Turn a Slack reaction into a Codemagic build
Mark a message ready and let Notis start the build while you stay in the conversation.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Start New Build
Tool to start a new build for an application with specified workflow and branch or tag. Use when you need to trigger a build programmatically. Either branch or tag parameter must be provided.
Why this helps
Build requests can get buried between a decision in Slack and the manual trip to Codemagic.
- Start the next build from a familiar signal in Slack.
- Keep release intent beside the discussion that produced it.
- Reduce the chance that an approved build request gets forgotten.
Setup
Build it in a few focused steps.
- 1Connect Slack and Codemagic to Notis once in the portal.
- 2Create an automation in the portal or ask Notis in plain language to start a Codemagic build when a chosen reaction is added to a release-ready Slack message.
- 3Select Message Reaction Added as the trigger and describe the app and branch in the instruction.
- 4Choose a channel for run reports, then test with one real release-ready message.
Questions about this workflow
Can the reaction start a build for a specific branch?
Yes. Include how Notis should identify the intended app and branch in the plain-language instruction, using context from the message.
Does this trigger run on every reaction?
Describe the intended reaction and release context in the instruction so Notis can distinguish the build signal.
