Configuration

Description

PNConfiguration instance is storage for user-provided information which describe further PubNub client behavior. Configuration instance contain additional set of properties which allow to perform precise PubNub client configuration.

Method(s)

To create configuration instance you can use the following function in the Unity V4 SDK:

  1. new PNConfiguration();
    PropertiesTypeRequiredDefaultsDescription
    SubscribeKeystringYesSubscribeKey from Admin Portal.
    PublishKeystringOptionalPublishKey from Admin Portal (only required if publishing).
    SecretKeystringOptionalSecretKey (only required for access operations, recommended to be used on secure servers due to security reasons ).
    CipherKeystringOptionalIf cipher is passed, all communications to/from PubNub will be encrypted.
    UUIDstringYesSDK generated uuidUUID to use. You should set a unique UUID to identify the user or the device that connects to PubNub.
    Allowing the SDK to generate a random UUID can result in significant billing impacts, particularly on an MAU pricing plan.
    LogVerbosityPNLogVerbosityOptionalPNLogVerbosity.NONESet PNLogVerbosity.BODY to enable debugging. To disable debugging use the option PNLogVerbosity.NONE
    AuthKeystringOptionalNot setIf Access Manager is utilized, client will use this authKey in all restricted requests.
    SecureboolOptionaltrueUse SSL.
    MessageQueueOverflowCountintOptional100When the limit is exceeded by the number of messages received in a single subscribe request, a status event PNRequestMessageCountExceededCategory is fired.
    SubscribeTimeoutintOptional310The subscribe request timeout.The value is in seconds.
    NonSubscribeTimeoutintOptional10For non subscribe operations (publish, herenow, etc), how long to wait to connect to PubNub before giving up with a connection timeout error.The value is in seconds.
    FilterExpressionstringOptionalNot setUsed to subscribe with a custom filter expression.
    HeartbeatNotificationOptionPNHeartbeatNotificationOptionsOptionalPNHeartbeatNotificationOptions.FAILURESHeartbeat notifications, by default, the SDK will alert on failed heartbeats (equivalent to: PNHeartbeatNotificationOptions.FAILURES).
    Other options such as all heartbeats (PNHeartbeatNotificationOptions.ALL) or no heartbeats (PNHeartbeatNotificationOptions.NONE) are supported.
    OriginstringOptionalCustom origin if needed.
    ReconnectionPolicyPNReconnectionPolicyOptionalPNReconnectionPolicy.NONESet to PNReconnectionPolicy.LINEAR for automatic reconnects. Use option PNReconnectionPolicy.NONE to disable automatic reconnects.Use option PNReconnectionPolicy.EXPONENTIAL to set exponential retry interval.
    PresenceTimeoutintOptional0Use to set custom presence server timeout.The value is in seconds.
    PresenceIntervalintOptional0Used to set custom interval to send the ping back to the server. This is automatically set to a recommended value when PresenceTimeout is set to a custom value.The value is in seconds.
    MaximumReconnectionRetriesintOptionalinfinitySets how many times to retry to reconnect before giving up.
    SuppressLeaveEventsboolOptionalWhen true the SDK doesn't send out the leave requests.

Basic Usage

Note

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

PNConfiguration pnConfiguration = new PNConfiguration();
// get subscribeKey from Admin Portal
pnConfiguration.SubscribeKey = "SubscribeKey";// required
// publishKey from Admin Portal (only required if publishing)
pnConfiguration.PublishKey = "PublishKey";
// secretKey (only required for access and history delete operations , keep away from Android/iOS)
pnConfiguration.SecretKey = "SecretKey";
// if cipherKey is passed, all communicatons to/from pubnub will be encrypted
pnConfiguration.CipherKey = "CipherKey";
// UUID to be used as a device identifier, a default UUID is generated
// if not passed
pnConfiguration.UUID = "PubNubUnityExample";
// Enable Debugging
pnConfiguration.LogVerbosity = PNLogVerbosity.BODY;
// if Access Manager is utilized, client will use this authKey in all restricted requests
pnConfiguration.AuthKey = "authKey";
// use SSL.
pnConfiguration.Secure = true;
// PSV2 feature to subscribe with a custom filter expression
pnConfiguration.FilterExpression = "such=wow";

// heartbeat notifications, by default, the SDK will alert on failed heartbeats.
// other options such as all heartbeats or no heartbeats are supported.
pnConfiguration.HeartbeatNotificationOption = PNHeartbeatNotificationOption.All
pnConfiguration.PresenceTimeout = 60;

pubnub = new PubNub(pnConfiguration);

