A webhook works like a messenger. When something happens in Prosp (e.g., a reply or connection request), Prosp instantly sends the details to another tool. This gives you real-time updates without needing to log into Prosp.
In simple terms, it’s Prosp’s way of pushing data out.
You might use webhooks when you want to:
Add or update a contact in your CRM when they reply
Add them to an email tool during or after a Prosp flow
Notify yourself or your team in Slack or by email about new activity
To set this up, you create a webhook in Prosp that’s triggered by a specific action. Then, you connect it to a webhook receiver in tools like Zapier or Make.com, which capture the data and send it wherever you need.
1) Pushing data OUT of Prosp with Zapier
The first thing you need to do is setup your webhook in Prosp. You can do this in:
settings > webhooks > Create a webhook
then, you need to select an event to trigger the webhook, you can choose from:
LinkedIn Message Sent
LinkedIn Voice Sent
LinkedIn Message Replied
LinkedIn Connection Sent
LinkedIn Connection Accepted
LinkedIn Comment Replied
LinkedIn InMail Message Sent
LinkedIn Comment on Last Post
LinkedIn Like on Last Post
LinkedIn Profile Visit
Tag Added to Lead
Contact Extracted (extracts leads information when a contact performs an activity through the campaign)
With your event selected, you then need a callback URL. We are going to get this from Zapier.
Head to your Zap, and select a webhook as your trigger, then select Catch Hook as the trigger event
Press continue, and then continue again
Copy the webhook URL and paste it into the callback URL in Prosp
The order now is IMPORTANT:
Click Test Webhook in Prosp
Go back to Zapier and click Test Webhook
You will then see request content from the webhook in Zapier:
Then, you're good to go! You can build out the rest of your zap using the data from Prosp
This will now be triggered on the designated action from the webhook you selected as it happens in Prosp (please allow for a small delay)
2) Pushing data OUT of Prosp with Make.com
The first thing you need to do is setup your webhook in Prosp. You can do this in:

This will now be triggered on the designated action from the webhook you selected as it happens in Prosp (please allow for a small delay)
Note: When you add a webhook, it doesn’t fire immediately. There’s a short delay before you receive it, usually after a LinkedIn reply or when your connection request is accepted.
