You'd probably want to wrap what you've done up there into a function and do something like.

for ( $counter = 0; $counter <= 1906; $counter += 20) { $responseURL = 'https://api.hubapi.com/content/api/v2/blog-posts?hapikey=' . $apiKey . '&archived=false&limit=20&offset=' . $counter; $response = wp_remote_get($responseURL, $getArgs); process_API_results($response); } 

If you echo out those URL requests you get

https://api.hubapi.com/content/api/v2/blog-posts?hapikey=&archived=false&limit=20&offset=0 https://api.hubapi.com/content/api/v2/blog-posts?hapikey=&archived=false&limit=20&offset=20 https://api.hubapi.com/content/api/v2/blog-posts?hapikey=&archived=false&limit=20&offset=40 https://api.hubapi.com/content/api/v2/blog-posts?hapikey=&archived=false&limit=20&offset=60 https://api.hubapi.com/content/api/v2/blog-posts?hapikey=&archived=false&limit=20&offset=80

... etc
