Frequently Asked Questions

How do I connect 1Lookup and MailChimp?

Sign up for a free viaSocket account, then authorize both your 1Lookup and MailChimp accounts. From there, pick a trigger in one app and an action in the other. Your first workflow can be live in under five minutes.

Does this integration work in real time?

Yes. viaSocket uses instant triggers where available, so data moves between 1Lookup and MailChimp as soon as the event happens. Scheduled polling triggers run at a maximum interval of 15 minutes.

Can I control which data gets sent from 1Lookup to MailChimp?

Yes. You can map specific fields, apply filters to skip records that do not match your conditions, and transform values before they reach MailChimp. No coding required.

Can the integration run in both directions?

Yes. You can set up a workflow where 1Lookup triggers actions in MailChimp, and a separate workflow where MailChimp triggers actions in 1Lookup. Both run independently and in real time.

What happens if a step in the workflow fails?

viaSocket logs every run so you can see exactly what succeeded and what failed. Failed tasks can be retried from the dashboard without re-configuring the workflow.

Is viaSocket free to use?

Yes, there is a free plan that covers basic workflows between 1Lookup and MailChimp. Paid plans unlock higher task limits, faster polling, and advanced features like multi-step workflows and conditional logic.

Do I need to know how to code to set this up?

No. The entire 1Lookup and MailChimp integration is built through a visual, point-and-click interface. Code blocks are available if you want them, but they are never required.
