Que API calls in function - php

Question

I'm doing two calls to an API. The only thing that differ the two calls is the URL. What i basically wonder is how i can structure this a little (or alot) better? Maybe run them after each other in a que? Sometimes the second calls returns a "critical error" on the Wordpress page where it gets called.
Any suggestions?
private $oauth_Key = 'xxx';
private $oauth_consumer = 'xxx';
private $api_url = 'xxx';
private $cat_url = 'xxx';
try {
$oauth = new OAuth($this->oauth_Key, $this->oauth_consumer, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_AUTHORIZATION);
$oauth->fetch($this->api_url);
$response_info = $oauth->getLastResponseInfo();
header("Content-Type: {$response_info["content_type"]}");
$res = $oauth->getLastResponse();
$oauth2 = new OAuth($this->oauth_Key, $this->oauth_consumer, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_AUTHORIZATION);
$oaut2->fetch($this->cat_url);
$response_info2 = $oauth2->getLastResponseInfo();
header("Content-Type: {$response_info2["content_type"]}");
$res2 = $oauth2->getLastResponse();
} catch(OAuthException $e) {
echo "Exception caught!\n";
echo "Response: ". $e->lastResponse . "\n";
}

Just figured it out. Re structured the code a bit. See below:
private $oauth_Key = 'xxx';
private $oauth_consumer = 'xxx';
private $api_url = 'xxx';
private $cat_url = 'xxx';
try {
$oauth = new OAuth($this->oauth_Key, $this->oauth_consumer, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_AUTHORIZATION);
$oauth->fetch($this->api_url);
$response_info = $oauth->getLastResponseInfo();
header("Content-Type: {$response_info["content_type"]}");
$res = $oauth->getLastResponse();
$oauth2 = new OAuth($this->oauth_Key, $this->oauth_consumer, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_AUTHORIZATION);
$oauth2->fetch($this->cat_url);
$response_info2 = $oauth2->getLastResponseInfo();
header("Content-Type: {$response_info2["content_type"]}");
$res2 = $oauth2->getLastResponse();
} catch(OAuthException $e) {
echo "Exception caught!\n";
echo "Response: ". $e->lastResponse . "\n";
}
