Social Service Integration (Permission Check)

Description

Connect the Chat Service to the Social Service to verify friendship before allowing messages to be sent.

---

Features

1. Call Social Service Endpoint

• Use HTTP module to call the Social Service's friendship check endpoint
• Send request with sender ID and recipient ID
• Receive friendship status response

2. Check Friendship Status

• Before sending a message, verify if sender and recipient are friends
• Block message if they are not friends
• Allow message only if status is FRIENDS

3. Error Handling

• If Social Service is down, show error to user
• If users are not friends, show error message
• Display error as a toast notification to sender

What Needs to Happen

When user tries to send a message:

1. Capture sender ID and recipient ID
2. Call Social Service API endpoint
3. Get friendship status response
4. If FRIENDS → Allow message to be sent
5. If NOT FRIENDS → Block message and show error toast
6. If Social Service fails → Show error toast

Error Messages:

• "You are not friends with this user"
• "Failed to verify friendship status"
• "Social Service is currently unavailable"
