## Which one, for what

### LinkedIn Marketing APIs (B)

Good for: An agent that reports on and manages LinkedIn campaigns for accounts its operator administers, especially read-only reporting, which has no account limit on Development tier.

Ahead on:
- Reliability, 66 against 34
- Schema & documentation, 66 against 56
- Agent ergonomics, 63 against 57
- Payments & pricing, 30 against 20
- Transparency & trust, 84 against 69

Watch for: Standard rate limits are not published. An app sees its limit in the Developer Portal only after calling the endpoint

### Snapchat Ads API (D)

Good for: An agent that manages or reports on Snapchat campaigns for an advertiser whose admin can create an OAuth app.

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No OpenAPI specification, Postman collection or Ads API SDK was found in the reviewed documentation

## Verdicts

**LinkedIn Marketing APIs.** Monthly API versions are each supported for at least a year, with dated sunsets and a changelog, and a test ad account lets an agent create campaigns that are never served or billed. Access needs LinkedIn's approval and a member's OAuth consent, standard rate limits are not published, and no OpenAPI specification was found.

**Snapchat Ads API.** The docs are served as Markdown with an llms.txt index, rate limits are published as 20 requests a second per app and 10 per token, and test ad accounts never serve live ads. No OpenAPI specification, status page, SLA, idempotency key or Ads API SDK was found, and one OAuth scope covers both reads and writes.

## Before you call either

### LinkedIn Marketing APIs

1. Send `Linkedin-Version: YYYYMM` and `X-Restli-Protocol-Version: 2.0.0` on every call. A missing or sunset version returns an error (426 for a deprecated one)
2. Create one test ad account with `"test": true` and build there first. Its creatives are auto-rejected and never billed, and it returns no reporting data
3. Create campaigns as DRAFT or PAUSED and check `servingStatuses` before activating. Some validation is postponed until activation
4. Pass `fields=` on adAnalytics. Responses stop at 15,000 elements and the endpoint throttles at 45 million metric values per 5 minutes
5. On Development tier, map each ad account to the app in the Developer Portal. Edits are limited to five accounts

### Snapchat Ads API

1. Refresh the access token every 60 minutes with the refresh token. An expired token returns 401 with `WWW-Authenticate: Bearer error="invalid_token"`
2. Create a test ad account with `"test": true` and build there first, and create campaigns with `"status": "PAUSED"`
3. Change one field with PATCH (JSON Patch). A PUT that omits attributes resets them to their defaults
4. Send money as micro-currency, where 1.00 of the account currency is 1,000,000
5. Page lists with `limit` (50 to 1,000) and follow `paging.next_link`. Use `async=true` for large stats pulls, since an oversized response fails with `E9001` and a retry does not help
