Connect with Shipping API -- 2

We are a German eCommerce that ships its articles to China. We are currently working with several shipping providers such as DHL and Hermes. As a new project, we want to integrate the Dutch Post ("NL Post") as a shipping provider for China. Can you send us a time estimate how long it would take to integrate? We need to integrate 2 APIs. First API ("Barcode Webservice") generates the barcode for identification of the package. Second API ("Labelling webservice") generates the shipping label and the PDF customs documents (C23). We will only send packages to China with NL Post (no shipping to Germany). They have good documentation online: [login to view URL] [login to view URL] [login to view URL] (example for labelling webservice to China) Barcode Webservice The service returns the barcode to identify the package. The barcode is required by the labelling webservice. We want to store the barcode in the order field for tracking number. We will only do GlobalPack shipments. CustomerCode, CustomerNumber, Type, Range, API credentials: -> You will receive this from us Serie: -> The Serie must always be 0000-9999 for use with GlobalPack to be able to generate a unique number for you. Labelling Webservice We want to add a button to order overview and order detail view, that generates shipping label and customs document. We want to keep the exisiting bordergurus button - we want to have the choice to print NL post or BorderGurus. The order information is sent via API. The API responds with shipping label and customs document. We want to store shipping label and customs document in the order. Our logistics partner will access the documents. We only need to integrate the fields that are mandatory for china. For each product, we need to include the shop URL.

If the job is good we will continue contacting you for further projects.
