Send verification code with workflow

When you have collected a user's phone number, start the verification process by sending a verify request to the Verify API. This example includes use of a specific workflow for the request.

The Verify API returns a request_id. Use this to identify a specific verification request in subsequent calls to the API, such as when making a check request to see if the user provided the correct code.

Replace the following variables in the sample code with your own values:

Name	Description
`NEXMO_API_KEY`	Your Nexmo API key
`NEXMO_API_SECRET`	Your Nexmo API secret
`RECIPIENT_NUMBER`	The phone number to verify
`BRAND_NAME`	Included in the message to explain who is confirming the phone number
`WORKFLOW_ID`	Choose a workflow (number between 1 and 7), these are defined in the workflows guide

Write the code

Add the following to send-verification-code-with-workflow.sh:

Copy to Clipboard

curl -X GET "https://api.nexmo.com/verify/json?&api_key=$NEXMO_API_KEY&api_secret=$NEXMO_API_SECRET&number=$RECIPIENT_NUMBER&brand=AcmeInc&workflow_id=$WORKFLOW_ID"
