## Verdicts

**ActiveCampaign.** The v3 REST API covers contacts, segments, campaign scheduling and bulk import, with OpenAPI 3.1 definitions inside public Markdown reference pages and documented Retry-After on 429s. Each user has one unscoped API key, the limit is 5 requests a second, and no changelog was found. The status page shows three critical incidents between 27 July and 28 September 2026.

**MoEngage.** MoEngage publishes 36 OpenAPI files covering 140 operations, a per-endpoint rate limit table, Markdown docs and a hosted MCP server that builds drafts and leaves publishing to a person. No price, trial or self-serve signup is published, and on 17 August 2026 the Inform API in one data centre accepted requests for about 16 hours without sending the messages.

## Before you call either

### ActiveCampaign

1. Take the base URL from Settings, Developer in the account. Do not build it from the account name, because non-US accounts may not sit on api-us1.com
2. Use POST /contact/sync to upsert by email, and POST /import/bulk_import for up to 250 contacts, then read each row's outcome from GET /import/info
3. Page large contact sets with `orders[id]=ASC` and `id_greater`, not `offset`. Unsupported filter and order keys are silently ignored
4. Check `succeeded` in the body after scheduling, pausing or stopping a campaign. Business-rule failures return 200 with `succeeded` set to 0
5. Stay under 5 requests a second per account and wait for the Retry-After value on a 429

### MoEngage

1. Take the data centre number from the dashboard URL and call `https://api-{dc}.moengage.com`. Data can't be moved between data centres
2. Send an `Idempotency-Key` header (UUID v4) on V5 campaign writes and test sends, and a `transaction_id` on Inform alerts, which deduplicates for 5 minutes
3. Use internal event and attribute names in segment filters, and run `deep_validate_segment_filters` first. A wrong event name is accepted and the count later fails with no reason
4. Use `in` with a list for text equality in segment filters. `equals` returns a 400 that names no field
5. Reuse an OAuth access token until it nears expiry. The token endpoint allows 5 requests a minute and 30 per 10 minutes for each key
