--------------------------------------------------

To run Postman Flows templates that use Mailchimp, you need to set up authorization between Mailchimp and Postman. You can do this by creating an API key in Mailchimp and saving the ID of your subscriber list as an environment [variable](/docs/sending-requests/variables/variables-intro/) in Postman.

Before you get started, you need:

* A [Mailchimp](https://login.mailchimp.com/signup/) account
* A Postman [environment](/docs/sending-requests/variables/managing-environments/) to run the flow

## Create a Mailchimp API key

To create a Mailchimp API key to use with Postman Flows, do the following:

1. Log in to [Mailchimp](https://login.mailchimp.com/).

2. From your account settings, navigate to **Account & billing**.

3. Select **Extras > API keys**.

4. Select **Create A Key**. Enter a name for the key, and then select **Generate Key**.

5. Copy the key you generated, excluding the suffix that contains the data center identifier. For example, if the key value is `YOUR_API_KEY-us00`, don't include `-us00`.

6. Save the key value as a variable in your Postman environment named `Mailchimp_Api_Key`.

7. Save the data center identifier as a variable in your Postman environment named `Mailchimp_DC`.

## Create an audience ID variable

To create a variable that enables the flow to access your subscriber list, do the following:

1. In the Mailchimp sidebar, select **Audience > All contacts**.

2. Select **Settings > Audience name & defaults**.

3. Copy the value for **Audience ID**.

4. Save the audience ID as a variable in your Postman environment named `Mailchimp_List_ID`.

## Next steps

After you've completed your Mailchimp configuration, you can return to the flow template or set up authorization for another integration in Postman.
