Join us in San Francisco on the 29/30th of October for two days of developer workshops and technical talks

Check verification code

Check the verification code that a user has provided. Use the request_id that was received when the verification code was sent.

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
`REQUEST_ID`	The ID of the Verify request you wish to cancel (this is returned in the API response when you send a verification code)
`CODE`	The code the user supplies as having been sent to them

Write the code

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

Copy to Clipboard

curl -X GET "https://api.nexmo.com/verify/check/json?&api_key=$NEXMO_API_KEY&api_secret=$NEXMO_API_SECRET&request_id=$REQUEST_ID&code=$CODE"

We can use the application plugin for Gradle to simplify the running of our application. Update your build.gradle with the following:

apply plugin: 'application'
mainClassName = project.hasProperty('main') ? project.getProperty('main') : ''

Run the following gradle command to execute your application, replacing com.nexmo.quickstart.verify with the package containing CheckVerification:

gradle run -Pmain=com.nexmo.quickstart.verify.CheckVerification
