Prepare text for systems that expect Base64
When a process requires Base64 input, turn a clearly identified Slack text snippet into the right representation and report the result.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Base64 Encode
Tool to encode a string to Base64. Use when you need to convert text into Base64 representation for use in other operations.
Why this helps
Copying text into an encoding utility interrupts work and creates opportunities for a selection mistake.
- Remove a manual copy-and-encode detour.
- Prepare selected text for a compatible process.
- Keep the conversion tied to its source conversation.
Setup
Build it in a few focused steps.
- 1Connect Slack and Encodian to Notis once in the portal.
- 2Create an automation prompt specifying which text snippets need Base64 encoding and what downstream use requires it.
- 3Pick the Slack Channel Message Received trigger and choose a channel for run reports.
- 4Test with non-sensitive sample text and confirm the receiving process can use the output.
Questions about this workflow
Should I encode all Slack messages?
No. Use a narrow prompt for messages and text that a compatible downstream process actually needs.
Is Base64 encryption?
No. Base64 is an encoding format and does not protect confidential content.

New Channel Created Trigger
Triggered when a new channel is created in Slack.
Compare Text
Tool to compare two text strings and determine if they match. Use when you have two strings and need to verify if they are equal.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Hash Data
Tool to compute a cryptographic hash (MD5, SHA256, etc.) of text or file data. Use when you need to verify integrity or generate digests.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Unzip File
Tool to extract files from an archive. Use when you need to unzip a package and retrieve its contents.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
