How to Send Ninja Forms Submissions to Slack

Slack is a messaging platform. Form submissions can trigger instant notifications. Every Ninja Forms submission should flow into Slack without manual effort. This guide shows how to set that up in five minutes.

The direct approach

AFI delivers form data straight from WordPress to Slack. No third-party cloud, no per-task fees, and every request is logged for troubleshooting.

What you will need

• A WordPress site with Ninja Forms installed and at least one form.
• A Slack account.
• The Advanced Form Integration plugin (free from WordPress.org).

Connect Slack to AFI

Slack uses OAuth 2.0 for authentication. In AFI → Settings → Slack, click Authorize and grant access. This is a one-time step.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it Ninja Forms to Slack.

2. Pick your trigger

Select Ninja Forms as the form provider and choose the form you want to connect. AFI detects the fields automatically.

3. Select Slack as the destination

Choose Slack from the platform dropdown and pick Send Message. This sends a message to a Slack channel.

4. Map fields

Match each Slack field on the left to the corresponding Ninja Forms field on the right. You can also use smart tags like {{_submission_date}} and {{utm_source}}.

5. Add conditions if needed

Only want to send certain submissions? Set up a conditional rule based on any form field value.

6. Save and test

Click Save Integration. Fill out your Ninja form and submit. Check Slack to confirm the data arrived. If anything looks wrong, open AFI → Log to see the exact request and response.

Free vs Pro

The free version maps message text to Slack with unlimited submissions. Pro adds channel selection via webhook. No per-submission fees on any plan.

Frequently asked questions

Do I need coding skills?

No. Everything is configured through a visual interface, including field mapping.

Will adding this slow down my form?

No. AFI sends data to the destination after the form submission completes. Your visitors see the normal success message without any delay.

Can I connect multiple Ninja Forms?

Yes. Create a separate integration for each form, or send one form to multiple platforms.
