# Carrier integrations

# Carrier integrations
Connect Estimated to **Shippo, Shiprocket,** or **ShipStation**, then use the carrier in your delivery rules to auto-calculate delivery days from live carrier rates instead of typing them manually. Credentials are stored encrypted, and disconnecting a carrier never deletes your delivery rules.
## Connect a carrier
### Step 1: Open Carrier integrations
Go to **General settings > Integrations**.

Click a provider card in the empty state, or click **Connect a carrier**, pick one from the **Carrier** selection.

Fill in the form, then click **Connect**.

### Step 4: Edit or disconnect
Connected carriers appear under **Your carriers**. Click **Edit settings** to update pickup or weight (the API token / password is not shown again — disconnect and reconnect to rotate it). Click **Disconnect** to remove the carrier; rules stay intact.

### Step 2: Pick the carrier and courier
* **Carrier** — any connected carrier

![](https://storage.crisp.chat/users/helpdesk/website/-/8/3/8/3/8383e5404a31c000/image_u1z844.png)

* **Select courier** — one or more courier services (UPS, FedEx, etc.)

![](https://storage.crisp.chat/users/helpdesk/website/-/8/3/8/3/8383e5404a31c000/image_16guskq.png)

* **Minimum / Maximum preparation days** — how long you need to pack the order
Minimum and Maximum delivery days are auto-filled from the carrier's live rate and are not editable.

|| Auto setting only works when a **Zipcode** condition is set in **Location conditions** — without it, the carrier has no destination to quote against.
