The one paginated carrier endpoint
GET /v2/upstream/policies/{policyId}/transactions and its v1 twin GET /v1/policies/{policyId}/transactions are paginated. Both accept page (default 1) and limit (default 50, maximum 100) and return a page envelope, not a bare array.
The envelope carries the same total, page, limit and totalPages fields as an agency list, but keys its array on transactions, not items. That is the older convention and it is frozen where it is.
Paging an agency endpoint
Two query parameters, on every list:
A request above the limit is refused rather than quietly reduced, so a client asking for 500 finds out immediately instead of paging through a result it believes is complete.
page reaches totalPages, or until items comes back empty. Both are reliable.
items, not the resource name. Every agency list uses the same key, so one generic client type reads all of them. The paginated carrier endpoint (GET /v{1,2}[/upstream]/policies/{policyId}/transactions) is the one place a paginated array carries the resource name instead.Ordering is stable across pages
Every agency list sorts by a meaningful key and then by record id. That second term is what makes paging safe: ordering by a non-unique key alone lets records shift between pages as you walk them, so you see one twice and miss another entirely, with no error anywhere. You do not need to do anything for this. It is worth knowing because it is the reason you can trust page 2 not to repeat page 1.Filtering
Filters are per endpoint and documented on each reference page. The common ones on the agency surface:downstreamEntityIdβ narrow a list to one of your entities. An id outside your organization returns 404. It is accepted on 21 of the 24 paginated agency lists; the three market sub-lists (/v2/downstream/markets/{upstreamDownstreamAssociationId}/documents,/entity-contactsand/market-contacts) do not take it. Those three accept only the association id in the path, pluspageandlimit.stateCode,statusβ on licence and appointment lists.categoryβ on documents.producerIdβ on producer-scoped lists.
Sorting
Sort order is fixed per endpoint and chosen to match how the list is read β documents and filings newest first, entities and contacts by name. There is nosort parameter.
