To use the MyGLS API, you must have a business contract with GLS.
If you don’t have an account yet, contact GLS sales or support via email:
it@gls-hungary.com
it@gls-slovakia.sk
it@gls-czech.com
it@gls-slovenia.com
it@gls-croatia.com
it@gls-romania.ro
Once your account is active, GLS will provide you with credentials to access their API
You will then need to request access to the API and obtain the following credentials:
API username
API password
Client number / ID
Once you have your API credentials ready:
In the app, go to Providers > Add Provider
Choose GLS as the carrier type with subtype (Select the subtype depending on where you have concluded the contract.)
Fill API credential fields:
API username
API password
Client number / ID
Map the provider to the correct shipping rates:
If you haven’t created shipping rates for GLS yet, follow this guide: Configure shipping rates for carrier integration
If you already have GLS shipping rates set up:
In the Home Delivery section, select the shipping rates that will use GLS
Assign the appropriate service, e.g. GLS Private (B2C)
If you're using pickup points, make sure to also select the relevant rates in the Pickup Points section to enable pickup point selection for customers
Set the provider as active
Save the provider
To allow customers to select a GLS Pickup point during the checkout process, you need to activate and configure the widget.
Follow the appropriate guide based on your Shopify plan.
