Articles on: Synctrack - Estimated Delivery Date

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.

Step 2: Choose a carrier

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

Step 3: Enter credentials and pickup details

Fill in the form, then click Connect.

Shippo

API token — from your Shippo dashboard
Pickup postcode + Pickup country code (2 letters, e.g. US)
Default weight (g) — default 500
Length / Width / Height (cm) — defaults 10 / 10 / 10

Shiprocket

Email + Password — your Shiprocket login
Pickup postcode
Default weight (kg) — default 0.5
Cash on delivery (COD) — Yes for COD, No for prepaid

ShipStation

API key — from your ShipStation account
Pickup postcode + Pickup country code (required)
Pickup city / Pickup state — optional, recommended for US warehouses
Default weight (g) — default 500
Add dimensions (optional) — expand to set parcel Length / Width / Height (cm)

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.

Use a carrier in a delivery rule

Step 1: Open the rule and switch to Auto setting

Open the rule, go to the Dates tab, and switch to Auto setting under Estimated date setup.

Step 2: Pick the carrier and courier

Carrier — any connected carrier

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

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.
