How to post query parameters with Axios?

I am trying to post on an API with some query params. This is working on PostMan / Insomnia when I am trying to by passing mail and firstname as query parameters : http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName However, when I am trying to do it with my react native app, I got a 400 error (Invalid Query Parameters). This is the post method : .post(`/mails/users/sendVerificationMail`, { mail, firstname }) .then(response => response.status) .catch(err => console.warn(err)); (my mail and firstname are console.logged as follow: `lol@lol.com` and `myFirstName`). So I don't know how to pass Query Parameters with Axios in my request (because right now, it's passing `data: { mail: "lol@lol.com", firstname: "myFirstName" }`.
