I've been trying to send a JSON payload through a JS script but my webhooks seem unable to see the payload whatever I write.
Here is the code I put together from various online sources:
let xhr = new XMLHttpRequest();
xhr.open("POST","https://webhook.site/4530328b-fc68-404a-9427-3f2ccd853066/",true);
xhr.setRequestHeader("Content-Type", "application/json");
let data = JSON.stringify({'eventType' : 'test'});
xhr.send(data);I'm not a JS developer but it seems to me that this should work. However every time I run this snippet the POST URL does not show anything back :/
Any idea why that is over here :) ?
Thank you for your time!
In your example, the webhook.site service you're attempting to connect to with your JavaScript isn't enabled (by default) with the proper CORS headers that modern browsers respect & enforce to improve user security. The developer console in your browser of choice should point this out to you; the error mine gave back was:
Access to XMLHttpRequest at 'https://webhook.site/5c7a5049-9c5e-4bf7-b1cf-0e05f6503bfa' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
As the error states, the requested resource doesn't respond with any valid Access-Control-Allow-Origin header, which will prevent the POST itself from being fully executed. In webhook.site, you can select the CORS Headers tickbox from the top of the user interface to enable the service to send the proper CORS headers to get this working.
let xhr = new XMLHttpRequest();
xhr.open("POST","https://webhook.site/5c7a5049-9c5e-4bf7-b1cf-0e05f6503bfa",true); // configuration interface at https://webhook.site/#!/5c7a5049-9c5e-4bf7-b1cf-0e05f6503bfa/e14fc471-4bc4-410f-b16a-0755a231fb12/1
xhr.setRequestHeader("Content-Type", "application/json");
let data = JSON.stringify({'eventType' : 'test'});
xhr.send(data);I suggest you to use axios, it gonna be something like this and you will get the response from your post request
const response = await axios.post('https://webhook.site/4530328b-fc68-404a-9427-3f2ccd853066/', {'eventType' : 'test'});
