Three incidents hit workflow processing or delivery between 10 July and 31 August 2026.\n\n**Pingram.** Email and SMS go out through one REST call with built-in delivery, per-message prices are public and the free tier needs no card. No rate limits or idempotency keys were found in the reviewed documentation, and the MCP connector acts with the signed-in user's whole account.\n\n## Before you call either\n\n### Knock\n\n1. Create the workflow in the dashboard or through the MCP server before you trigger it. Triggers reference it by key\n2. Send an `Idempotency-Key` on every trigger. It holds 24 hours and only the trigger endpoint accepts it\n3. Pass a `cancellation_key` when you trigger so a later cancel call can stop a delayed or batched run\n4. Use a service token only for headless MCP sessions, since it skips consent and enables every capability\n5. Keep test and production apart. Rate limits and keys are scoped to an environment\n\n### Pingram\n\n1. Use the API host for the account's region. The key and region (`us`, `eu` or `ca`) come from the API Keys page in the dashboard\n2. Keep the `trackingId` from each send and check Logs before retrying. No idempotency key was found, so a blind retry can send twice\n3. Pass `accountId` on MCP tools when the user belongs to several accounts. Without it the tools use the earliest account joined\n4. Create broadcasts as drafts only. Pingram's own skill says a person must send a broadcast from the dashboard\n5. Expect 402 when the monthly budget is spent. Unused balance does not roll over\n\n## Questions\n\n### Which is better for AI agents, Knock or Pingram?\n\nKnock scores 66.5 (B) on agent readiness against Pingram's 57.4 (C), and leads in 4 of 7 scored categories.\n\n### Do Knock and Pingram need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Knock and Pingram without installing anything?\n\nYes.
