Standard topics take no idempotency token, so a retried `Publish` can send twice. SNS has no user preferences, digests or in-app channel, email is plain text to confirmed subscribers, and SMS starts in a sandbox.\n\n**OneSignal.** Runs push delivery itself, so there's no separate push provider to wire up. Three incidents on the API and SDK endpoints in September 2026.\n\n## Before you call either\n\n### Amazon SNS\n\n1. Sign requests with SigV4 for service `sns` at `sns.\u003cregion\u003e.amazonaws.com`, or call `aws sns publish --topic-arn \u003carn\u003e --message \u003ctext\u003e` from the AWS CLI\n2. Track `MessageId` yourself on standard topics, because a retried `Publish` sends again. Use a FIFO topic with `MessageDeduplicationId` when duplicates matter\n3. Send per-channel text by setting `MessageStructure` to `json` and passing a JSON string with a `default` key plus keys such as `APNS`, `GCM`, `email` and `sms`\n4. Check `GetSMSSandboxAccountStatus` and the monthly spend quota before texting. Sandbox sends reach only verified numbers\n5. Expect an email subscription to stay in `PendingConfirmation` until the recipient clicks the link, and keep each email subscription under 10 messages a second\n\n### OneSignal\n\n1. Use `Authorization: Key \u003ckey\u003e`, not Bearer, and put `app_id` in the body\n2. Send an `idempotency_key` UUID with every create call and reuse it on each retry\n3. On 429, wait for `Retry-After`, then back off with jitter, up to 10 attempts\n4. Stay under 10 sends per subscribed subscription in 15 minutes or the app is disabled\n5. Target people with `include_aliases.external_id` and set `target_channel`\n\n## Questions\n\n### Which is better for AI agents, Amazon SNS or OneSignal?\n\nAmazon SNS scores 72.8 (BB) on agent readiness against OneSignal's 69.3 (B), and leads in 4 of 7 scored categories. OneSignal leads on maintenance \u0026 community.\n\n### Do Amazon SNS and OneSignal need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Amazon SNS and OneSignal without installing anything?\n\nYes. Amazon SNS has a hosted endpoint at https://sns.us-east-1.amazonaws.com and OneSignal at https://api.onesignal.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/amazon-sns-vs-onesignal.json, and with the fewest tokens: https://www.anchorterminal.com/compare/amazon-sns-vs-onesignal.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"amazon-sns\", \"b\": \"onesignal\"}`.
