Hello,
To post a sales listing on eBay using the Trading API or REST Selling API, you will need to follow these general steps:
Obtain eBay API credentials: To access eBay's APIs, you will need to register as an eBay developer and obtain API credentials (e.g., App ID, Cert ID, and Dev ID).
Choose the API: Decide whether you want to use eBay's Trading API or the REST Selling API. The Trading API is the older API and offers more features, while the REST Selling API is newer and simpler to use.
Authenticate: Use your API credentials to authenticate your application with eBay.
Construct the API call: Using the API documentation, construct an API call that includes the required information for your sales listing, such as the title, description, price, and shipping details. For the REST Selling API, you will use HTTP requests (e.g., POST or GET), while for the Trading API, you will use SOAP requests.
Submit the API call: Submit the API call to eBay's servers.
Receive the response: eBay's servers will respond to your API call with a message indicating whether the listing was successfully created or if there were any errors.
Handle errors: If there were any errors, handle them appropriately, such as by retrying the API call or alerting the user.
