Question

How to create a Slack flow to connect user questions to Gemini for responses

Hello all.

Sorry for basic topic, this is my first work with Zapier.

 

I am struggling to create a flow that must behave this way: When a user sends a direct message (ask question) to specific user, slack must connect and send such question to Gemini (I've created a Customized Gem specialist in solving products doubts) then the reply must return to slack and the agent will directly reply to user.

 

Currently my main difficulty is: how can specifically direct the question to such Gem in Gemini, which is already set to answer specific questions.

 

Slack direct message (question)→ Gemini Prompt (gem) → slack direct message (answer)

    Hi ​@renatomsantos, welcome to the Zapier Community 👋

     

    Short answer: not exactly in the way you described, but you can get very close with a slightly different setup.

     

    Right now, Zapier’s Slack integration can’t trigger on 1:1 direct messages (DMs).

     

    However, you can build something similar using a dedicated Slack channel and the Google AI Studio (Gemini) app:

    • Have users post their questions in a specific channel (for example, #ask-gemini).

    • Use a Zap with:
      • Trigger: Slack – New Message Posted to Channel (watching that channel) or New Message Posted to Private Channel.
      • Action: Google AI Studio (Gemini) – Send Prompt or Conversation (where you put the same instructions/persona you used for your custom Gem into the “System instructions” field).
      • Action: Slack – Send Channel Message (or thread reply) to post Gemini’s answer back in Slack.
         

    You can find all of our available Slack actions and triggers here.

     

    One other important detail: Zapier can’t call a consumer “Gem” directly. Instead, you recreate that Gem’s behavior by copying its instructions into the Gemini action inside Zapier, so the API behaves like your specialist Gem.

     

    Hope this helps 😄
