Mark Ark video completion on the related Slack message
Close the loop on a video request where the team already discussed it. Send Notis a webhook completion signal with the Slack channel, message timestamp, and task context.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Once a video job finishes, the Slack conversation may still look unresolved, leaving people to ask whether the output is ready.
- Make a completed task visible on its existing Slack message.
- Reduce follow-up questions in the original conversation.
- Reuse task and message references supplied by the external process.
Setup
Build it in a few focused steps.
- 1Connect BytePlus Ark and Slack once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, tell Notis to add a chosen reaction to the referenced Slack message when the request reports completion.
- 4Pick a Notis webhook trigger and choose where run reports should go.
- 5Send one real completion example with a valid channel and message timestamp, then check the reaction.
Questions about this workflow
Can Notis watch Ark for completed tasks by itself?
No completion trigger is listed for BytePlus Ark. An external process must send a webhook request to Notis when it has the completion information.
What is needed to react to the correct Slack message?
The request needs to identify the Slack message, including its channel and timestamp. Include a task reference as context if useful.
Does this workflow post the generated video?
No. The listed Slack action adds a reaction to an existing message. It does not upload or share an Ark video file.
