EventBridge integration | Flomation Support

00Overview

Publish custom events and define the rules that route them, then wire those rules to the targets they invoke — all from inside a flow. Manage the surrounding pieces too: event buses, API destinations and connections for calling external HTTP endpoints, plus archives and replays to capture events and re-run them over a chosen time window, and tags across all of it. You can also test an event pattern against a sample event before you rely on it in production.

Every field below is exactly what you see in the Flomation editor. Fields marked ● live picker let you choose from a list pulled live from your account — no IDs to look up.

01Connecting EventBridge

Choose how each EventBridge node authenticates using the Authentication dropdown, which offers Access Keys, Assume Role (cross-account) and Managed Role (Credential). Every method also needs a Region — the AWS region your event buses and rules live in (e.g. us-east-1).
For Access Keys: in the AWS console open IAM → Users (console.aws.amazon.com/iam), select or create a user with EventBridge permissions, and under Security credentials choose Create access key. Copy the Access key ID and Secret access key into the node's AWS Access Key and AWS Secret Key fields, and fill in Session Token (optional) only when you are using temporary STS credentials.
For Assume Role (cross-account): in IAM → Roles create a role whose trust policy lets Flomation's AWS principal call sts:AssumeRole, attach your EventBridge permissions to it, and paste its ARN into Role ARN to Assume. If the trust policy specifies an External ID, enter the same value in Assume Role External ID (optional) — with this method you never share your own keys, as Flomation signs the call with its own identity and assumes your role.
For Managed Role (Credential): pick a pre-configured AWS credential in the AWS Role Credential field — an admin sets these up once so operators can select one without handling any keys.
House style: rather than pasting the secret access key inline, store it as a Flomation environment secret (e.g. eventbridge_secret) and select it from the node's AWS Secret Key field.

Field	Type		Details
Authentication	`string`	Required	Access Keys, Assume Role (cross-account), Managed Role (Credential)
AWS Access Key	`secret`	Required
AWS Secret Key	`secret`	Required
Session Token (optional)	`secret`
AWS Role Credential	`credential`	Required

Good to know

Pick an Environment on your flow (Flow Settings → Environment) so the secret resolves. Secret fields never show the value — they reference ${secrets.your_secret}.

16Notes & Limitations

Behaviours and constraints worth knowing before you build with these nodes.

EventBridge is regional: rules, event buses, archives and connections exist only in the Region you select, so a resource created by a node pointing at one Region is invisible to any node pointing at a different Region.
A newly created rule matches events but does nothing until you attach one or more targets, so creating the rule and wiring up its targets are two separate steps.
Schedule-based rules — those that use a Schedule Expression rather than an event pattern — can only be created on the default event bus, not on a custom or partner event bus.
Deleting a rule fails while it still has targets, so remove those first; the Force option exists only to delete rules that an AWS service created on your behalf.
Publishing sends one event per run, so to emit several events at once, run the node once for each event rather than passing a batch.
