Webhook Component

Table of Contents

Description

The Webhook component receives data at the specified URL to initiate your workflow.

Credentials

The Webhook component supports the following authorization methods:

  • No Auth - Use this method to interact with any open REST API.
  • Basic Auth - Utilize this method to provide login credentials. This method includes the following fields:
    • Username - (string, required)
    • Password - (string, required)
  • API Key Auth - Use this method to provide an API key as part of the headers to access the resource. This method includes the following fields:
    • Header Name - (string, required)
    • Header Value - (string, required)
  • HMAC (sha256/sha512) verification with shared secret - Use this method to verify requests using a shared secret. This method includes the following fields:
    • Header Name - (string, optional, defaults to x-eio-signature)
    • HMAC (sha256/sha512) verification shared secret - (string, required)

Triggers

Receive

This is a simple webhook trigger that receives data as input and initiates the execution of the workflow.

Output Metadata

The message body emitted from the webhook will contain:

  • A JSON object that was transferred using the POST method or query parameters in the case of a GET request.
  • _query (object) - Contains the query parameters.
  • _headers (object) - Contains the headers of the received request.
  • _method (string, POST or GET) - Indicates the HTTP method of the received request.
  • _url (string) - The full URL that was received.

Webhook Response

By default, the webhook URL will respond with the following structure:

{
    "requestId": "86ad47dfbce4a8ae8a1eb505b85d8bd5",
    "message": "thank you"
}

However, you can specify the exact content of the reply using the HTTP Reply component. In this case, you will receive a reply only when the message reaches the step where the HTTP Reply is used, or if an error occurs in other steps between the Webhook step and the HTTP Reply.

Known Limitations

  • Currently, the component supports the following HTTP methods: POST and GET.
  • When using a POST request, only JSON or XML data can be transferred to the workflow; other types, such as text or files, are not supported.
  • XML data will be automatically converted to JSON format.
  • The base path of the URL begins with the keyword hook followed by the flow ID, for example, /hook/678119de28021e00129641fe. You can append the desired path only after this base path, such as /hook/678119de28021e00129641fe/sales/orders.
