WORKFLOW ACTIONS

What you can configure.

Choose an action in the workflow builder, connect an account, and map its inputs. These actions are available in the catalog; your account access and a successful test determine whether they work for your setup.

Publish MQTT message

Write

Send a text message to one broker topic.

Permissions and limits

Account permissions

  • Broker topic publish permission

Operation limits

  • QoS 0 confirms only a local send. QoS 1 waits for broker PUBACK, not subscriber delivery.
  • An uncertain publish response is not retried automatically.

A repeated request may repeat the external action. Review the previous result before retrying a write.

SETUP

Start with a controlled test.

01Connect the intended account

Use the account and permissions required for your process. Review the connection check before configuring a workflow action.

02Review inputs and access

Select a listed operation and map its required inputs. Use test records and add a human approval before writes that need review.

03Confirm the result

Inspect step outputs and confirm the result in MQTT. A saved workflow is not a completed provider action.
