## Which one, for what

### ShippyPro (D)

Good for: A European shipper or logistics platform with its own carrier contracts that already holds a ShippyPro Enterprise plan and wants rates, labels, pickups and tracking across many regional carriers through one API.

Ahead on:
- Reliability, 70 against 64
- Security & auth, 51 against 32

Watch for: The help centre says APIs can only be activated with an Enterprise plan, which has no public price and starts with sales

### ShipStation API (C)

Good for: An agent working inside a merchant's existing ShipStation account (orders, batches, inventory, labels), or a developer who wants a free sandbox through the ShipStation API plans.

Ahead on:
- Schema & documentation, 83 against 64
- Agent ergonomics, 64 against 46
- Payments & pricing, 40 against 5
- Maintenance & community, 73 against 25
- Transparency & trust, 64 against 58

Watch for: One API key with full account access. No scopes, read-only keys or approval step before a label is bought

## Verdicts

**ShippyPro.** Two OpenAPI 3.1 files, a published limit of 20 calls per 10 seconds and a 99.5 per cent monthly SLA with service credits are public. API access needs an Enterprise plan arranged through sales, no changelog or SDK was found, and label creation on v1 has no idempotency key.

**ShipStation API.** A public OpenAPI 3.1 contract with 173 operations, Markdown docs for agents and a free ShipStation API plan with a sandbox make a first rate quote or test label reachable without a contract. One API key carries full account access, with no scopes, read-only mode or idempotency keys on label purchases.

## Before you call either

### ShippyPro

1. Send `Authorization: Bearer <API key>` and POST a JSON body with `Method` and `Params` to `https://api.shippypro.com/v1/<Method>`. Parameter names are case-sensitive
2. Check `Status` and `ErrorMessage` in every `Ship` response. HTTP 200 with `Status` 2 means no label was created
3. Before retrying a failed `Ship` call, look the order up by `TransactionID`. v1 has no idempotency key, and each label counts against the plan
4. Test with the Generic carrier. `Ship` and `Edit` calls on a real carrier create real labels
5. Stay under 20 calls per 10 seconds, and use webhooks for tracking. The docs advise against `GetTracking` in bulk

### ShipStation API

1. Send the key in an `API-Key` header to https://api.shipstation.com/v2. A key that starts `TEST_` runs in the sandbox on the same host
2. Call GET /v2/carriers first. Rate and label calls need `carrier_ids` or a `carrier_id` and a `service_code` from that account
3. Don't blindly retry POST /v2/labels after a timeout. List labels first, then void a duplicate with PUT /v2/labels/{label_id}/void
4. Check the `errors` array on 2XX responses too, and read `error_source` to tell a carrier fault from a ShipStation one
5. On a platform (Standard or Premium) key every label is real and charged. Ask the owner before buying, and void test labels at once
