Webhooks

Webhooks are a way for an app to send automated real-time notifications to another app when a specific event occurs. In Manifest, there are 8 predefined events where you can hook HTTP requests.

Webhooks are useful to connect other applications or to trigger a micro-service like notifying someone or update a file.

Syntax

manifest/backend.yml

entities:
  # You can attach one or several webhooks to each entity event.
  Cat 😺:
    properties:
      - name
    hooks:
      beforeCreate:
        - { url: 'https://my-webhook.com' }

  Dog 🐶:
    properties:
      - name
    hooks:
      afterDelete:
        # Pass .env variables with ${} interpolation.
        - {
            url: 'https://another-webhook.com',
            headers: { authorization: 'Bearer ${API_KEY}' }
          }
        # Specific HTTP method.
        - { url: 'https://another-one.com', method: 'PATCH' }

Webhook params

You can pass arguments using the long syntax:

Option	Default	Type	Description
url*	-	string	The URL of your webhook
method	POST	HTTP Method	The HTTP method of the request
headers	{}	object	Optional headers of the request. Use ${MY_DOTENV_VAR} syntax to use dotenv variables

Available HTTP Methods are GET, POST, PUT, PATCH and DELETE.

note

Manifest does not enforce HTTP request success or failure; the lifecycle process continues regardless.

Webhook body

Manifest attaches a JSON body with key information about the record concerned to the webhook HTTP request.

The main structure of the body of the triggered HTTP requests will remain the same and only the record value will change: on before events the record will contain your payload, whereas in after requests, the record value will reflect the item after the operation.

This is the structure of the body:

HTTP request body (content-type is application/json)

{
  "event": "beforeUpdate",
  "createdAt": "2025-01-22T13:38:48.399Z",
  "entity": "posts",
  "record": {
    "title": "my title",
    "content": "my content"
  }
}
