Hello,
Can one App have multiple notification subscriptions for multiple delivery addresses by running the subscription request setup again for each new address? This can occur when an application changes environments (test, UAT, Production, etc.)
Hi Phong - The link you sent is not helpful. Our webhook is working but is returning a 400 error in response to the subscription request.
The documentation link in the page you reference is no longer valid and the code link contains no useful code.
Are there recent working code examples or other documentation that I can review?
Thanks.
How about using the sample code here. And or try first in your local host using ngrok tunnel.
Hi Phong - I moved the code as you suggested but that did not resolve the issue.
Below is the full error. The error content does not provide any specific details. Does the subscription request actually call the deliveryMode.address endpoint or is this error coming from the RingCentral side? Please review the request details for any missing or incorrect data.
Thank you.

This answer may help you. https://community.ringcentral.com/questions/888/unable-to-create-webhook-subscription.html
Thanks Phong for clarifying this.
We are having an issue subscribing to fax notifications. The error returned is not specific:
Content: {"errorCode":"SUB-522","message":"WebHook responds with incorrect HTTP status. HTTP status is 400","errors":[{"errorCode":"SUB-522","message":"WebHook responds with incorrect HTTP status. HTTP status is 400","status":"400"}],"status":"400"}
Our deliveryMode.address is on the internet and works when I post a payload from Postman but of course will return an error if there is no payload posted. We are getting and setting the Validation_Token in our API Controller.
Here is our webhook setup C# code that is throwing the error:
SubscriptionInfo subscriptionInfo = await restClient.Restapi().Subscription().Post(new CreateSubscriptionRequest
{
eventFilters = new[] { "/restapi/v1.0/account/~/extension/~/fax?direction=Inbound" },
expiresIn = 630720000, //20 years
deliveryMode = new NotificationDeliveryModeRequest
{
transportType = "WebHook",
address = "https://services-tst.americanportfolios.com/RingCentralAPI/fax/received", }
});
And Webhook C# API controller code that will receive the notifications:
[HttpPost("received")] //From RingCentral
public async Task GetFaxReceived([FromBody] dynamic eventPayload)
{
string str = HttpContext.Request.Headers["Validation_Token"];
await ringCentralProvider.GetFaxReceivedAsync(eventPayload); //just handles the payload
HttpContext.Response.Headers.Add("Validation_Token", str);
}
What are we doing wrong that you can see?
Thanks.
Can you try moving up the code to return the validation token like this
[HttpPost("received")] //From RingCentral
public async Task GetFaxReceived([FromBody] dynamic eventPayload)
{
string str = HttpContext.Request.Headers["Validation_Token"];
HttpContext.Response.Headers.Add("Validation_Token", str);
await ringCentralProvider.GetFaxReceivedAsync(eventPayload); //just handles the payload
}
