Conclusion

In this documentation, I’ve explored the “send message” endpoint within the SafeChat application. This endpoint allows users to engage in chat conversations while ensuring a secure and positive user experience. I’ve covered the request format, expected responses, and various error scenarios to help you understand how the endpoint functions.

Error Handling

1: HTTP Status 404 Not Found: This error occurs when either the sender or receiver specified in the request is not found in the database. Please ensure that valid user IDs are provided for successful message delivery.

2: HTTP Status 409 Conflict: This conflict status is triggered when the sender and receiver are the same individuals, preventing the message from being sent. It is designed to avoid self-messaging within the system.

3: HTTP Status 208 Already Reported: This status is raised when malicious content is detected in the message content. As a security measure, the user responsible for the malicious content will be removed from the database.

4: HTTP Status 400 Bad Request: This status indicates a general issue with the request or can result from an AppException. Please ensure that your request follows the specified format and handle any AppExceptions accordingly.

5: HTTP Status 406 Not Acceptable: This status is returned when users are not following each other, preventing them from engaging in a chat conversation. Ensure that both users have an established following relationship to initiate a chat.

I hope this documentation serves as a helpful guide for using the “send message” endpoint effectively and safely within SafeChat. If you have any questions or encounter any issues, please don’t hesitate to reach out to me via okoroaforkelechi123@gmail.com or my phone number 09152624528.

SafeChat values the security and satisfaction of its users, and we’re committed to providing a safe and enjoyable messaging experience for all.

Thank you for choosing SafeChat!
