Dynamic Variables – Headers

Adding dynamic variables into the headers that are sent to your API is possible using the headers_variables parameter.

An example might be that you need to send a base64 encoded authorisation header.

Using Template Tag

Here is how we would dynamically encode the string and send as an Authorization header.

// encode the string
$encoded = base64_encode( $username . ':' . $password );

// call the API using the wpgetapi_endpoint() template tag
$data = wpgetapi_endpoint( 'myapi', 'myendpoint', 
	array( 
	    	'debug' => true, 
	    	'header_variables' => array( 
	    		'Authorization' => 'Basic ' . $encoded 
	    	), 
	) 
); 

// you now have the data stored within $data to use however you like
echo $data;

Using Shortcode

Header variables are only available using the template tag.
