Thank you, this was the first Postman Mocking tutorial I found that explained it in a way I could follow.

Thank you so much. I was having trouble understanding how to mock POST requests, and now it makes a lot more sense

[karlkrasnowsky]

Thanks... I was trying to figure out how these examples worked when defining the mock server. From another tutorial it seemed that you did this from the mock server directly, not the collection... so the mock is created via information that comes from the collection, not the other way around. This makes sense.

Hi I am new to postman, i have a question please. do we always have to manually add queries params and their examples with the json that needs to be a response? is there another way where we can add json that has many users in one example then we can pass queries dynamically and we fetch user id without manually creating ids?

@Tutorials Pedia - At 18:01 why did you get 404 error whereas it should have returned 400 as the bad request. 404 is file not found.

Can I use this mock server For This Mutation in react?
I didn't find any video for this topic, please create a video for this one
Here's an example of a mutation that adds a new todo to the server:



function App() {
const mutation = useMutation({
mutationFn: newTodo => {
return axios.post('/todos', newTodo)
}
})

return (
<div>
{mutation.isLoading ? (
'Adding todo...'
) : (
<>
{mutation.isError ? (
<div>An error occurred:
) : null}

{mutation.isSuccess ? <div>Todo added!</div> : null}

<button
onClick={() => {
mutation.mutate({ id: new Date(), title: 'Do Laundry' })
}}
>
Create Todo
</button>
</>
)}
</div>
)
}
