No code required to automate data flow with built in triggers and actions
Keep Mailchimp lists and GHL contact records in sync in real time or on a schedule
Unify reporting with a single view of contacts, campaigns, and activities across both platforms
Key elements include API endpoints for reading and updating contacts, authentication flows, triggers, actions, and how field mapping works between Mailchimp and the GHL Contacts API
A specific URL used to perform a defined operation within an API
Process to verify identity and authorize API requests to access data
A URL that receives event notifications from an external service in real time
An event that starts a workflow or action in the integration
Use event triggers from Mailchimp to push updates to GHL in real time, ensuring campaigns reflect the latest contact activity.
Automatically map Mailchimp list segments to GHL contact groups and adjust campaigns accordingly.
Create automated journeys that trigger in GHL based on Mailchimp engagement and stage transitions.
Register API credentials in both services and configure the scopes for read and write access, then generate tokens.
Match Mailchimp fields such as email and list id to GHL contact fields like email and contactId to ensure clean syncing.
Run a test sync, verify data integrity, fix any mapping issues, and activate the integration.
No code is required to set up the Mailchimp to GHL integration. Use the built in triggers and actions to automate common tasks. Start by authenticating both services, then map the key fields and enable the workflow. If you run into issues, check the token scopes and ensure the API keys are active.
You can sync core contact data such as email, first name, last name, phone, and custom fields. Mailchimp lists and segments can be mirrored in GHL as contact tags or groups for targeted campaigns. Field mappings can be adjusted in the integration settings.
Sync frequency can be real time or scheduled. Real time updates occur when events fire in Mailchimp or GHL, while a nightly or hourly schedule can be configured for batch processing.
Yes, you can customize field mappings to control which data moves between Mailchimp and GHL. Use merge fields and custom fields to align your data models.
Historical data can be imported in batches. Start with the most recent records and backfill as needed. Maintain deduplication rules to avoid duplicates.
Common endpoints include read endpoints for contacts and notes, as well as write endpoints to create or update records. Always verify authentication and scopes before making calls.
If authentication fails, re-check your API keys, OAuth tokens, and scope access. Ensure the accounts are linked and tokens are not expired. Review error codes returned by the API for guidance.
Due to high volume, we will be upgrading our server soon!
