I see on My Refinitiv the latest documentation resource for ADS REST access, if you visit MyRefinitiv -> ADS it contains
"Refinitiv Real-Time Distribution System 3.5 Online Documentation Library" which is an online resource that is designed to be searchable.
REST access documentation is part of ADS Installation Manual.
I note that you are on 3.4, however, please observe that 3.5 REST interface does not include per user Item Database requests, so the same would apply to 3.4 ADS.
Hope this helps.
This forum is intended to help developers with the usage of Refinitiv APIs included under API Catalog of Developers Portal.
For more in-depth help on TREP infra administration, as a customer, you may need to involve Refinitiv Helpdesk Online.
I see messages as "Output threshold breached for user" in the ADH log. Does that mean that the TREP Feed Handler is slow in consuming data from ADH or is this between ADS and ADH or the client that is requesting data?
