Hi @Sheik,
With Assume identity feature, public notes can be posted on behalf of the agents in the account with an admin’s API key.
But, it is not possible to post public notes on behalf of another admin/account admin with one admin’s API key. The original admin’s API key has to be used to post replied on behalf of them through the app.
Note: Assume identity feature is available from the Garden plan of Freshdesk only. Refer here [1] for all the available features based on the pricing plans.
