For WhatsApp groups

What are WhatsApp group automations

WhatsApp Group Automations help you manage your group chats. They can:

• Listen to messages and respond automatically

• Run predefined workflows

• Send announcements, reminders, and polls

• Welcome new members

• Track engagement and group activity

• Analyze messages to share insights

They are workflow automations that you can use to keep your WhatsApp groups active, organized, and responsive — even when you’re offline.

How WhatsApp automations work

1

The group

You add the CodeWords WhatsApp number ([phone]) to your WhatsApp group to link an automation.

2

Event detection

The configured automation listens for your defined trigger, key events — like messages, reactions, or new members.

3

Trigger your automation

When a trigger event happens, CodeWords automatically runs your custom WhatsApp automation.

4

Processes and responses

The workflow automation uses AI to analyze the message, take action, and send a response back to the group — just like a real assistant.

Event types the WhatsApp automations on CodeWords can detect

Event Type	When It Happens	Example Uses
message:in:new	When someone sends a message	Reply, log, or summarize content
group:update	Members join or leave	Welcome messages, update tracking
message:update	Polls or event changes	Share updated results
message:reaction	Emoji reaction added	Track engagement or popular messages

Setting up your first WhatsApp assistant

1

Build the assistant through chat

Describe the kind of WhatsApp Assistant you want to create with your defined trigger, this can be a workflow automation.

Example 1: "Create a WhatsApp Assistant for my group that’s connected to an LLM and automatically responds to any message from group members."

Example 2: "Create a WhatsApp Assistant for my group that takes article URLs posted, adds it to my notion table with metadata. Only trigger if there is URL that is posted."

2

Register your number

Tell Cody your number:

“Register my phone number [phone] for the WhatsApp group Assistant.”

Cody will create your registration and send setup instructions.

3

Add the CodeWords number to your WhatsApp group

1. Open your group → Tap group name → “Add participant”

2. Add [phone]

3. Confirm addition

You’ll see:

"[phone] was added"

4

Mention the assistant

In your group, type:

@CodeWords

You’ll get confirmation:

Assistant Successfully Linked!

5

Test your assistant

Send any message in the group — the Assistant will detect any trigger and respond through your Custom WhatsApp Group Assistant.

Connect an existing WhatsApp automation template

1

Access the template

Go to the Run Page for the WhatsApp Automation template and review its description to understand how it works.

2

Run the template

Enter your phone number (including country code), then run the automation template and register your number with the automation.

Cost

Automation Message Type	Cost per Message	Examples
Text, Poll, Event, Location	€0.002 + Cost of executing the Automation	“Daily update,” “New event added”
Image, Video, Audio, Document	€0.004 + Cost of executing the Automation	Reports, media summaries
Receiving messages	Free	You only pay for what the Automation sends

Privacy and data handling

Key principle: Ephemeral by default

Each run executes in a fresh sandbox that is destroyed after completion. Most runs complete in seconds, with a maximum lifetime of 30 minutes for complex workflows.

• Created new for each event

• Deleted after execution

• No local storage between runs

• No automatic data retention

Meaning:

• Your bot forgets everything after each run.

• Data is only kept if you explicitly choose to store it.

• This ensures privacy-first design — no accidental data retention.

Getting help

If your Assistant isn’t responding:

1. Confirm it’s linked (@CodeWords)

2. Ask Cody to verify your linked groups

3. Check in-app support or use live chat at codewords.ai

2. Add the CodeWords number ([phone]) to the group and mention @CodeWords bot. You’ll see a confirmation, and events start flowing to your workflow automation.

Do I register for each group?

Yes, you can refer to the steps here.

What happens when I mention CodeWords?

The bot captures the group ID, links it to your registration, posts a success message, and starts forwarding events to your Workflow.

Can one automation template handle multiple groups?

Yes. Enter your phone number (with country code) on the Assistant’s Run Page and start it. Then in WhatsApp:

1. Add the CodeWords number to the group you want to link

2. Mention it by sending: @CodeWords
