Walmart Marketplace API

API Documentation Link

Configuration Parameters

Any instance where an entry in the below configuration has a leading $ represents a parameter that needs to be replaced with a static value.

Parameters in this document:

  • $client_id and $client_secret - The tokens associated with an Authenticated User in Walmart, which can be exchanged for the access token that will be used to make API calls. You can find your Client ID and Client Secret here.
  • $encoded_auth - In order to utilize the Client ID and Client Secret to access the Walmart API, it must be added to the Refresh Access Token process as a Base64-encoded value. To get this, within your computer's terminal, enter the following string:
    echo -n '$client_id:$client_secret' | base64. The result will be the value to use for this parameter. If you run into any problems running the above string in the terminal, you can also find online resources for generating a Base64-encoded value, or reach out to our Support Team and we'd be happy to assist in generating this value.
  • $endpoint - The endpoint, or data, that you would like to ingest into Panoply. The value that should be used here can be found in the API Resources table below.
  • $version - The version of the API can be found in the Walmart documentation for a given resource, and will be given as v# (e.g. v2, v3, etc.).
  • $limit - The limit represents the number of records returned by the API per page.
  • $pagination_key - The field that will be used for paginating results in the API.
  • $data_key - The Data Key represents the path to the data in response object.
  • $incremental_key - The Incremental Key represents the column that will be used to collect only new records in subsequent collections.
  • $primary key - Primary keys are used to ensure the uniqueness of the rows in a table. The Primary Key is comprised of one or more columns that can be used to identify the row in the data warehouse. The process guarantees that no two rows have the same value in their primary key.

API Resources

For a list of API Resources available for the Walmart Marketplace API, please refer to the list of endpoints found here. We have also provided a list below with endpoints that we have successfully connected to in the Panoply platform to provide integration details that are necessary and utilized below. If an endpoint that you would like to ingest does not appear in this list, please reach out to our Support Team and we'd be happy to assist in getting that connected!

Connector configuration

  • Base url:$version/$endpoint
  • Method: GET
URL Parameters

All resources utilize the limit=$limit URL parameter, however additional parameters can be used in addition to this and can be found in the links above for each resource. For example, if you only want to collect Published Items that are in New condition, the following would be the URL Parameters entry:

To find additional parameters available for a given resource, visit the link for the resource provided above in the API Resources section.

  • Headers: {"WM_QOS.CORRELATION_ID":"Panoply","WM_SVC.NAME":"Walmart Marketplace","Accept":"application/json"}

Destination Table naming convention is ultimately up to you as the data owner. One common structure used for this API is concatentating "walmart_" and the resource being ingested. For example, when ingesting the Orders resource, the destination table name would be walmart_orders.
