Parse Cloud httpRequest Stripe Subscriptions at_period_end param - http

Question

Having trouble getting the format right with Parse.Cloud.httpRequest for deleting a subscription at_period_end.
I am able to successfully make this request with PostMan using x-www-form-urlencoded, key 'at_period_end' value true. (Can't post a screenshot due to my reputation sorry)
Here is my cloud-code:
Parse.Cloud.httpRequest({
method : 'DELETE',
url : 'https://' + skey + ':#' + 'api.stripe.com/v1' + '/customers/' + request.params.customerId + '/subscriptions/' + request.params.subscriptionId,
body : {
"at_period_end": true
},
success: function(httpResponse) {
if (httpResponse.status === 200) {
response.success(httpResponse);
}
else {
response.error(httpResponse);
}
},
error: function(httpResponse) {
response.error(httpResponse);
}
});
I have played around with adding a headers object with Content-Type set, but unsuccessful.
I think this is just a formatting translation issue from what I correctly entered into PostMan, to what is in my httpRequest object...
I also can't find any great information on docs on the httpRequest method so its quite frustrating :(.
Thanks heaps
***** EDIT ****** SOLUTION:
Managed to solve this using url inline parameters:
var options = request.params.options,
url = 'https://' + skey + ':#api.stripe.com/v1/customers/' + request.params.customerId + '/subscriptions/' + request.params.subscriptionId,
keys;
keys = Object.keys(options);
// This is disgusting, I need to know a better way.
for (var i = 0; i < keys.length; i++)
{
if (i === 0)
{
url += '?';
}
url += keys[i] + '=' + options[keys[i]];
if (i !== keys.length - 1)
{
url += '&';
}
}
Parse.Cloud.httpRequest({
method : 'DELETE',
url : url,
success: function(httpResponse) {
if (httpResponse.status === 200) {
response.success(httpResponse);
}
else {
response.error(httpResponse);
}
},
error: function(httpResponse) {
response.error(httpResponse);
}
});
if anyone could show me a better way to write this, that would be epic :)
Cheers

Answer 1

This one has always been particularly thorny for me, here is what I've been using that has worked:
Parse.Cloud.httpRequest({
method: 'DELETE',
url: 'https://api.stripe.com/v1/customers/' + request.params.stripeId + '/subscriptions/' + request.params.stripeSubscriptionId,
headers: {
'Authorization': 'Basic BASE_64_ENCODE_SECRET_KEY'
},
params: {
at_period_end: true
},
success: function(httpResponse) {
...
},
error: function(httpResponse) {
...
}
});
A couple of extra details here.
I initially had "Content-Type: application/json" as one of the headers, but this appears to not be correct, despite (I think) needing it in the past.
The base64 encode of your key can be generated with
echo -e 'sk_live_ABCDEF123456:' | openssl base64
Don't forget the colon (:) at the end of the key, it matters.
This is just a detail however, and it looks like putting the secret key directly in the URL is working as well.
