Add post request to the order status page (thank you page)

Technical Q&A
1

Hi!

I have tried to add POST request in the additional scripts, but I have an error: "SyntaxError: Unexpected end of input ".

I have added to the fetch’s config “mode: ‘no-cors’”, but it still not working. What I’m doing wrong?

Do I need to create an App for it? If yes, how I can add the script to the order status page?

async function myFetch() {
          try {
            const data = {
              "email": "test@gmail.com",
              "code": "2IQ46Z5YBO"
            }
            const config = {
              method: 'POST',
              headers: {
                  'Accept': 'application/json',
                  'Content-Type': 'application/json'
              },              
              mode: 'no-cors',
              body: JSON.stringify(data)
            }
            let response = await fetch('https://s6rn91hrs3.execute-api.us-east-2.amazonaws.com/campaigns/claim', config);

            let result = await response.json();
              console.log(response)
          } catch(e) {
            console.log(e);
          }
        }

myFetch();
