How to Handle "Content-Type" in a Post Request Header

ValueDescription
application/jsonIndicates that the request body format is JSON.
application/xmlIndicates that the request body format is XML.
application/x-www-form-urlencodedIndicates that the request body is URL encoded.

In some scenarios, for example, when we are going to send POST requests from a shopify form, it doesn’t allowed to use any Content-Type other than the last one in the above table.
Okay, then how can we configure the payload? You might be laughing, I had been stuck though. 😉
If you already got an object to send via POST, set the body like this:

1//Content-Type: 'application/json'
2body: JSON.stringify(obj)
3//Content-Type: 'application/x-www-form-urlencoded'
4body: `payload=${JSON.stringify(obj)}`

Yes, that’s exactly how it works! Check it now on the recipient server.

1console.log(JSON.parse(request.body.payload))

It should show your submitted object exactly.
Happy coding, gents! 🙂
