Which one, for what

Amazon EventBridge BB

Good for Teams already on AWS that want events routed between AWS services, their own code and outside HTTPS endpoints under IAM, with retention and replay on the bus.

Ahead on

  • Security & auth, 88 against 53
  • Payments & pricing, 35 against 30
  • Transparency & trust, 87 against 67

Also in its favour

  • Agent-ready, a grade of BB or better
  • A hosted endpoint, with nothing to install
  • No incidents deducted, where Convoy loses 6 points for them

Watch for

Classic PutEvents has no idempotency token or deduplication, and failed entries come back inside a successful response for the caller to resend

Convoy B

Good for A product that has to send signed webhooks to its customers' endpoints with retries, replay and a delivery log, or receive third-party webhooks and route them inward.

Ahead on

  • Reliability, 92 against 73
  • Maintenance & community, 80 against 75

Also in its favour

  • Free to start without a card

Watch for

Advisory GHSA-p5vg-v7mj-f6q4 (24 July 2026, High) let a caller on one project read another project's source and broker credentials before v26.6.8

Verdicts

Amazon EventBridge

IAM policies scope a credential to single actions and buses, and an SLA commits 99.99 per cent monthly uptime per Region. The Custom Event Bus API of 24 September 2026 adds retention, replay, ordering and publish-time deduplication. Classic PutEvents takes no idempotency token and answers 200 for a bus that does not exist. A person must open the AWS account.

Convoy

Convoy Cloud runs the same HTTP API as the self-hosted gateway, with a public OpenAPI spec of 68 operations, project-scoped keys, idempotency keys on events and replay endpoints. Two credential exposures were fixed in July and August 2026, one published as a high-severity advisory. Cloud access needs a browser signup, and the trial allows 100 events a day.

Before you call either

Amazon EventBridge

  1. Use aws eventsv2 and the EventBridgeV2 SDK client for the Custom Event Bus, but write IAM actions with the events: prefix. A policy naming eventsv2: grants nothing
  2. After a Classic PutEvents call, check FailedEntryCount and each entry's ErrorCode, then resend failed entries yourself. A request holds up to 10 entries and under 1 MB
  3. Set SystemMetadata.DeduplicationId on Custom Event Bus entries when retrying a publish, and treat a SuccessCode of DEDUPLICATED as success
  4. Set RetryPolicy and OnFailureConfiguration when creating a subscriber. The defaults stop after 5 attempts or 300 seconds, and an exhausted event is dropped
  5. Store the full bus ARN. A Custom Event Bus ARN ends in a generated identifier that changes when a bus of the same name is recreated

Convoy

  1. Use the regional base URL, https://us.getconvoy.cloud/api/v1 or https://eu.getconvoy.cloud/api/v1. A project key works only under /projects/{projectID}/
  2. Create an endpoint, then a subscription, then the event. An event sent to an endpoint with no subscription isn't dispatched
  3. Send idempotency_key on every event. A repeated key creates the event but no delivery, and the key stays reserved until retention deletes the event
  4. Create projects with a personal API key and the orgID query parameter. The project key in that response is shown once
  5. Before retrying an endpoint or subscription create, list endpoints by ownerId. Idempotency keys cover event ingestion only
