Steps 3 and 4 of the PROSP wizard decide who owns which leads and whether replies arrive at all. Both are quick, but step 4 has a trap.

**With PlusVibe both are simpler:** assigning mailboxes is optional, unassigned replies go to the workspace owner, and inDeal registers the webhook in PlusVibe itself. The steps are in [Connecting PlusVibe](https://success.indeal.ai/hc/indeal/articles/connecting-plusvibe).

## Step 3: assign senders

The note reads: **Assign each PROSP sender to a team member. Replies from that sender are attributed to that member as owner.**

1. inDeal fetches the senders from PROSP; meanwhile it reads **Fetching senders …**
2. Pick the responsible person per sender via **Choose member**.
3. An assigned sender is then marked **Assigned**.

**Why this matters:** the assignment decides who incoming leads belong to. That determines who sees them in [**Open leads** ↗](https://app.indeal.ai/leads/open) at all, whose numbers on [**Home** ↗](https://app.indeal.ai/) they affect, and who receives the workflow notifications.

As long as a sender is unassigned you cannot continue; you see **Assign every open sender to continue.**

### If a sender shows as a conflict

If a sender shows **Conflict**, the note reads: **This sender is already taken in another workspace and cannot be assigned here. Your agency will sort this out. You can continue anyway.**

Each sender address belongs to exactly one account. Continue and report the case to your agency.

If there are no senders at all, it reads **There are no senders for this connection yet. You can continue.**

## Step 4: set up the webhook

The webhook is the line replies travel down to reach inDeal instantly. Without it, leads are still imported but no replies are delivered - and so no workflows run.

The wizard shows a **Callback URL** and the **Copy** button; after the click it briefly reads **Copied**.

The five steps as the product states them:

1. **In PROSP, open Settings, Webhooks, Create a webhook.**
2. **Paste the copied URL as the Callback URL.**
3. **Select "LinkedIn Message Replied" as the event.**
4. **Press Test Webhook.**
5. **Then press Continue so the webhook is saved.**

The **Open PROSP webhooks** button takes you straight to the right place.

### The trap the product highlights itself

**Important: step 5 is required. If you stop after the test, you have only tested it but saved nothing.**

That is the most common mistake during setup. The test reports success, everything looks right, and afterwards no webhook exists. Make sure you press **Continue** in PROSP.

### How you know it worked

While inDeal waits, it reads **Waiting for the first connection from PROSP …** As soon as the first message arrives, it changes to **Connected. Leads are flowing now.**

The connection status then jumps from **Setup pending** to **Active**.

You can close the window at any time: **You can close anytime and resume setup later.**

## If nothing arrives

Check in this order:

1. **Was Continue pressed?** Without that step there is no saved webhook in PROSP.
2. **Is the event right?** It has to be **LinkedIn Message Replied**.
3. **Is the URL right?** Take it unchanged from inDeal, without truncating it.
4. **Does the status read Active?** If not, the first message from PROSP is still missing.

Two fields on the connection card help: **Last event** shows when something last arrived, **Last sync** when the last sync ran. If both are empty, nothing has ever come in.
