How to Generate Authorization Header

To authenticate requests, include the Authorization header in the format below:

Authorization: Basic base64(public_key:secret_key)

Step-by-Step:

1. Concatenate your public_key and secret_key with a colon (:)
   Format:

   public_key:secret_key

2. Encode the result in Base64.

3. Add it to the Authorization header like so:

Authorization: Basic <Base64_Encoded_String>

Example

If your credentials are:

• Public Key: your_public_key
• Secret Key: your_secret_key

Concatenate:

your_public_key:your_secret_key

Base64 encode the string:

eW91cl9wdWJsaWNfa2V5OnlvdXJfc2VjcmV0X2tleQ==

Set the header:

Authorization: Basic eW91cl9wdWJsaWNfa2V5OnlvdXJfc2VjcmV0X2tleQ==
