Message Actions API for Unity SDK

Add or remove actions on published messages to build features like receipts, reactions, or to associate custom metadata to messages. Clients can subscribe to a channel to receive message actions events on that channel. They can also fetch past message actions from Message Persistence independently or when they fetch original messages.

Message Actions vs. Message Reactions

Message Actions is the flexible, low-level API for adding any metadata to messages (read receipts, delivery confirmations, custom data), while Message Reactions specifically refers to using Message Actions for emoji/social reactions.

In PubNub Core and Chat SDKs, the same underlying Message Actions API is referred to as Message Reactions when used for emoji reactions - it's the same functionality, just different terminology depending on the use case.

Remove Message Reaction

Requires Message Persistence

This method requires that Message Persistence is enabled for your key in the Admin Portal.

Remove a previously added action on a published message. Returns an empty response.

Method(s)

To Remove a Message Action you can use the following method(s) in the Unity SDK:

pubnub.RemoveMessageAction()
    .Channel(string)
    .MessageTimetoken(long)
    .ActionTimetoken(long)
    .Uuid(string)
    .Execute(System.Action<PNRemoveMessageActionResult, PNStatus>)

* required

Parameter	Description
Channel * Type: string	Specifies channel name to publish message actions to.
MessageTimetoken * Type: long	Publish timetoken of the original message
ActionTimetoken * Type: long	Publish timetoken of the message action to be removed.
Uuid * Type: string	UUID of the message.
Execute * Type: System.Action	System.Action of type PNRemoveMessageActionResult.
ExecuteAsync Type: None	Returns Task<PNResult<PNRemoveMessageActionResult>>.

Sample code

Returns

Get Message Reactions

Requires Message Persistence

This method requires that Message Persistence is enabled for your key in the Admin Portal.

Get a list of message actions in a channel. Returns a list of actions sorted by the action's timetoken in ascending order.

Truncated response

Number of message actions in the response may be truncated when internal limits are hit. If the response is truncated, a more property will be returned with additional parameters. Send iterative calls to Message Persistence adjusting the parameters to fetch more message actions.

Method(s)

To Get Message Actions you can use the following method(s) in the Unity SDK:

pubnub.GetMessageActions()
    .Channel(string)
    .Start(long)
    .End(long)
    .Limit(int)
    .Execute(System.Action<PNGetMessageActionsResult, PNStatus>)

* required

Parameter	Description
Channel * Type: string Default: n/a	The channel name.
Start Type: long Default: n/a	Message Action timetoken denoting the start of the range requested (return values will be greater than or equal to start).
End Type: long Default: n/a	Message Action timetoken denoting the end of the range requested (return values will be less than end).
Limit Type: int Default: 100	Specifies the number of actions to return in response. Default/Maximum is 100.
Execute * Type: System.Action Default: n/a	System.Action of type PNGetMessageActionsResult.
ExecuteAsync Type: None Default: n/a	Returns Task<PNResult<PNGetMessageActionsResult>>.
