Installation

Our standard Docker images already include this plugin. If you use a -slim image or another setup, install it with the following command:

kestractl plugins get io.kestra.plugin:plugin-gcp --compatible-for $KESTRA_VERSION

For kestractl, use your Kestra version with --compatible-for, or specify an exact plugin version.

For Kestra CLI, replace LATEST with a specific version or version range to pin the plugin version.

Properties

agentId *string

The unique agent ID of the Brand Agent configured on the RBM platform

file *string

The file attachment URI (can be a public HTTPS URL or a Kestra internal storage URI)

Pebble expression referencing an Internal Storage URI e.g. {{ outputs.mytask.uri }}.

msisdn *string

The recipient's phone number (MSISDN) in E.164 format (e.g. +33612345678)

assets

Assets this task consumes as inputs or produces as outputs, for lineage tracking and the asset graph (Enterprise Edition). A flow declaring this property on a task is rejected in the open-source edition.

Definitions

io.kestra.core.models.assets.AssetsDeclaration

assetFailureBehaviorstring

Possible Values

IGNOREFAILWARN

Asset failure behavior

Behavior applied to the task state when a declared asset fails to render, emit, or be persisted (e.g. a lock conflict): FAIL escalates it to FAILED, WARN (default) warns it if it would otherwise succeed, IGNORE leaves the state untouched.

enableAutobooleanstring

Whether to auto-register assets referenced dynamically at runtime that are not statically declared in inputs or outputs.

inputsarray

The assets consumed as inputs.

impersonatedServiceAccount string

The GCP service account to impersonate

projectId string

The GCP project ID

scopes array

SubTypestring

Default["https://www.googleapis.com/auth/rcsbusinessmessaging"]

The GCP scopes to be used

serviceAccount string

The GCP service account

When unset or rendered to an empty value, Application Default Credentials are used (e.g. GOOGLE_APPLICATION_CREDENTIALS or the runtime's attached identity).

thumbnail string

Optional thumbnail image URI. Only applied when file is a public HTTPS URL; ignored when file is a Kestra internal storage URI

Pebble expression referencing an Internal Storage URI e.g. {{ outputs.mytask.uri }}.

workloadIdentityAudience string

Audience of the Workload Identity Federation provider

The full resource name of the workload identity pool provider, //iam.googleapis.com/projects/<number>/locations/global/workloadIdentityPools/<pool>/providers/<provider>. Required with workloadIdentityToken, and must match the aud claim of the token.

workloadIdentityToken string

OIDC token for Workload Identity Federation

When set together with workloadIdentityAudience, the token is exchanged at Google STS for federated credentials and no service account key is needed: Google verifies it against the identity provider that issued it. Use {{ oidcToken(audience='…') }} to have Kestra Enterprise mint one for the running execution. Combine with impersonatedServiceAccount to act as a service account the pool may impersonate, and set projectId explicitly since no key file carries it. Cannot be combined with serviceAccount.

Outputs

messageId string

The unique message ID assigned by the RBM platform

sendTime string

Formatdate-time

The timestamp when the message was sent
