Looking at the documentation, you still need query_type and marketplace_id in your request, as these are non-optional. So your code might need to look like this:

$resNextToken = $api->getShipments($query_type, $marketplace_id, $shipment_status_list, $shipment_id_list, $last_updated_after, $last_updated_before, $next_token);

If you don't need to pass other optional parameters, then:

$resNextToken = $api->getShipments($query_type, $marketplace_id, '', '', '', '', $next_token);

Hi @DomuITteam,

Thanks for your response.

But when I am including these params it returns same shipments twice

We don't have next pages still receiving next token which contains empty next page.

To start with, check if the payload from getShipments contains NextToken value, and if so, if it's empty or not.

If both are true, try this instead:

$next_token = $payload->NextToken;
$resNextToken = $api->getShipments(NEXT_TOKEN, $marketplace_id, '', '', '', '', $next_token);

Yes payload contains next token and its not empty but the issue is when I am making next request with next token it returns all the results similar to original one. Which makes the final list duplicate for each shipment.

Were you able to solve this problem? I am getting the same problem with next token. getting the same data with the next request using next token
