Create a New Data Flow​

  1. To create a new data flow, navigate to the Integrate section, and click the New Data Flow button. Then, select the desired flow type from the list, and click the Create button.

  2. Select the Walmart connector tile from the list of available connectors. Then, select the credential that will be used to connect to the Walmart instance, and click Next; or, create a new Walmart credential for use in this flow.

  3. In Nexla, Walmart data sources can be created using pre-built endpoint templates, which expedite source setup for common Walmart endpoints. Each template is designed specifically for the corresponding Walmart endpoint, making source configuration easy and efficient.
    • To configure this source using a template, follow the instructions in Configure Using a Template.

Walmart sources can also be configured manually, allowing you to ingest data from Walmart endpoints not included in the pre-built templates or apply further customizations to exactly suit your needs.
• To configure this source manually, follow the instructions in Configure Manually.

Configure Using a Template​

Nexla provides pre-built templates that can be used to rapidly configure data sources to ingest data from common Walmart endpoints. Each template is designed specifically for the corresponding Walmart endpoint, making data source setup easy and efficient.

Endpoint Settings​

  • Select the endpoint from which this source will fetch data from the Endpoint pulldown menu. Available endpoint templates are listed in the expandable boxes below. Click on an endpoint to see more information about it and how to configure your data source for this endpoint.

    Get all orders

    This endpoint template retrieves a list of all orders from your Walmart account. Use this template when you need to access order information, order details, or order metadata for analysis, reporting, or integration purposes.

    • Enter the Created Start Date in the Created Start Date field. This should be the start date for filtering orders by creation date. The Created Start Date determines which orders will be retrieved. You can use Nexla macros like `{now}`, `{now - 70}` etc. The default value is `{now-70}` (70 days ago).
    • Enter the Ship Node Type in the Ship Node Type field. This should be a list of Ship Node values that determines the fulfillment type for the orders. The Ship Node Type determines which orders will be retrieved. You can select from the available options: Seller Fulfilled (SellerFulfilled), WFS Fulfilled (WFSFulfilled), or 3PL Fulfilled (3PLFulfilled). The default value is SellerFulfilled.

    This endpoint returns a list of all orders from your Walmart account, including order IDs, order details, shipping information, and other order metadata. The endpoint uses a two-step process: first, it obtains an access token using your credentials, then it retrieves orders using that token. The endpoint uses link header pagination to handle large result sets efficiently. Nexla will automatically follow the pagination to fetch subsequent pages of order data.

    For detailed information about orders, API response structures, pagination, and available order data, see the Walmart API documentation.

    Get all returns

    This endpoint template retrieves a list of all returns from your Walmart account. Use this template when you need to access return information, return details, or return metadata for analysis, reporting, or integration purposes.

    • This endpoint automatically retrieves a list of all returns from your Walmart account. No additional configuration is required beyond selecting this endpoint template. The endpoint uses a two-step process: first, it obtains an access token using your credentials, then it retrieves returns using that token.

    This endpoint returns a list of all returns from your Walmart account, including return IDs, return details, refund information, and other return metadata. The endpoint uses a two-step process: first, it obtains an access token using your credentials, then it retrieves returns using that token. The endpoint uses link header pagination to handle large result sets efficiently. Nexla will automatically follow the pagination to fetch subsequent pages of return data.

    For detailed information about returns, API response structures, pagination, and available return data, see the Walmart API documentation.

Endpoint Testing​

Once the selected endpoint template has been configured, Nexla can retrieve a sample of the data that will be fetched according to the current settings. This allows users to verify that the source is configured correctly before saving.

  • To test the current endpoint configuration, click the Test button to the right of the endpoint selection menu. Sample data will be fetched & displayed in the Endpoint Test Result panel on the right.

  • If the sample data is not as expected, review the selected endpoint and associated settings, and make any necessary adjustments. Then, click the Test button again, and check the sample data to ensure that the correct information is displayed.

Configure Manually​

Walmart data sources can be manually configured to ingest data from any valid Walmart API endpoint. Manual configuration provides maximum flexibility for accessing endpoints not covered by pre-built templates or when you need custom API configurations.

With manual configuration, you can also create more complex Walmart sources, such as sources that use chained API calls to fetch data from multiple endpoints or sources that require custom authentication headers or request parameters.

Walmart API endpoints typically require a two-step authentication process: first obtaining an access token, then using that token to make API calls. Manual configuration may require setting up chained API calls to handle this authentication flow.

API Method​

  1. To manually configure this source, select the Advanced tab at the top of the configuration screen.

  2. Select the API method that will be used for calls to the Walmart API from the Method pulldown menu. The most common methods are:

    • GET: For retrieving data from the API (most common for Walmart data sources)
    • POST: For token generation or data submission

API Endpoint URL​

  1. Enter the URL of the Walmart API endpoint from which this source will fetch data in the Set API URL field. This should be the complete URL including the protocol (https://) and any required path parameters.

Ensure the API endpoint URL is correct and accessible with your current credentials. You can test the endpoint using the Test button after configuring the URL. Note that Walmart API endpoints may require an access token obtained through a separate authentication call.

Path to Data​

If only a subset of the data that will be returned by API endpoint is needed, you can designate the part(s) of the response that should be included in the Nexset(s) produced from this source by specifying the path to the relevant data within the response. This is particularly useful when API responses contain metadata, pagination information, or other data that you don't need for your analysis.

For example, when a request call is used to fetch a list of orders, the API will typically return an array of order records, along with metadata, in the response. By entering the path to the relevant data, you can configure Nexla to treat each element of the returned array as a record.

Path to Data is essential when Walmart API responses have nested structures. Without specifying the correct path, Nexla might not be able to properly parse and organize your data into usable records.

  • To specify which data should be treated as relevant in responses from this source, enter the path to the relevant data in the Set Path to Data in Response field.

    • For responses in JSON format enter the JSON path that points to the object or array that should be treated as relevant data. JSON paths use dot notation (e.g., $.list.elements.order[*] to access an array of orders within a response object).

    • For responses in XML format, enter the XPath that points to the object/array containing relevant data. XPath uses slash notation (e.g., /response/orders/order to access order elements within an orders element).

    Path to Data Example:

    If the Walmart API response is in JSON format and includes a nested structure like list.elements.order that contains the relevant data, the path to the response would be entered as $.list.elements.order[*].

Autogenerate Path Suggestions​

Nexla can also autogenerate data path suggestions based on the response from the API endpoint. These suggested paths can be used as-is or modified to exactly suit your needs.

  • To use this feature, click the Test button next to the Set API URL field to fetch a sample response from the API endpoint. Suggested data paths generated based on the content & format of the response will be displayed in the Suggestions box below the Set Path to Data in Response field.

  • Click on a suggestion to automatically populate the Set Path to Data in Response field with the corresponding path. The populated path can be modified directly within the field if further customization is needed.

Endpoint Testing (Manual Configuration)​

After configuring all settings for the selected endpoint, Nexla can retrieve a sample of the data that will be fetched according to the current configuration. This allows users to verify that the source is configured correctly before saving.

  • To test the current endpoint configuration, click the Test button to the right of the endpoint selection menu. Sample data will be fetched & displayed in the Endpoint Test Result panel on the right.

  • If the sample data is not as expected, review the selected endpoint and associated settings, and make any necessary adjustments. Then, click the Test button again, and check the sample data to ensure that the correct information is displayed.

Save & Activate the Source​

  1. Once all of the relevant steps in the above sections have been completed, click the Create button in the upper right corner of the screen to save and create the new Walmart data source. Nexla will now begin ingesting data from the configured endpoint and will organize any data that it finds into one or more Nexsets.
