## API Keys & Authentication

*How to authenticate different parts of Corrily.*

An API key is needed when calling Corrily's API. API keys can be obtained from the `Resources` tab of the Dashboard. To
use an API key, just pass it using the `X-Api-Key` custom header field when sending a request.

For example, to fetch a price for a user you can use the cURL request below (notice where the API key goes):

```
curl --location --request POST 'https://client.corrily.com/v1/prices' \
--header 'X-Api-Key: <YOUR_API_KEY>' \
--header 'Content-Type: application/json' \
--data-raw '{
    "country": "US",
    "user_id": "bob",
    "products": [
        "monthly",
    ],
}'
```
