Check how to authenticate the APIs. All Razorpay APIs are authenticated using `Basic Auth`. Basic auth requires the following: * `[YOUR_KEY_ID]` * `[YOUR_KEY_SECRET]` Basic auth expects an `Authorization` header for each request in the `Basic base64token` format. Here, `base64token` is a base64 encoded string of `YOUR_KEY_ID:YOUR_KEY_SECRET`. **Watch Out!** The `Authorization` header value should strictly adhere to the format mentioned above. Invalid formats will result in authentication failures. Few examples of **invalid** headers are: `BASIC base64token`, `basic base64token`, `Basic "base64token"` and `Basic $base64token`. ## Generate API Keys You can generate API Keys from the Dashboard. Follow these steps to generate API keys: Watch this video to see how to generate API keys in the Test mode.
