# Mastering Business Central API for App Management

[Read the post](https://aardvarklabs.blog/2026/09/18/mastering-business-central-api-for-app-management/) · Aardvark Labs (Marcel Chabot) · 2026-09-18 · 1200 words · tier community · reviewed (checked by Opus)

> This post provides practical PowerShell examples for automating extension management in Business Central using the Administration API, including deploying .app files, monitoring installation progress, handling failures, and uninstalling extensions.

## Key points

- Get a bearer token via the client credentials flow and reuse the header for every Administration API call
- Install a .app through the pteInstall endpoint with a multipart form request carrying the file plus deploymentSchedule, syncMode, languageId, acceptIsvEula and dependency options; the upload is limited to 50 MB
- Poll the app operations endpoint to track the deployment until it reports succeeded, failed or canceled, with failures returning an error message
- Before uninstalling, call uninstallRequirements; then post to the uninstall endpoint with update window, dependents and delete-data settings and poll until done

## Quotes

- "To uninstall an extension, we first check whether any dependencies must be removed." (Checking dependencies before uninstall prevents errors and ensures safe removal of extensions)

## Context

- Features: Extension installation, Extension uninstallation, App deployment scheduling, Dependency checking, Operation monitoring, Multipart file upload, Environment management
