AdobeSign - Validation for webhook url failed

[Jan_Ae]

I’m trying to register a webhook using the AdobeSign API (v6) !. Upon sending the POST I get:

{

    "code": "INVALID_WEBHOOK_URL",

    "message": "Validation for webhook url failed. Please make sure that the webhook url responds with a valid HTTP response code and a valid client id."

}

The body I sent is:

{

    "applicationName": "Test application",

    "name": "Somename - 5c0bc93d-b955-4451-bbc1-3b7e92c1cd6c",

    "state": "ACTIVE",

    "scope": "ACCOUNT",

    "webhookSubscriptionEvents": [  "AGREEMENT_ACTION_COMPLETED"  ],

    "webhookUrlInfo": {

        "url": "https://jan.X.com:3443/api/v1/flows/callback/c8b76d29-93e7-4f25-915e-a8ab600e93d5"

    }

}

Sending a GET to the url, containing the header “X-AdobeSign-ClientId: Some rnd id” it returns {  "xAdobeSignClientId": "Some rnd id"}. Sending a GET to this url using my phone over 4G also returns this. It takes about 30 seconds for AdobeSign to return the 400 BAD REQUEST.

Thanks

After some better error handling,

{

"code":"INVALID_WEBHOOK_URL",

"message":"Validation for webhook url failed. Please make sure that the webhook url responds with a valid HTTP response code and a valid client id."

}

Did you create an application in the Adobe Sign UI?  To create a webhook, you need to have an application which in turn creates an applicationID, aka clientID.  You'll need to code a listener to return that clientID.

See: Documentation for more info.

Yes I did. Setting the url to another platforms like https://requestbin.com/ I actually recieve the GET validation call from Adobe Sign, this cann just cannot reach my application.

I can not create Webhook with port other than 443

This post seems to be a strongly related question, solving my question.
