Webhook Connect ships in the Pro Pack and is the connection to reach for when the app you need has no card of its own. Nearly every modern tool can send a webhook, and nearly every automation tool can receive one, so this card works with almost anything.
Connecting it:

- Open the Connections tab and find Webhook Connect.
- Click Connect. WP Sync makes your private Inbound Webhook URL.
- Optionally add Outbound Targets, one per line as Label | https://url.
- Click Save Changes.
As a source:

Paste the Inbound Webhook URL into the other system's webhook or notification settings. Every POST that arrives becomes a contact fed into the bridges whose source is Webhook Connect, Inbound Webhook (catch a POST).
- Send JSON, or a normal form post.
- The email is picked up from any field holding a valid address, such as email, contact_email or user.email.
- First and last names are read from the usual field names.
- Every other field is kept and can be used as a token, including nested fields written with dots.
As a destination:
Each outbound target you listed becomes a destination named Outbound, then your label. Each contact is sent there as a JSON POST containing email, first_name, last_name and site, plus the custom fields, tags and all the source's fields. Zapier, Make, n8n, a custom script or an internal tool can take it from there.
Why the inbound URL is safe:
The URL contains a long private token. A request with the wrong token is refused. Keep the URL private like a password.
What the sender gets back:
A successful POST is answered with ok and the number of bridges that ran. A POST with no valid email anywhere in it is answered with a short message saying so, which helps when setting up the other side.
Step by step: a quiz tool to ActiveCampaign:
yoursite.com runs a quiz on its website. The quiz tool can send results to a webhook.
- Connect Webhook Connect and copy the Inbound Webhook URL.
- Paste it into the quiz tool's webhook setting and send a test result.
- Create a bridge named Website quiz leads to ActiveCampaign, with Webhook Connect, Inbound Webhook (catch a POST) as the source.
- Add ActiveCampaign, Newsletter, with the tag Quiz lead and the custom field Lead Source set to Website quiz.
- Add Google Sheets Connect, Lead tracker, to keep every answer.
- Click Create Bridge.
After the first real result arrives, the quiz's fields, such as quiz_result, score and utm_source, appear as token chips in the builder.
Sending to Zapier, Make or n8n:
- In the automation tool, create a scenario or zap that starts with a webhook trigger, and copy its URL.
- On the Webhook Connect card, click Edit Settings and add a line such as Zapier new buyers | followed by that URL.
- Click Save Changes.
- In the bridge builder, the destination list now includes Outbound, then Zapier new buyers.
- Send a live test so the automation tool learns the fields.
What an outbound POST contains:
- email, first_name and last_name, after your field mapping.
- site, your site's address.
- custom_fields and tags from the destination's mapping.
- all_fields, every simple field the source sent, with sensitive keys removed.
Several senders, one URL:
The inbound URL is shared by every bridge whose source is Webhook Connect. Each POST runs all of those bridges, so use a filter on each bridge, or one bridge with several destinations, to decide where each sender's contacts go.
Tips:
- Send one test POST before building the bridge, so the field names are known.
- For an app that has its own card, use the card. It knows that app's events and fields.
