Chain RIC.
If you require help with any specific elements of the above, please post back with any further questions.
You can download the full latest RFA Java API package from the downloads section.
