URL Fetch
This service allows scripts to access other resources on the web by fetching URLs. A script can use the UrlFetch service to issue HTTP and HTTPS requests and receive responses. The UrlFetch service uses Google's network infrastructure for efficiency and scaling purposes.
Requests made using this service originate from a set pool of IP ranges. You can look up the full list of IP addresses if you need to whitelist or approve these requests.
The default user agent string of UrlFetch service requests is Mozilla/5.0 (compatible; Google-Apps-Script; beanserver; +https://script.google.com; id: SCRIPT_ID).
This service requires the https://www.googleapis.com/auth/script.external_request scope. In most cases Apps Script automatically detects and includes scopes a script needs, but if you are setting your scopes explicitly you must manually add this scope to use UrlFetchApp.

HTTPResponse Methods Method Return type Brief description getAllHeaders() Object Returns an attribute/value map of headers for the HTTP response, with headers that have multiple values returned as arrays. getAs(contentType) Blob Return the data inside this object as a blob converted to the specified content type. getBlob() Blob Return the data inside this object as a blob. getContent() Byte[] Gets the raw binary content of an HTTP response. getContentText() String Gets the content of an HTTP response encoded as a string. getContentText(charset) String Returns the content of an HTTP response encoded as a string of the given charset. getHeaders() Object Returns an attribute/value map of headers for the HTTP response. getResponseCode() Integer Get the HTTP status code (200 for OK, etc.) of an HTTP response.
