Walmart is making "delegated access" available to all sellers, meaning that they can go to the Walmart Developer portal and retrieve different keys for every integration.
Step 1: Go to Developer.Walmart.com. Do not type in www before this address, or else it will not work.
From the dropdown below your username, select "API Keys".
Step 2: Scroll all the way down to Production Keys for Solution Providers (Delegated Access). Do not go to Sandbox.
Add ecomdash as a Solution Provider from the dropdown and set all permissions as “Full Access”.
Step 3: If the options are limited to “No Access” or “View Only”, select "View Only".
Some accounts are in "read only" access and some accounts have "admin" accounts. People with "read only" accounts will see two options.
Select Full Access if all these options are visible.
Step 4: Generate your keys into Ecomdash.
Click the blue text that reads "API keys".
There should be a black pop up that shows the keys, you will want to enter those keys into ecomdash.
