FAQPage Schema
How do I initialize a PubNub client and publish a message across platforms?▼

Initialize a PubNub client by configuring your publish and subscribe keys, then use the SDK's publish method to send messages. Cross-platform setup supports JavaScript, Python, Swift, Kotlin, and Java for real-time messaging.

What's the best way to design channels for scalable PubNub publish/subscribe messaging?▼

Design scalable PubNub channels using structured naming patterns and listeners to route messages efficiently. Proper channel design prevents message congestion and ensures reliable publish/subscribe delivery across web and mobile apps.

Does PubNub work with both web and mobile SDKs for real-time messaging?▼

Yes, PubNub works with web and mobile SDKs including JavaScript, Python, Swift, Kotlin, and Java. Cross-platform SDK initialization allows you to implement real-time messaging and presence features consistently across different environments.

How do I handle errors and configure security for PubNub listeners?▼

Handle PubNub listener errors by implementing robust callback strategies and secure configuration. Configure authentication tokens and validate message payloads within your listeners to maintain secure real-time messaging workflows.

Why does my PubNub message listener drop messages on high-volume channels?▼

PubNub listeners may drop messages on high-volume channels due to inefficient channel design or missing error handling. Optimize publish/subscribe workflows by implementing proper message queueing and listener lifecycle management.
