1️⃣ Use HTTPS
This ensures that all communication between the client and the server is encrypted.

2️⃣ Use Authentication.
Authentication is used to validate the identity of the client who is attempting to make a connection.
When a client requests an API, it may be necessary for the client to provide some sort of credentials to prove they are who they claim to be.

When a client requests an API, it may be necessary for the client to provide some sort of credentials to prove they are who they claim to be.
Let's mention two types of authentications:
{1} JWT (JSON Web Tokens) authentication
This allows the server to authenticate the client using a JSON object, which is signed by the server and sent to the client.
{1} JWT (JSON Web Tokens) authentication
This allows the server to authenticate the client using a JSON object, which is signed by the server and sent to the client.
The client then sends this token back to the server with each request, allowing the server to verify the authenticity of the request.
{2} OAuth authentication
This allows a client to access resources on a server on behalf of a user without the client needing to know the user's login credentials.

3️⃣ Use rate limiting:
This involves limiting the number of requests a client can make to the server in a given time period.
This can help protect against denial of service attacks and other types of abuse.

4️⃣ Use input validation
All input data must be validated to comply with the API specifications.
This can help protect against injection attacks and other types of malicious input.

5️⃣ Use proper error handling
This involves handling errors consistently, securely and returning appropriate error messages to the client.
This can help prevent sensitive information from being leaked to attackers.
