Balance

Retrieve the current balance of your Nexmo account

Not Authorised. You must supply your `api_key` and `api_secret` as query parameters to this request

Top Up Account Balance

You can top up your account using this API when you have enabled auto-reload in the dashboard. The amount added by the top-up operation will be the same amount as was added in the payment when auto-reload was enabled. Your account balance is checked every 5-10 minutes and if it falls below the threshold and auto-reload is enabled, then it will be topped up automatically. Use this endpoint if you need to top up at times when your credit may be exhausted more quickly than the auto-reload may occur.

Secret Management

Many of Nexmo's APIs are accessed using an API key and secret. It is recommended that you change or "rotate" your secrets from time to time for security purposes. This section provides the API interface for achieving this. Note: to work on secrets for your secondary accounts, you may authenticate with your primary credentials and supply the secondary API keys as URL parameters to these API endpoints.
