Frequently Asked Questions

How do I connect Flexmail and Slack?

Sign up for a free viaSocket account, then authorize both your Flexmail and Slack 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 Flexmail and Slack 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 Flexmail to Slack?

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

Can the integration run in both directions?

Yes. You can set up a workflow where Flexmail triggers actions in Slack, and a separate workflow where Slack triggers actions in Flexmail. 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 Flexmail and Slack. 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 Flexmail and Slack integration is built through a visual, point-and-click interface. Code blocks are available if you want them, but they are never required.
