IBM Security Verify

Here is the requirement:
• I want to pull all users who have Attribute X with Value Y

Issue:
• The GET /v2.0/Users API only returns a MAX TotalResults of 2500 entries

Question:
• Since we have millions of accounts, how can I programmatically find all accounts that meet my requirement as opposed to just 2500?
• Is there a different API that I should be using?
• Or, how can I change the API totalResults default value (i.e., I know that changing the value will result in a slower response)

Actual Command that I am running:
GET >> https://fcis.ice.ibmcloud.com/v2.0/Users?filter=urn:ietf:params:scim:schemas:extension:ibm:2.0:User:pwdReset%20eq%20%22true%22&attributes=userName&count=500&startIndex=1

•This requires the following:
{
"totalResults": 2500,
"startIndex": 1,
"itemsPerPage": 500,
"schemas": [
"urn:ietf:params:scim:api:messages:2.0:ListResponse"
],
"Resources": [
{

• Even if I remove the filter parameter all together, the API only ever returns a max totalResults of 2500

Since the API supports Paging, I tried making the startIndex 2501 to essentially start getting the next batch of 2500 accounts; however, that just returns the following:

{
"totalResults": 2500,
"startIndex": 2501,
"itemsPerPage": 0,
"schemas": [
"urn:ietf:params:scim:api:messages:2.0:ListResponse"
],
"Resources": []
}
