## Which one, for what

### Google Ads API (BB)

Good for: It suits an agent that reports on or manages Google Ads accounts for an advertiser or agency that can get a Cloud project approved.

Ahead on:
- Reliability, 82 against 34
- Schema & documentation, 84 against 56
- Agent ergonomics, 87 against 57
- Security & auth, 71 against 65
- Payments & pricing, 40 against 20
- Maintenance & community, 87 against 61
- Transparency & trust, 82 against 69

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine

Watch for: One OAuth scope, `adwords`, covers reading, editing, creating and deleting. Read-only access depends on the Google Ads user role

### 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.

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

## Verdicts

**Google Ads API.** Test accounts are free and need no approval, and `validate_only` checks a change without running it. Production access needs a Google Cloud project approved at Explorer level or above and a person to set up OAuth. One OAuth scope covers both reads and writes. The official MCP server is read-only, self-hosted and at version 0.0.4.

**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

### Google Ads API

1. Send `validateOnly: true` on a mutate first. It returns errors without making the change. Batch jobs don't support it
2. Create campaigns with status PAUSED and enable them in a separate step, since an enabled campaign with a budget can spend
3. Send `login-customer-id` (digits only, no hyphens) when you reach a client account through a manager account
4. A failed request still counts against the daily operation quota. Paging with a valid `next_page_token` doesn't
5. Wait at least 12 hours between account budget changes on one account, and use the Data Manager API for new Customer Match or offline conversion work

### 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
