@NeeharikaSh, Utilizing a custom action to transmit the payload encompassing 5 profiles within an audience will result in the recognition of 5 distinct payloads. For instance, upon the execution of a custom action that retrieves the profile information from the audience, an API call will be initiated to the designated endpoint for dispatching the details of profile1 such as the firstname, lastname, and other relevant data fields and so on. In the scenario where the audience comprises 10000 profiles, a total of 10000 API calls will be generated to post the data accordingly.
