Pagination, setting stop condition

[Javibg6]

Describe the problem/error/question

I’m retrieving from an API a list of conversations. There’s a page parameter, and for every request I get 25 items.
I added pagination options and, using pageCount+1, I’m able to retrieve several pages.
The problem comes with the condition I have to set so that the module stops executing when there’s no more content.

If i call this API and set the page to 200, I get the following (simplified) response:

[
  {
    "data": {
      "meta": {
        "mine_count": 64,
        "assigned_count": 64,
        "unassigned_count": 358,
        "all_count": 422
      },
      "payload": []
    }
  }
]

The key here is that the array payload is empty. I should be able to set the condition so that, if the current response’s payload is empty, then stop making HTTP requests.

I also tried with other options, like creating a set field, and update it after an if condition… It didn’t work neither. Plus, it seems like a more complex solution, and i believe that i’m near to getting this fixed. The only thing i need is the proper condition to stop :S

Can anyone help me solve this? Thanks in advance!

What is the error message (if any)?

Tip for sharing information

Pasting your n8n workflow

---

Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

That implies to any JSON output you would like to share with us.

I think you are missing body in your expression. It could look like this:

{{ $response.body.data.payload.isEmpty() }}

Thanks Ihortom! You are right, it worked!!
Simple and effective solution. chatGPT got me trying crazy stupid things, but i knew it should be a simple condition.

Thanks a lot! I will edit the JSON so that it is easier for others to see!
