Hey there! Let me break this down clearly since you had trouble wrapping your head around the ServiceNow docs. These four "set" links are ServiceNow's built-in way to simplify pagination in REST queries, so let's start with what each does, then tackle your question about replacing sysparm_limit/sysparm_offset.

What Do First/Previous/Next/Last Set Do? #

When you query a large dataset via ServiceNow's REST API, the platform automatically paginates results (or you can enforce a page size with sysparm_limit). In the HTTP response headers, you'll get a Link field that includes these four pre-built URLs. Each link is pre-configured with the correct sysparm_limit and sysparm_offset values, so you don't have to calculate them manually:

• First set: This link points directly to the first page of results. The URL will have sysparm_offset=0 and whatever sysparm_limit you're using (either the default or your custom value). Use this to jump back to the start anytime.
• Previous set: Only appears if you're not on the first page. This link takes you to the page immediately before your current one—its sysparm_offset is automatically calculated as your current offset minus the page size. No math required.
• Next set: Only appears if there are more results left to fetch. This link jumps to the next page, with sysparm_offset set to your current offset plus the page size. Perfect for sequential browsing.
• Last set: This link takes you straight to the final page of results. ServiceNow calculates the total number of records, divides by your page size, and sets the correct sysparm_offset in the URL so you don't have to figure out how many pages there are.

Can They Replace sysparm_limit/sysparm_offset? #

Short answer: No, they don't replace those parameters—they wrap them. Here's why:
Every one of those "set" links includes sysparm_limit and sysparm_offset under the hood. For example, if you're on page 2 (offset=10, limit=10), the "next set" link will be a URL with sysparm_limit=10&sysparm_offset=20.

That said, they do make pagination easier in specific scenarios:

• Use the pre-built links if you're browsing sequentially (first → next → next, or backtracking to previous pages) or need to jump to the start/end without calculating offsets.
• Stick to manually setting sysparm_limit/sysparm_offset if you need to jump to a specific page (e.g., "go to page 5") or customize pagination logic beyond simple sequential navigation.

Also, important note: You can't send first/prev/next/last as request parameters—these are only provided as ready-to-use URLs in the response's Link header. You'll need to parse that header to extract the URLs for subsequent requests.
