My Mailchimp connection fails with an authentication error.

Double-check that the credentials were copied without extra whitespace, that the credential has not been revoked or expired in Mailchimp, and that you connected to the correct environment (sandbox vs production). Re-issue the credential in Mailchimp and reconnect from Flows360 if the problem persists.

Flows are being throttled or returning 429 errors.

You are hitting Mailchimp's API rate limit. Reduce the frequency of polling triggers, batch updates where possible, and narrow filters so flows only fetch the records they need. Flows360 retries automatically, but sustained high volume may require redesigning the workflow.

Some records or fields are missing from Flows360.

This is almost always a permissions or scope issue. Confirm the credential used by Flows360 has read/write access to the specific objects, records, and fields you expect, then reconnect. Some Mailchimp fields are derived or admin-only and cannot be exposed via API.
