Absolutely. Group DMs use a significantly different model to the previous format, so for a start it is there is effort required to document and describe. Secondly, we haven’t done any work around anticipating additional load and capacity needs driven from other clients on those endpoints. Thirdly, opening up any new API endpoints can sometimes lead to unforeseen behaviours if they are called in unexpected ways, which we’d need to more thoroughly test and account for. Finally, as I mentioned previously, we need to prioritise; the majority of what you will have seen around changes to the developer platform in the past year has been focused on Fabric, and embedded timelines and Tweets - so we can’t just “flip a switch” to open up an endpoint, much as it might seem that way.
I totally appreciate that this is disappointing if this is a feature you’re looking for, but I’m not currently aware of a timeline for enabling this.
The existing DM APIs have not changed and will continue to work for one-to-one DM conversations.
