Ok I am coming back to this after giving up in the past. I am trying to get a webhook to work with a sandbox account. I am using a url on a public server to receive the webhook response. I have subscribed the webhook successfully and I can see the subscription using the the "list subscription" function. I am trying to receive notifications for a phone call or incoming sms. If I call the sandbox number I do receive a notification from the webhook. Usually I get three one notification informing me a call was incoming a second notification that to me seems to contain all the same information as the first and a third notification that tells me the call was answered.
If I hang up right away I can also get a fourth notification telling me the call was ended but I have to hang up within a second of the call being answered otherwise the last notification is not sent.
At this point If I call back I do not receive any more notifications. I can repeat this with sms. I only seem to get three sms notifications than I am locked out for 15 min.
Using the "Get subscription" function I can see the subscription is still "Active" and after 15 min I can receive notifications again.
I also accidently came to realize that if I call from two, three, four phones at the exact same time I will get 3 notifications for each call as long as they are place at the same time. If I wait even a second after placing the first call I will not get any notifications for the second, or third call.
If I delete the subscription and set up a new one I still have to wait 15 min before I will receive any notifications. If I set up multiple notifications subscriptions I will receive 3 notifications for each subscription when I call similar to the description above.
The subscriptions always have a status of "Active" and never say blacklisted.
Any idea's is this issue because I am in sandbox mode. Is there a limit to the number of Notifications sandbox will send out. The code is not the problem because I can make a subscription and receive a response but I am only allowed three notifications. Is there a way to see why the notifications stop sending?
