WebHooks using parse cloud function
Following parameters needed to implements webhooks in parse
- master: Set true if the master key was used and otherwise set false.
- user: If set, this will contain the Parse User who made the request, in our REST API format. This is not set if the master key is used.
- installationId: If you want to add installation Id which made the request.
- params: You can pass your parameters in JSON format.
- functionName: Your application Cloud function name.
you can specify triggers names like beforeSave and afterSave on objects, as well as when a Cloud Function is called.
Create new Webhooks section located in the Core dashboard. Enter webhook type ,function name and server URL, for example, let’s say you want to hit your server at www.abcexample.com whenever a “USER” class object is saved. All you have to do is specify this as a beforeSave webhook:
In parse, You can also write parse web-hook function in cloud code. The code like this:
1 2 3 4 5 |
{ "object": { "className": "User",
"name": "name",
"email":”[email protected]",
"age": 1 },
"triggerName": "beforeSave" }
|
Here User is your table name.in parse your Table name is called class Name.
When Parse receives a request to save a User, server will receive a POST with the JSON payload.
WUsing After Save
Just change trigger name to
1 2 3 4 |
{"object":{"className":"User",
"Name":"name",
"Age":""8";},
"triggerName":"afterSave"}
|
