+# MyCase Piece
+
+This piece provides integration with MyCase API using OAuth 2.0 authentication.
+
+## Features
+
+### Authentication
+- **OAuth 2.0**: Uses Authorization Code grant flow with refresh tokens
+- **Automatic Token Management**: Handles access token and refresh token lifecycle
+- **Secure**: Follows MyCase's recommended authentication practices
+
+### Actions
+- **Get Firm Information**: Retrieve information about the authenticated firm
+- **List Contacts**: Retrieve and search contacts with pagination support
+
+## Authentication Setup
+
+### Prerequisites
+1. **MyCase Account**: You need an active MyCase account
+2. **Client Credentials**: Contact MyCase support to obtain:
+   - Client ID
+   - Client Secret
+   - Redirect URI (must be pre-registered with MyCase)
+
+### OAuth 2.0 Flow
+1. **Authorization**: Users are redirected to MyCase authorization server
+2. **Code Exchange**: Authorization code is exchanged for access token
+3. **API Access**: Access token is used for authenticated API requests
+4. **Token Refresh**: Refresh tokens are used to obtain new access tokens
+
+### Configuration
+- **Authorization URL**: `https://auth.mycase.com/login_sessions/new`
+- **Token URL**: `https://auth.mycase.com/tokens`
+- **Token Lifetime**: 24 hours (access token), 2 weeks (refresh token)
+- **Rate Limits**: 25 requests per second per client
+
+## API Integration
+
+### Base URL
+All API requests are made to: `https://api.mycase.com/v1`
+
+### Authentication Header
+```
+Authorization: Bearer <access_token>
+```
+
+### Error Handling
+- **401 Unauthorized**: Access token expired (automatic refresh handled)
+- **Rate Limiting**: 25 requests per second limit enforced
+- **Scope Validation**: Ensures required permissions for API endpoints
