Third-party integrations
Functions enables you to write code, or leverage existing code, to achieve required business logic, whether transforming messages and data as they pass through PubNub, re-routing those messages, augmenting, filtering, and even aggregating data for subsequent use.
Functions doesn't require you to spin up your own servers or incur increased latency through call-outs to external server/serverless technology; the code you write or leverage runs within PubNub's operational environment, giving you the scale and speed that you need for your applications.
Use Cases
With Functions, you can execute a variety of operations against your messages and data. You can also develop custom APIs that can be called directly from your own applications, services or processes. Some examples include:
User blocking discards messages from specific users.
Spam filtering detects spam messages and trashes them before they're sent to other users or recorded in history.
Aggregation logic combines multiple messages into a single message to subscribing clients. For example, in large chat rooms, it can be more efficient to aggregate reactions or live poll results.
Third-party integrations let you redirect message data to third-party services via web service calls.
Integration Catalog
PubNub develops and maintains this catalog with a large collection of predefined and customizable Functions. You can import Integrations from within the PubNub Admin Portal itself. You can quickly integrate to third-party services to do things like translate message content, integrate into a chatbot, or perform sentiment analysis on chat room content.
When you integrate with third-party services, such as Amazon, Librato, MapBox, or RingCentral, the services often require account setup to use them.
