Developers

Your CRM has a dev loop

Plugins are real C# against a typed SDK — scaffolded, validated, registered, executed, and time-travel debugged without leaving VS Code.

Plugin model

Three kinds of plugin, one language

Server plugins for data logic, form plugins for UI behavior, action plugins for commands — all C# class libraries with full IntelliSense, your test framework, and normal code review.

Server

Runs in the data pipeline on create/update/delete. Typed access to the target record plus ICrmService for queries, writes, and actions.

Form

Reacts to form load and field changes through IFormExecutionContext — 30+ typed UI actions like setting requirement, visibility, and focus.

Action

Backs toolbar buttons with arguments. Same form context, fired on click, with field mutations applied back to the open form.

VS Code extension · early access

Time-travel debug your plugins

The CosmicXRM VS Code extension scaffolds plugins, validates on save with in-editor diagnostics, registers to a connected environment, and runs your code in the sandbox with an input-vs-modified diff. Then the part you don't get anywhere else: step through a recorded execution — timeline, live variables, and the active line lit in your source.

The CosmicXRM time-travel debugger: execution timeline on the left, source with the active line highlighted, variables pane, and trace output — A recorded run of a deal-scoring plugin: step 3 of 6, line 8 active, variables and trace captured at every step. Rendered by the extension's own debug panel.

Scaffold & register

CXRM: Create Plugin templates all three kinds; registration uploads source — including multi-file shared libraries — straight to your environment.

Run in the sandbox

CXRM: Run Plugin executes against the test sandbox: reads hit live data, writes roll back, and you get an input-vs-modified diff.

Debug the whole pipeline

CXRM: Pipeline Debug replays every plugin registered on an entity and message, in order, in the same time-travel view.

The extension is in early access. Get in touch to try it.

API

An API that mirrors your model

Everything the apps do goes through the REST API, described by an OpenAPI document that reflects your metadata. Authenticate interactively with Microsoft Entra ID, or machine-to-machine with scoped API keys.

The same typed SDK your plugins use is available for integration code, so queries and writes look identical inside and outside the platform.

                    terminal

# Records, queries, and actions over REST
curl https://your-env/api/env/main/deal \
  -H "X-Api-Key: $CXRM_KEY" \
  -d '{ "name": "Carraway renewal",
        "value": 86000 }'