Initialization

Include the code

Download the PubNub Unity package and import it to your Unity project by going to Assets -> Import Package -> Custom Package. Now that your PubNub Unity Package has been imported, you must enable it in the Test Runner. To enable the PubNub Unity Package, go to Window -> General -> Test Runner. Click on the mini drop down menu next to the window close button, and click Enable playmode tests for all assemblies. You will have to restart your Unity editor to finalize these changes. Congrats, you are now all setup to start using the PubNub Unity SDK! (OR if using the code from the source add files from PubNubUnity/Assets folder to the Assets folder of your project.)

using PubNubAPI;

Description

This function is used for initializing the PubNub Client API context. This function must be called before attempting to utilize any API functionality in order to establish account level credentials such as PublishKey and SubscribeKey.

Method(s)

To Initialize PubNub you can use the following method(s) in the Unity V4 SDK:

  1. new PubNub(pnConfiguration);
    ParameterTypeRequiredDescription
    pnConfigurationPNConfigurationYesGoto Configuration for more details.

Basic Usage

Initialize the PubNub client API:

Note

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.SubscribeKey = "my_subkey";
pnConfiguration.PublishKey = "my_pubkey";
pnConfiguration.Secure = true;
pnConfiguration.UUID = "myUniqueUUID";
pubnub = new PubNub(pnConfiguration);

Returns

It returns the PubNub instance for invoking PubNub APIs like Publish(), Subscribe(), History(), HereNow(), etc.

Other Examples

  1. Initialize a non-secure client:

    Note

    Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

    PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.SubscribeKey = "my_subkey";
pnConfiguration.PublishKey = "my_pubkey";
pnConfiguration.Secure = true;
pnConfiguration.UUID = "myUniqueUUID";
pubnub = new PubNub(pnConfiguration);

  2. Initialization for a Read-Only client:

    In the case where a client will only read messages and never publish to a channel, you can simply omit the PublishKey when initializing the client:

    Note

    Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

    PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.SubscribeKey = "my_subkey";

pubnub = new PubNub(pnConfiguration);

  3. Use a custom UUID

    Set a custom UUID to identify your users.

    Note

    Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

    PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.SubscribeKey = "mySubscribeKey";
pnConfiguration.PublishKey = "myPublishKey";
pnConfiguration.Secure = true;
pnConfiguration.UUID = "myUniqueUUID";

pubnub = new PubNub(pnConfiguration);

  4. Initializing with SSL Enabled:

    This examples demonstrates how to enable PubNub Transport Layer Encryption with SSL. Just initialize the client with Secure set to true. The hard work is done, now the PubNub API takes care of the rest. Just subscribe and publish as usual and you are good to go.

    Note

    Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

    PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.SubscribeKey = "my_subkey";
pnConfiguration.PublishKey = "my_pubkey";
pnConfiguration.Secure = true;
pnConfiguration.UUID = "myUniqueUUID";
pubnub = new PubNub(pnConfiguration);

  5. Initializing with Access Manager: Requires Access Manager add-onRequires that the Access Manager add-on is enabled for your key. See this page on enabling add-on features on your keys:
    https://support.pubnub.com/hc/en-us/articles/360051974791-How-do-I-enable-add-on-features-for-my-keys-

    Note

    Anyone with the SecretKey can grant and revoke permissions to your app. Never let your SecretKey be discovered, and to only exchange it / deliver it securely. Only use the SecretKey on secure server-side platforms.

    When you init with SecretKey, you get root permissions for the Access Manager. With this feature you don't have to grant access to your servers to access channel data. The servers get all access on all channels.

    For applications that will administer PAM permissions, the API is initialized with the SecretKey as in the following example:

    Note

    Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

    PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.SubscribeKey = "my_subkey";
pnConfiguration.PublishKey = "my_pubkey";
pnConfiguration.SecretKey = "my_secretkey";
pnConfiguration.UUID = "myUniqueUUID";
pnConfiguration.Secure = true;

pubnub = new PubNub(pnConfiguration);

    Now that the pubnub object is instantiated the client will be able to access the PAM functions. The pubnub object will use the SecretKey to sign all PAM messages to the PubNub Network.

Event Listeners

Description

You can be notified of connectivity status, message and presence notifications via the listeners.

Listeners should be added before calling the method.

