Send a verification code
Starts verifying a phone number or email address by sending a one-time code over SMS, WhatsApp, a voice call or email.
Note: Create a Verify Service first and pass its SID (VA...) as --service-sid.
Set up
Use the first option your agent supports.
CLI (official)
Install the command, then confirm it runs.
brew tap twilio/brew && brew install twilio
twilio --version
Run twilio api:verify:v2:services:verifications:create.
Set $TWILIO_API_KEY in your environment first (get a key: https://www.twilio.com/docs/iam/api-keys/keys-in-console).
Note: Also set TWILIO_ACCOUNT_SID and TWILIO_API_SECRET, with TWILIO_API_KEY holding the API key SID, or sign in once with twilio login.
Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.
Rules
- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
