Configuring n8n HTTP Request Pagination with Relative next_url Values

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm using n8n's built-in pagination feature to fetch all pages from an API that returns 1586 results with a maximum of 500 per page
I begin with the first page and use the provided next_url in the API response to retrieve subsequent pages, aiming to collect all four pages of data

Below is my current configuration for the HTTP Request nodes, including the pagination settings:

JSON
{  
  "nodes": [  
    {  
      "parameters": {  
        "url": "<https://home.smelogin.co.uk/api/v1.2.0/owner?page=1&page_size=1>",  
        "sendHeaders": true,  
        "headerParameters": {  
          "parameters": [  
            {  
              "name": "accept",  
              "value": "application/json"  
            },  
            {  
              "name": "X-API-KEY",  
              "value": "XXXXXXXXXXX"  
            }  
          ]  
        },  
        "options": {  
          "pagination": {  
            "pagination": {  
              "paginationMode": "responseContainsNextURL",  
              "nextURL": "=<https://home.smelogin.co.uk>{{$json[‘value’][‘meta’][‘next_url’]}}",  
              "paginationCompleteWhen": "other",  
              "completeExpression": "={{ $json[‘value’][‘meta’][‘next_url’].match(/page=(\d+)/) && $json[‘value’][‘meta’][‘next_url’].match(/page=(\d+)/)[1] ? false : true }}"  
            }  
          }  
        }  
      },  
      "id": "d073d4b3-7996-4335-9a50-8dd20d98c882",  
      "name": "HTTP Get Owner",  
      "type": "n8n-nodes-base.httpRequest",  
      "typeVersion": 4.2,  
      "position": [  
        480,  
        0  
      ]  
    },  
    {  
      "parameters": {  
        "url": "<https://home.smelogin.co.uk/api/v1.2.0/owner?page=1&page_size=500>",  
        "sendHeaders": true,  
        "headerParameters": {  
          "parameters": [  
            {  
              "name": "accept",  
              "value": "application/json"  
            },  
            {  
              "name": "X-API-KEY",  
              "value": "5ddf8eb8b0924"  
            }  
          ]  
        },  
        "options": {}  
      },  
      "id": "6191a163-4f18-43db-9f59-48bb21b777b7",  
      "name": "HTTP Get Owner1",  
      "type": "n8n-nodes-base.httpRequest",  
      "typeVersion": 4.2,  
      "position": [  
        240,  
        0  
      ]  
    }  
  ],  
  "connections": {  
    "HTTP Get Owner": {  
      "main": [  
        [  
          {  
            "node": "HTTP Get Owner1",  
            "type": "main",  
            "index": 0  
          }  
        ]  
      ]  
    },  
    "HTTP Get Owner1": {  
      "main": [  
        [  
          {  
            "node": "HTTP Get Owner",  
            "type": "main",  
            "index": 0  
          }  
        ]  
      ]  
    }  
  },  
  "pinData": {}  
}

The output received from the last node is as follows:

JSON
[  
  {  
    "value": {  
      "meta": {  
        "dataset_last_modified": {  
          "date": "2025-02-07 10:55:40.000000",  
          "timezone_type": 3,  
          "timezone": "Europe/London"  
        },  
        "total": 1586,  
        "page_size": 500,  
        "page": 2,  
        "next_url": "/api/v1.2.0/owner?page=3&page_size=500"  
      }

I'm open to any guidance or suggestions, as I'm fairly new to automation and would appreciate any insights to correctly configure pagination.

Below is some advice and a revised configuration that should help resolve your issue.

Key Recommendations

Return a Complete URL:
Since your API returns a relative URL (e.g., "/api/v1.2.0/owner?page=3&page_size=500"), you need to prepend your host. For example, if your domain is https://home.smelogin.co.uk, the expression should join the base URL with this relative path.
Use Standard Quotes:
Ensure you’re using plain single (') or double (") quotes within your expressions rather than smart quotes. This avoids syntax errors when evaluating JavaScript.
Simplify Your Completion Check:
Instead of using a regex to check for a page parameter, you can simply check if the meta.next_url exists. When it’s empty, there’s no next page.

Revised Pagination Configuration

Below is an example configuration for the HTTP Request node’s pagination settings:

JSON
"options": {
  "pagination": {
    "pagination": {
      "paginationMode": "responseContainsNextURL",
      "nextURL": "{{ 'https://home.smelogin.co.uk' + $json.value.meta.next_url }}",
      "paginationCompleteWhen": "other",
      "completeExpression": "{{ !$json.value.meta.next_url }}"
    }
  }
}

Explanation:

nextURL Expression:
The expression concatenates your host ('https://home.smelogin.co.uk') with the relative next_url from the response.
completeExpression:
The configuration checks if meta.next_url is falsy (i.e., when there is no next page the pagination stops).

Additional Tips

URL Format:
Verify that the output in your API response always includes the key meta.next_url correctly.
Page Size Consideration:
Since you mention a maximum of 500 per page, ensure the URL you are paginating with uses page_size=500 consistently.
Testing:
Double-check your API output in the response so that the expression can correctly parse the next URL.

This setup should allow the node to automatically fetch all four pages (1 + 3 additional calls) until no further pages are available.

Happy automating!
