Form.io powers forms inside portals and custom apps, from claim forms to onboarding checklists. FlowMattic catches each new submission and tells the right people in Slack, with nested data parsed into readable lines. Developers stop writing their own notification code, and operations teams see submissions without opening the Form.io portal.

You build this in the FlowMattic workflow builder on your own site. See the setup steps
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateOperations staff see each submission in Slack with the fields they need to act, without logging into the Form.io portal or building an email notice in code.

View the template Form.io data grids and containers send nested values. A JSON Parser pulls out the rows you want, so the Slack message reads as a list instead of raw data.

A Router looks at a select field such as request type and posts each submission to the team channel that handles it, so nobody triages by hand.

For internal forms such as purchase or leave requests, the manager named in the form gets a direct message, and Human in the Loop holds the run until the request is approved.

Forms that collect health, HR or payment details post to a private channel with a short summary, so only the people cleared to see them get the notice.

When a client completes the onboarding form, Slack creates a channel named after them and sets its topic, giving the account team one place for that client.

At the end, every new submission on your Form.io form is posted to the Slack channel you choose.
In FlowMattic, open Connects and add a Slack connection for the workspace your team uses.
Create a workflow with the Form.io New Form Submission trigger and follow the steps shown to send your form's submissions to it.
Submit the form once with realistic values so every component key is captured as a field.
Add Send Channel Message, choose the channel and map the fields that matter. Test the step and switch the workflow on.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Form.io and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Developers building on Form.io can leave chat alerts to a workflow that the operations team can read and change on the canvas.
Submissions pass through your own WordPress site on the way to Slack, and you choose exactly which fields appear in the message.
FlowMattic has no per-run pricing, so a high-volume portal form costs the same to automate as a contact form.
Connect Slack in FlowMattic, start a workflow with the Form.io New Form Submission trigger, submit a test entry and add a Send Channel Message step with the fields you want. Test it and switch the workflow on.
Yes. Create one workflow per form, each with its own channel, or use one workflow and a Router that checks the form name or a field and posts to the right channel.
Add a JSON Parser step to read the grid, or an Iterator to go through each row. Build the lines with Text Formatter and use the result in the message text.
Yes. Send the manager a direct message with the details, then add a Human in the Loop step. It pauses the workflow until someone approves or rejects the request, and the steps after it continue from that decision.
