Your Hologram webhook key is a device-specific identifier used to authenticate your SIM when using the Hologram embedded API. You can use the embedded API to send TCP/UDP messages or SMS to your device.
Where to find the SIM's webhook key
- First find the SIM's details page from the SIMs pages or using search.
- Open the Webhooks tab for the SIM, then pressing the Show key button in the Webhook key card.
- The key will display in the modal that appears. Here you can also copy the key or generate a new one. Device keys do not expire.
