# Pagination

When using the [Call connector endpoint](https://tray.ai/documentation/developer/platform-apis/connectors#endpoint-call-connector), certain 3rd party operations such as Salesforce 'List records' or Marketo 'List leads' may return long lists of data which will need to be paginated.

This can be dealt with using parameters such as `batch_size`, `next_page_token` etc.

**The exact pagination parameters will depend on the service**.

You can use our  to check the input and output schema for each operation to look for any pagination parameters.

The following shows an example input for the Salesforce 'List Records' operation which passes a `batch_size` and `page_offset` token to obtain next page of records:

```json request
{
  "operation": "find_records",
  "authId": "a5f886xx-xxxx-xxx-xxx-xxf9459933",
  "input": {
    "object": "Account",
    "batch_size": 200,
    "page_offset": "0r84J1RcJ9gaMpWQKU-200",
    "fields": ["Id", "Name"],
    "conditions_type": "Match any conditions"
  },
  "returnOutputSchema": false
}
```

```json 200 response
{
  "outcome": "success",
  "output": {
    "total": 31,
    "next_page_offset": null,
    "records": [
      {
        "Id": "0018d00000r3ynkAAA",
        "Name": "Heaney, Lebsack and Brekke"
      },
      {
        "Id": "0018d00000r3ynlAAA",
        "Name": "Hegmann Inc"
      },
      ...
      ...29 More Records
      ...
    ]
  }
}
```

The **token for the next batch** and e.g. 'has more’ information will be **returned in the 200 response**.
