# BasicAuth

## Encoding API Key <a href="#encoding-api-key" id="encoding-api-key"></a>

To encode API keys, follow the authentication method below.

1. Indicate Authorization: Basic "user-uid:api key" in the header.
2. Replace the "user-uid" and "api key" values with the necessary ones.
3. Encode the whole string in [base64](https://en.wikipedia.org/wiki/Base64).

**For example**:

The following **user-uid:api key** string `777c31b3-a85f-4823-93a5-9055d1b:cGEFFLjYuUCtmerXlhTfAdaPpYVnXDJZmg`\
results in a\
**base64** `Nzc3YzMxYjMtYTg1Zi00ODIzLTkzYTUtOTA1NWQxYjpjR0VGRkxqWXVVQ3RtZXJYbGhUZkFkYVBwWVZuWERKWm1n`\
Thus, the header should look like this:\
**Authorization: Basic**\
`Nzc3YzMxYjMtYTg1Zi00ODIzLTkzYTUtOTA1NWQxYjpjR0VGRkxqWXVVQ3RtZXJYbGhUZkFkYVBwWVZuWERKWm1n`
