query parameters:
-
All inventory summaries with all available detail are returned when the
startDateTime
andsellerSkus
parameters are omitted. -
When
startDateTime
is provided, the operation returns inventory summaries that have changed after the date and time specified. ThesellerSkus
parameter is ignored.
Avoid pagination errors
To avoid errors, use both
startDateTime
andnextToken

- When the
sellerSkus
parameter is provided, the operation returns inventory summaries for only the specifiedsellerSkus
.

General Recommendation
NextToken in GetInventorySummariesResponse
To avoid errors, use nextToken
to get the next page within 30 seconds.
Pagination in GetInventorySummariesResponse
When a call to the **getInventorySummaries**
operation produces a nextToken
, then there are inventories that have not been encountered yet and you can get them on the subsequent calls. You iterate through the Inventories using the nextToken
token provided in successive responses. All inventory has been traversed, only after the pagination
is returned in response. This means the inventorySummaries
list can be empty but still produce a nextToken
.
Examples:
Even if there are no inventories in the inventorySummaries
list, there is a nextToken
:
{
"response": {
"pagination": {
"nextToken": "XXXXXXXXX"
},
"payload": {
"granularity": {
...
},
"inventorySummaries": []
}
}
}
The getInventorySummaries
operation is considered done only when the pagination
is not returned in the response:
{
"response": {
"payload": {
"granularity": {
...
},
"inventorySummaries": []
}
}
}
