Set up eComm Router.
Add eComm Router to your AI app. It opens sign-in for you.
Fastest: paste this into your agent
Works in Claude Code, Codex and Claude chat. Your agent adds eComm Router, starts sign-in and confirms the connection. Already connected? Keep your current connector; it keeps working.
Set up the eComm Router MCP server (https://mcp.ecommrouter.com) so you can work on my Walmart Marketplace account. If you can run commands: in Claude Code, run "claude mcp add --transport http ecommrouter https://mcp.ecommrouter.com", then have me run /mcp to sign in. In Codex, run "codex mcp add ecommrouter --url https://mcp.ecommrouter.com", then "codex mcp login ecommrouter". If you are Claude in chat: walk me through Customize → Connectors → Add custom connector, name "eComm Router", URL https://mcp.ecommrouter.com, then Add, Connect, sign in and approve. Then call marketplace_overview to confirm and show me the welcome. Never ask me for Walmart API keys in chat. I enter them only in the secure eComm Router browser form.

Sign in to eComm RouterConnect your Walmart Marketplace account
Open your account and use the secure connection form. eComm Router verifies the seller and environment before you consent to seller access.
Use your own personal Walmart API keys: the Client ID and Client Secret. Do not paste them into chat or email. Connecting keys does not expand an existing client grant.
Open secure connection formContinue in Claude
Return to Claude after authorization. Ask:
“What can eComm Router help me do?”
Start with setup and connection status. Seller tasks depend on implemented actions, your current grant, Walmart permissions, and program eligibility.
No account data is imported just by signing in.
Where do I get my API keys?
Your Walmart Marketplace seller account must be approved to sell first.
- Open Walmart's Developer Portal at developer.walmart.com. Sign in with your Walmart Marketplace seller login.
- Open My Account.
- Find your personal key pair. It has a lock icon next to it.
- Copy its Client ID and Client Secret.
- Paste both into the secure eComm Router key form. Choose Production or Sandbox to match the keys.
For sandbox keys, follow Walmart's sandbox guide. Walmart’s sandbox guide ↗
Never paste keys into Claude, Codex, chat or email.
What can my client access?
The consent screen lists its exact permissions. Setup-only access cannot read seller data or perform seller changes. Each client needs a separate grant, which you can revoke from your account.
eComm Router retains redacted tool requests and outcomes for support, not your full conversation. Data retention and deletion.
