Use when a customer wants WhatsApp subscribers automatically synced into a Mailchimp audience. [Auto Responder Integration](/learn/chatsyncs-integrations/auto-responder/introduction) lists **Mailchimp** as one of the email marketing platforms you can connect. This page is a worked example: generating a Mailchimp API key, adding it as a profile, and pointing a bot at your Mailchimp audience. ## Step 1: Generate your Mailchimp API key In Mailchimp, click your profile icon in the top-right corner and choose **Profile**. Mailchimp top-right profile menu open, with Profile highlighted below the account name From your profile page, open **Extras → API keys** in the top navigation. Mailchimp Extras menu open with API keys highlighted, on the account's API keys page showing a Create A Key button Click **Create A Key**, give it a name so you remember what it's for later (e.g. "ChatSyncs"), and click **Generate Key**. Mailchimp Copy New API Key panel showing the generated key value and a Copy To Clipboard button Copy the key immediately — Mailchimp only shows it to you once. If you lose it, you'll need to generate a new one. ## Step 2: Add the Mailchimp profile in ChatSyncs Switch to ChatSyncs. From [Auto Responder Integration](/learn/chatsyncs-integrations/auto-responder/introduction), click **New**, select **Mailchimp** from the provider list, enter a **Profile Name**, and paste in the API key you copied in Step 1. Auto Responder API modal with Mailchimp selected in the provider list, and Profile Name and API Key fields Click **Save**. ## Step 3: Point a specific bot at your Mailchimp audience Connecting the API key only tells ChatSyncs *how* to reach your Mailchimp account — you still need to tell each individual bot *which* audience (list) to add subscribers to. Open **Bot Manager → \[your bot] → Configuration → Settings → Auto Responder**, and paste your Mailchimp audience's **list ID** into the **Mailchimp List** field. The same screen has a field for each connected platform, so you can wire up Brevo or Mautic here too. Bot Configuration Settings Auto Responder tab with Mailchimp List, Brevo List, and Mautic List fields ## Step 4: Collect the customer's email in a bot flow The list ID alone doesn't push anyone into Mailchimp — something in the conversation has to actually collect an email and hand it off. The usual way is a [Keyword Replies](/learn/chatsyncs-automation/create-a-keyword-based-whatsapp-chatbot-in-chatsyncs) flow: a trigger keyword (e.g. `sendmail`) starts the flow, and you add a **User Input Flow** block to ask for the email. Start Bot Flow node with trigger keyword sendmail, wired to a flow-blocks menu with User Input Flow highlighted Inside the User Input Flow, add a question using **Free Keyboard Input**, set its text to something like "What is your e-mail?", and set **Reply type** to **Email** — this makes ChatSyncs validate the answer actually looks like an email address before it accepts it and saves it to the `Email` system field. User Input Flow campaign named Email collect, wired to a New Question block using Free Keyboard Input, question text What is your e-mail, reply type Email, save to system field Email Once the customer answers, that's the moment ChatSyncs syncs their email into the Mailchimp list you set in Step 3 — no extra webhook or button needed. Testing it in WhatsApp looks like this: WhatsApp conversation: customer sends sendmail, bot replies What is your e-mail?, customer replies with an email address, bot replies Thanks! And on the Mailchimp side, the new contact shows up in your audience within seconds, with the source recorded as coming in through the API: Mailchimp Audience Contacts table with a newly synced contact row showing an email address, Subscribed status, and Source API See [Auto Responder Integration](/learn/chatsyncs-integrations/auto-responder/introduction) for more on how the hand-off to Mailchimp works, and [User Input Flow](/learn/chatsyncs-automation/user-input-flow-in-chatsyncs) for everything else the block can do (multiple questions, other reply types, exporting responses to CSV). ## Frequently asked Generate an API key in Mailchimp under **Extras → API keys**, then add it as a new **Mailchimp** profile under [Auto Responder Integration](/learn/chatsyncs-integrations/auto-responder/introduction). In **Bot Manager → \[your bot] → Configuration**, under the **Auto Responder** section — paste the audience's list ID into the **Mailchimp List** field. Yes — Mailchimp API access is available even on its free plan. That doesn't sync back to ChatSyncs automatically — ChatSyncs only pushes new subscriber data forward; handle unsubscribes on the Mailchimp side. ## Related Documentation * [Auto Responder Integration](/learn/chatsyncs-integrations/auto-responder/introduction) — connecting any email marketing platform and what it's used for. * [User Input Flow](/learn/chatsyncs-automation/user-input-flow-in-chatsyncs) — collecting the customer's email with validation.
