JSON Encoding

JSON is a popular format in which services exchange information. Functions allow parsing and modifying these payloads to integrate different services with each other.

Some of the examples that you can do:

Decode Stripe webhook and encode it into a Slack or Discord notification.
Change Mailgun delivery notification into a Discord message.
Send an email when a change is pushed to a specific Bitbucket branch.

Decode JSON

To decode or encode JSON in a JavaScript function, use the global JSON object:

// example payload:
// {
//   "user": "Peter",
//   "age": 25,
//   "city": "Edinburgh"
// }

var payload = JSON.parse(request.body);

// now, payload is a normal JavaScript object and we
// can access individual values

request.body = payload.user;
// request will now have a single value 'Peter' in the body

Encode to JSON

To encode a structure back into a JSON string:

// constructing a new object that we will encode
// into a JSON string
var newPayload = {
    action: "hello", 
    message: "world"
};

// encoding
request.body = JSON.stringify(newPayload);

// webhook request body is now changed to:
// {
//   "action": "hello",
//   "message: "world"
// }
