Amazon V2 partial updates

Learn when Channable uses partial updates in Amazon V2, what they change, and how to check whether an item will be processed as a partial or full update.

Partial updates tell Amazon to update only the mapped, non-empty fields that Channable sends for an item.

They affect how Amazon processes and validates the update. They do not decide which fields Channable sends.

At a glance

• Partial update: used when Amazon finds an existing listing for the item

• Full update: used when no existing listing is found

• Listing requirement level: decides which data Channable sends

When Channable uses a partial update

Channable uses a partial update when the item matches an existing listing in Amazon.

If no existing listing is found, a partial update is not possible. In that case, Channable uses a full update.

What partial updates change

With a partial update, empty or unmapped attributes are not updated in that run.

If you leave a field empty, or do not map an attribute, Amazon keeps the current value.

A partial update can change both offer data and product data.

Partial updates matter because they:

• Preserve existing Amazon data for unmapped attributes

• Trigger less validation than full updates

• Still allow Channable to update mapped product and offer data

What determines which data Channable updates

The Listing requirement level determines what data Channable sends.

It doesn't affect whether Channable uses a partial or full update.

Partial and full updates only change how Amazon processes and validates the data Channable sends.

The Listing requirement level determines:

• Which attributes you see in Channable when setting up your channel

• Which validation Amazon uses during a full update

Example

Assume your item matches an existing Amazon listing.

If you run your channel with:

• price with a new value — Amazon updates price

• description unmapped — Amazon keeps the current description

• brand empty in this run — Amazon keeps the current brand

This is why a partial update can update some fields without overwriting others.

How to check whether Channable will use a partial update

1. In your Amazon channel, go to the Result step.

2. In the Channable | Your Amazon account table, check the Listing status column.

   1. If the result is anything other than No match found, Amazon found a listing for that item. Channable will use a partial update for that item in the next run.

   2. If the result is No match found, Channable will use a full update in the next run.