Adding Listeners

pubnub.SubscribeCallback += SubscribeCallbackHandler;

//Handler
void SubscribeCallbackHandler(object sender, EventArgs e) {
    SubscribeEventEventArgs mea = e as SubscribeEventEventArgs;

    if (mea.Status != null) {
        switch (mea.Status.Category) {

Listener status events

CategoryDescription
PNNetworkIssuesCategoryA subscribe event experienced connection issues when running.
PNReconnectedCategorySDK was able to reconnect to pubnub.
PNConnectedCategorySDK subscribed with a new mix of channels (fired every time the channel / channel group mix changed).
PNAcknowledgmentCategoryUsed API reported success with this status category.
PNAccessDeniedCategoryRequest failed because of access error (active PAM). status.AffectedChannels or status.AffectedChannelGroups contain list of channels and/or groups to which user with specified auth key doesn't have access.
PNTimeoutCategoryUsed API didn't receive a response from server in time.
PNDisconnectedCategoryClient unsubscribed from specified real-time data channels.
PNUnexpectedDisconnectCategorySubscribe loop failed and at this moment client is disconnected from real-time data channels. This could due to the machine or device is not connected to Internet or this has been lost, your ISP (Internet Service Provider) is having to troubles or perhaps or the SDK is behind of a proxy.
PNBadRequestCategoryRequest cannot be completed as not all required values have been passed (like subscribe key, publish key) or passed values are of unexpected data type.
PNMalformedFilterExpressionCategorySubscription request cannot be processed as the passed filter expression is malformed and cannot be evaluated.
PNMalformedResponseCategoryRequest received in response non-JSON data. It can be because of an error message from the proxy server (if applicable).
PNDecryptionErrorCategoryHistory API may return this status category in case if some messages can't be decrypted.
PNTLSConnectionFailedCategoryTLS handshake issues. In most cases is because of poor network quality and packets loss and delays.
PNRequestMessageCountExceededCategoryThis status event will be fired each time the client receives more messages than the value of RequestMessageCountThreshold, set in PNConfiguration.
PNReconnectionAttemptsExhaustedIn case of network disconnect the PubNub client SDK will attempt to reconnect a finite number of times after which this status is sent and the re-connection attempts will stop.
PNUnknownCategoryPubNub SDK returns this error for SDK exceptions or when server responds with an error.

UUID

Description

These functions are used to set/get a user ID on the fly.

Method(s)

To set/get UUID you can use the following method(s) in Unity V4 SDK:

  1. UUID
    PropertyTypeRequiredDescription
    UUIDstringYesUuid to be used as a device identifier, a default Uuid is generated if not passed.
     
  2. pnConfiguration.UUID;

    A property in the PNConfiguration class.

Basic Usage

Set UUID:

Note

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.UUID = "myUniqueUUID";
pubnub = new PubNub(pnConfiguration);

Get UUID: 

string UUID = pnConfiguration.UUID;

Authentication Key

Description

Setter and getter for users auth key.

Method(s)

  1. AuthKey
    ParameterTypeRequiredDescription
    AuthKeystringYesIf Access Manager is utilized, client will use this AuthKey in all restricted requests.
     
  2. pnConfiguration.AuthKey;

    A property in the PNConfiguration class.

Basic Usage

Set Auth Key 

PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.AuthKey = "authKey";
pubnub = new PubNub(pnConfiguration);

Get Auth Key 

string AuthKey = pnConfiguration.AuthKey;

Returns

Get Auth key returns the current authentication key.

Filter Expression

Requires Stream Controller add-on Requires that the Stream Controller add-on is enabled for your key. See this page on enabling add-on features on your keys:
https://support.pubnub.com/hc/en-us/articles/360051974791-How-do-I-enable-add-on-features-for-my-keys-

Description

Stream filtering allows a subscriber to apply a filter to only receive messages that satisfy the conditions of the filter. The message filter is set by the subscribing client(s) but it is applied on the server side thus preventing unwanted messages (those that do not meet the conditions of the filter) from reaching the subscriber.

To set/get filters you can use the following property. To learn more about filtering, refer to the Publish Messages documentation.

Property(s)

  1. FilterExpression
    PropertyTypeRequiredDescription
    FilterExpressionstringYesPSV2 feature to Subscribe with a custom filter expression.
     
  2. pnConfiguration.FilterExpression;

    A property in the PNConfiguration class.

Basic Usage

Set Filter Expression

Note

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

PNConfiguration pnConfiguration = new PNConfiguration();
pnConfiguration.FilterExpression = "such=wow";
