Mailchimp authentication

This connector is optimized for AI agents. For the data replication connector, see Mailchimp.

This page documents the authentication and configuration options for the Mailchimp agent connector.

Hosted mode (most cases)

In hosted mode, create the connector through the Airbyte Agent CLI or API, then execute operations using the CLI, Python SDK, or API. If you need a step-by-step guide, see the developer quickstart.

OAuth

This authentication method isn't available for this connector.

Token

Create a connector with Token credentials.

credentials fields you need:

Field Name	Type	Required	Description
`api_key`	`str`	Yes	Your Mailchimp API key. You can find this in your Mailchimp account under Account > Extras > API keys.

Example request:

curl -X POST "https://api.airbyte.ai/api/v1/integrations/connectors" \
  -H "Authorization: Bearer <YOUR_BEARER_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace_name": "<WORKSPACE_NAME>",
    "connector_type": "Mailchimp",
    "name": "My Mailchimp Connector",
    "credentials": {
      "api_key": "<Your Mailchimp API key. You can find this in your Mailchimp account under Account > Extras > API keys.>"
    }
  }'

Execution

After creating the connector, execute operations using the CLI, Python SDK, or API. If your Airbyte client can access multiple organizations, set the default organization with airbyte-agent organizations use, include organization_id in AirbyteAuthConfig, or include X-Organization-Id in raw API calls.

CLI

Authenticate with Airbyte:

airbyte-agent login

Create the connector. The CLI opens the hosted setup flow:

airbyte-agent connectors create --json '{
  "workspace": "<your_workspace_name>",
  "name": "mailchimp"
}'

Describe the connector to see its supported entities and actions:

airbyte-agent connectors describe --json '{
  "workspace": "<your_workspace_name>",
  "name": "mailchimp"
}'

Execute an action:

airbyte-agent connectors execute --json '{
  "workspace": "<your_workspace_name>",
  "name": "mailchimp",
  "entity": "<entity>",
  "action": "<action>",
  "params": {}
}'

Python SDK

The connect() factory returns a fully typed MailchimpConnector and reads AIRBYTE_CLIENT_ID / AIRBYTE_CLIENT_SECRET from the environment:

Open source mode

In open source mode, provide API credentials directly to the connector.

OAuth

This authentication method isn't available for this connector.

Token

credentials fields you need:

Field Name	Type	Required	Description
`api_key`	`str`	Yes	Your Mailchimp API key. You can find this in your Mailchimp account under Account > Extras > API keys.

Example request:

from airbyte_agent_sdk.connectors.mailchimp import MailchimpConnector
from airbyte_agent_sdk.connectors.mailchimp.models import MailchimpAuthConfig

connector = MailchimpConnector(
    auth_config=MailchimpAuthConfig(
        api_key="<Your Mailchimp API key. You can find this in your Mailchimp account under Account > Extras > API keys.>"
    )
)

Configuration

The Mailchimp connector also needs these configuration values to construct the base API URL.

Hosted CLI: airbyte-agent connectors create doesn't currently accept these configuration fields directly. For hosted connectors that need these values, create the connector with the hosted API replication_config, then use the CLI for describe and execute operations after creation.
Hosted API: pass these values in the connector creation replication_config.
Open source mode: provide these values with your local connector setup so the connector can build the correct API base URL.

Variable	Type	Required	Default	Description
`data_center`	`string`	Yes	us1	The data center for your Mailchimp account (e.g., us1, us2, us6)
