In Partner API using Graphql query - conversations, I am getting all the list of messages sent by merchant users.
Is there any query or mutation to update the reply to those messages through Graphql?
First, great question here and completely understandable why you would be looking for this type of feature!
Currently, the Shopify Partner API offers the ability to programatically access specific data from a partner account via GraphQL, opening the door to optional automation of various front and back end operations. However, this is limited to queries and doesn’t currently allow for mutations - a full overview of Partner API features can be found in this doc here.
Whilst not specifically related to the features you mention, there have been some changes and a recent update to the Partner API. Moving forward, I'd keep an eye on the Developer Changelog and also the Developer Blog - these are both excellent resources for tracking feature updates, news, or releases!
Thanks you for your reply. Will keep an on developer changelog and developer blog, at the same time please update me during availability of the feature I am looking for.
