Webhooks
This documentation applies to the following products:
Super SIM
Programmable Wireless
Ensure you follow the guide to link your Twilio account to KORE before continuing.
For all other products, please review their respective documentation.
Follow these steps to start receiving Webhook events from KORE.
1. Securing your Webhook - Secret Generation
Securing your Webhook with a secret isn't mandatory, but KORE strongly encourages you to validate that the Webhook comes from KORE.
The secret should only be known by you and KORE. Treat this as you would your password, and do not share it.
To create your first KORE Webhook secret, log in to the Developer Portal, navigate to the Webhook page, and click Create.
Provide a friendly name to your secret and click Create.
View or download the newly created Secret and save it.
A secret is visible or downloadable only at the time of creation. If you forgot to save it, review our guide to rotate your secret to generate a new one.
The newly created secret details will be listed.
Once you have generated your first Webhook secret, all Webhook callbacks from KORE will be signed, and you can then validate.
2. Configure a Webhook URL with the Super SIM API
The assumptions are:
You have created an API client to make API calls against KORE with a Super SIM scope; if not, review the getting started guide.
You have SIMs in either an Active or Inactive state.
We will configure a Webhook on a Super SIM API endpoint to get started and flip a SIM's status from inactive to active.
Activating a SIM will incur a monthly SIM fee and any data charges you generate.
With your API token and Super SIM SID, make the following API call to activate your Super SIM ensuring you specify a value for CallbackUrl
.
If the CallbaackUrl parameter has more than one query parameter, the URL must be data-urlencoded.
For example:
If your callback URL is https://mycallback.com?foo1=bar1&foo2=bar2
KORE will send the events to https://mycallback.com?foo1=bar1.
You will need to replace &
with %26
. So, the callback URL you specify in the API call should be https://mycallback.com?foo1=bar1%26foo2=bar2
.
KORE does not look at query parameters when generating a signature.
4. Receiving and Responding to Webhook
Once you submit your API call with a Webhook configured, you will receive a callback from KORE with the HTTP headers mentioned here ( a sample is shown below).
Upon receiving this, you should respond with a 2xx HTTP response code. Any temporary failures (HTTP response codes 408, 429, or 5xx) will be automatically retried a pre-determined amount of times, which is defined by the Retry Count
Connection Setting.
