Question 1

How do I forward Slack messages to WhatsApp?

Accepted Answer

Use the Slack on channel message trigger to catch new posts, then connect a WhatsApp send text message node. Map the message text and author so the recipient sees the full context.

Question 2

Can WhatsApp messages be posted into Slack?

Accepted Answer

Yes. Start with the WhatsApp receive message operation and route the sender and text into a Slack send message to channel node. The team then sees and can respond to inbound WhatsApp messages from Slack.

Question 3

Can I forward only Slack messages that mention the bot?

Accepted Answer

Use the Slack on app mention trigger rather than the general channel message trigger. It fires only when the bot is @-mentioned, which keeps WhatsApp from receiving every channel message.

Question 4

How do I send a Slack file to WhatsApp?

Accepted Answer

Use the Slack on file shared trigger or get file information to obtain the file, then pass it to the WhatsApp send document or send image operation depending on the file type.

Question 5

Can I notify someone on WhatsApp about a Slack reaction?

Accepted Answer

Yes. Use the Slack on reaction added trigger, which fires when an emoji reaction is added. Connect it to a WhatsApp send text message node to alert a stakeholder that a message was acknowledged.
