HaloPSA REST API fundamentals: OAuth 2.0 client-credentials authentication, authorization vs. resource server URLs, the tenant query parameter, filtering and pagination conventions, array-wrapped POST bodies, rate-limit behavior, scopes, and error codes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HaloPSA API Patterns
## Overview
The HaloPSA REST API provides access to all PSA entities including tickets, clients, assets, contracts, and more. This skill covers OAuth 2.0 Client Credentials authentication, tenant configuration, query patterns, pagination, and error handling.
## Authentication
### OAuth 2.0 Client Credentials Flow
HaloPSA uses OAuth 2.0 Client Credentials flow for API authentication. This is different from basic API key authentication - you must obtain an access token before making API requests.
### Server URLs
HaloPSA has two server URLs:
| Server | Purpose | Example |
|--------|---------|---------|
| **Authorization Server** | Token endpoint | `https://yourcompany.halopsa.com/auth` |
| **Resource Server** | API endpoints | `https://yourcompany.halopsa.com/api` |
Find these in **Configuration > Integrations > HaloPSA API > API Details**.
### Token Endpoint
```
POST https://{base_url}/auth/token?tenant={tenant_name}
```

How to install
mdr add wyre-ai/msp-claude-plugins/HaloPSA API Patterns@sha256:c8df46d51e216f99The line at the top of this page pins the label git:20260728.b7e78fc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
