Getting Started with Mercado Libre Ads: Complete Authentication Guide for Sellers

Authentication is more than a login. It determines which advertisers you can manage, which products you can activate, and which currencies appear throughout Amplasa.

• Automatic detection of Product Ads and Display Ads permissions.
• Workspace presets that match your Mercado Libre sites and currencies.
• Guardrails that surface missing scopes before campaign creation.

1. Visit the Amplasa sign-in page and choose “Connect with Mercado Libre”.
2. Accept the OAuth request and verify the advertiser accounts that appear in the selector.
3. Pick your starting workspace, including product type and marketplace site.
4. Validate connectivity from the status banner before inviting collaborators.

Most sellers complete the flow in under three minutes and can immediately explore campaign data.

• Missing Product Ads: enable the product in Mercado Libre publicidad > Product Ads and retry the connection.
• Access denied for client accounts: request admin access or ask the brand owner to grant agency permissions.
• Unexpected currency: confirm the advertiser’s site (e.g., MLA vs MLM) and adjust the workspace selection.

• Use individual Mercado Libre credentials for every collaborator; avoid shared logins.
• Review the audit trail inside Amplasa to confirm who connected or revoked access.
• Rotate access quarterly by asking inactive collaborators to re-authenticate.

Following these routines keeps your advertising perimeter tight while still moving quickly.
