I'm a seller on Walmart's market and I'm currently trying to automate my ad placements using Walmart's API. I've successfully obtained my own Client ID and Client Secret from the backend and have also managed to secure an access token via /v3/token API endpoint.
However, I noticed that in order to call the advertising API, I require both WM_CONSUMER.ID and WM_SEC.AUTH_SIGNATURE. I'm at a loss as to where and how I can obtain these two pieces of information.
As a seller, am I able to access these? If so, could you kindly guide me through.
I used the provided JAR package to obtain the WM_SEC.AUTH_SIGNATURE, but I realized that I'm missing the Consumer ID and Private Key. I tried using the Client ID and Client Secret for authentication, but it failed.
Do I need to obtain the Consumer ID and Private Key first? I'm not sure how to obtain them. I looked at other questions, and it was suggested to obtain them through the Affiliate Marketing API. However, I'm not sure if this applies to Advertising as well. I also noticed that this seems to be intended for Affiliates, Developers, and Partners. I'm unsure if it is applicable to me as a third-party marketplace seller.
