Connect your BigCommerce store with ProductPolish via the V2/V3 API. You create an API account and need the Store Hash, Access Token, and Client ID.

Step-by-step guide

Open BigCommerce Admin

Log in to your BigCommerce Admin at https://store-xxxxx.mybigcommerce.com/manage.

Find your Store Hash

Your Store Hash is in the URL of your admin dashboard:

https://store-abc123xyz.mybigcommerce.com/manage/dashboard

The part between store- and .mybigcommerce.com is your Store Hash.

3

Create API account

Navigate to: Settings→Advanced→API Accounts→Create account

Select "Create V2/V3 API token".

4

Configure API permissions

Fill in the form:

  • Name: ProductPolish

Under OAuth Scopes, enable at least:

  • Products → modify
  • Content → modify (for images)

Click "Save".

You can also set all scopes to "modify" to avoid restrictions later.
5

Copy credentials

After saving, you will see:

  • Client ID
  • Client Secret
  • Access Token
The Access Token is only shown once! Copy it immediately. The Client ID is always visible under Settings → API Accounts.
BigCommerce also offers a .txt file download containing all credentials. Save it securely.
6

Enter in ProductPolish

Go in ProductPolish to Dashboard→Integrations→New connection.

  1. Select BigCommerce as the platform
  2. Enter your Store Hash
  3. Paste the Access Token
  4. Paste the Client ID
  5. Click "Save connection"
Done! ProductPolish uses the BigCommerce V3 Catalog API to create and edit products in your store.

Good to know

  • API versions: ProductPolish primarily uses the V3 Catalog API.
  • Rate limits: BigCommerce allows approx. 150 requests per second for OAuth tokens.
  • Images: Product images are uploaded via the V3 Product Images API.
  • SEO: Meta title and meta description are automatically written to the BigCommerce SEO fields.
  • Channels: Products are created in your default channel by default.

Common issues

"API Accounts" menu not visible

Only the store owner can create API accounts. Ask the owner to create the account for you.

"401" or "403" errors

Check that the Access Token is correct and the required scopes (Products: modify) are set.
