feat(support): Add Selling Partner API for Support v2025-02-01 - #960
Conversation
Implements the three Support API operations via a new SupportService,
exposed as AmazonConnection.Support:
- ListCases (POST /support/2025-02-01/cases): auto-pages on nextToken,
honours MaxNumberOfPages and surfaces NextToken on the parameter, with
ListCasesByNextToken for manual paging.
- GetCase (GET /cases/{caseId}).
- ListContacts (GET /cases/{caseId}/contacts): same paging pattern, with
ListContactsByNextToken.
Models under AmazonSpApiSDK/Models/Support are generated from Amazon's
support_2025-02-01.json in the existing swagger-codegen style. Fields the
model marks x-amzn-api-internal (ListCasesRequest.marketplaceId/sortField,
Case.lastOutboundDate) are omitted, as they are not in the public reference.
Parameterless JSON constructors are public to satisfy ExecuteRequestAsync<T>.
Amazon has not published usage plans for this API, so the rate limits are
conservative defaults (1 req/s, burst 1); the limiter adopts the
x-amzn-RateLimit-Limit header from the first response.
Also adds SupportSample.cs and a README section.
Tests: added SupportTests (13 cases) covering deserialisation of Amazon's
sandbox responses, request body and query serialisation, validation and
rate-limit registration. Full suite passes (17/17).

PhoneContenthas only a constructor with an optional parameter. Newtonsoft.Json can use it, but the other models in this PR declare an explicit[JsonConstructorAttribute]parameterless constructor. Match that convention. This makes deserialization behavior explicit.

Testing status: this has not yet been tested against the live Support API. The Selling Partner Support role is restricted and needs a Data Protection Policy review, which I have not completed yet. The implementation is covered by unit tests built from Amazon's sandbox responses in the published model, and the solution builds and passes the full suite. If anyone already holds the Selling Partner Support (Restricted) role, a quick |
The generated Equals compared list properties with SequenceEqual without checking the other instance's list, so comparing a model that has a list against one that does not threw ArgumentNullException instead of returning false. Raised by CodeRabbit on abuzuhri#960. Tests: added Equals_ReturnsFalseWhenOnlyOneSideHasAList. Full suite passes (18/18). Breaking: no
