Construct channel callbacks and test integrations locally.
A local callback simulator for developers. Built-in templates, saved events and scripts support protocol testing. Running the DuDu support system does not require this tool.

Key capabilities
Event editing
Create event fixtures from built-in templates and edit callback fields with descriptions.
Signing and encryption
Construct signatures and encrypted payloads for supported channel protocols.
Scripts and orchestration
Arrange event execution to reproduce integration scenarios.
Run records
Review run results and receipts to investigate protocol integration issues.
How it works
- Configure the target URL and test settings for your local receiving service.
- Choose a built-in template or saved event, edit fields and arrange scripts.
- Run in the desktop app and inspect receipts, signatures and receiving-service results.
Requirements and scope
Full local storage, signing and sending require the desktop environment. Successful simulation does not establish platform authorization or production messaging.
The modules work together: Admin provisions organizations, Console configures teams and channels, Desk handles conversations, and Server provides shared services. MockPulse is an optional development tool.
