API keys and webhooks
Create and revoke API keys, add a webhook with its own signing secret, and send a test delivery — all from Developer.

API keys
New key creates one. Name it after where it will be used, so you know what to revoke later.
Revoke stops a key immediately. To change a key: create the new one, start using it, then revoke the old one.
No key is made for you — you only have the keys you created.
Webhook
Add a URL and Numestri POSTs every code to it as it arrives, for one-time numbers and for every message a rental receives.
Adding the webhook shows its signing secret. Your server uses it to check each delivery really came from Numestri.
Send test delivers a signed sample so you can check your receiver.
Rotate secret issues a new secret at once — update your server straight after.
Remove turns the webhook off.
The full details — payloads, headers, verification code and retries — are in the API docs.
