Here are some examples of GraphQL queries and mutations for a todo API:

Queries:

• query { todos { id title completed } } - This query retrieves all the todos with their id, title, and completed status.
• query { todo(id: 1) { id title completed } } - This query retrieves a specific todo with id equal to 1.

Mutations:

• mutation { createTodo(title: "Buy groceries") { id title completed } } - This mutation creates a new todo with the title "Buy groceries".
• mutation { updateTodo(id: 1, completed: true) { id title completed } } - This mutation updates the completed status of the todo with id equal to 1 to true.
• mutation { deleteTodo(id: 1) } - This mutation deletes the todo with id equal to 1.

Queries:

• query { me { id username email } } - This query retrieves the currently authenticated user’s id, username, and email.

Mutations:

• mutation { register(input: RegisterInput!) { user { id username email } } } - This mutation creates a new user account with the provided input data.
• mutation { login(input: LoginInput!) { accessToken } } - This mutation authenticates a user with the provided input data and returns an access token.
• mutation { updateUser(input: UpdateUserInput!) { user { id username email } } } - This mutation updates the currently authenticated user’s account with the provided input data.
