Loop Returns

Loop Returns is an AI-powered post-purchase operations platform built for e-commerce retention that unites tracking, returns, exchanges, fraud prevention, and shipping into a single platform. Originally built for Shopify, Loop now supports all e-commerce platforms and enables brands to transform returns into revenue-retaining exchanges. The platform provides a REST API for creating return authorizations, tracking return status, managing exchange workflows, generating labels, and triggering refunds. Developers can also configure programmatic webhooks to receive real-time event notifications for returns, shipments, labels, and gift cards. API access is gated by scoped API keys passed via the X-Authorization header, with OAuth 2.0 required for the Label and Webhooks APIs.

Loop Returns publishes 7 API contracts indexed on the APIs.io network, including Cart API, Destinations API, Fraud Reports API, and 4 more. Tagged areas include Returns, E-Commerce, Refunds, Shipping, and Post-Purchase.

The Loop Returns catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Loop Returns’ developer surface includes authentication, documentation, pricing, engineering blog, changelog, and 17 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-11-06 · rubric v0.27.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
  • MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
  • Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
  • Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
  • Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
  • Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
