Mercado Ads Data Extractor

Vern's Mercado Ads extractor imports a new user's advertising data — brand advertisers, brand campaigns, brand campaigns metrics, and brand items — into your product through a single managed migration, handling Mercado Ads's auth, pagination, and rate limits for you. It's built for teams onboarding customers off Mercado Ads who want their data in your app from day one.

Objects Vern extracts

Vern extracts the full set of queryable Mercado Ads objects (17 total), including: Brand Advertisers, Brand Campaigns, Brand Campaigns Metrics, Brand Items, Brand Keywords, Brand Keywords Metrics, Display Advertisers, Display Campaigns, Display Campaigns Metrics, Display Creatives, Display Line Items, Display Line Items Metrics, Product Advertisers, Product Campaigns, Product Campaigns Metrics, Product Items, and Product Items Metrics. 6 of these support incremental change tracking, so syncs pull only what changed.

Output schema

Normalized JSON per object with referential keys preserved, so the relationships between your user's records survive the import. Timestamps are returned in ISO 8601. Delivered as JSON or CSV, or loaded straight into your own application database or pushed to your API — whatever your product expects.

Where it can land

Your own application database (Postgres, MySQL), a direct push to your API or webhook, or JSON/CSV files, plus another advertising system (Amazon Ads, Apple Ads, AWIN Advertiser) when a user is switching tools.

Source details

Built for the source type shown above, with extractor content refreshed from the collection record.

Managed by Vern

The details you normally have to build yourself.

Authentication

OAuth 2.0 (Authorization Code flow). Your new user authorizes Mercado Ads once during onboarding — their credentials never touch your code. Mercado Ads access tokens are short-lived and refresh tokens roll on the provider's own schedule, so Vern manages the full token lifecycle and refresh and the import never drops midway.

Pagination

Vern detects and handles Mercado Ads's paging model (cursor, page-number, or offset) internally and returns one consistent, de-duplicated result set — so you import a user's complete data without ever managing page tokens.

Rate limits and gotchas

Mercado Ads enforces its own API rate limits. Vern queues and throttles requests internally so importing a new user's data never trips a 429 — even on a large account.

OAuth-based sources expire access tokens frequently and require a working refresh flow — a dropped refresh is the most common cause of a half-finished import. Vern owns the refresh loop so a new user's onboarding completes even on a long extraction.

API quickstart

1. Create a migration for Mercado Ads
curl -X POST https://app.vern.so/api/v1/migrations \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "name": "Mercado Ads → Postgres", "source": "Mercado Ads" }'
→ { "migration_id": "mig_..." }
2. Generate the extraction recipe (pulls live via the Mercado Ads API)
curl -X POST https://app.vern.so/api/v1/migrations/$MIGRATION_ID/runs \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "kind": "generate", "extract_via_api": true }'
3. Run the approved extraction
curl -X POST https://app.vern.so/api/v1/migrations/$MIGRATION_ID/runs \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "kind": "execute" }'
4. Download the normalized CSV export
curl https://app.vern.so/api/v1/migrations/$MIGRATION_ID/exports/{template} \
  -H "x-api-key: $VERN_API_KEY" -o mercado-ads_export.csv

A cleaner way to extract without rebuilding source-specific plumbing.

Common questions

Can I keep a user's Mercado Ads data in sync after the first import? Yes — 6 Mercado Ads objects support incremental change tracking, so after the first full import Vern pulls only what changed on re-run.

Can I move a user from Mercado Ads to Amazon Ads? Yes — Vern normalizes the Mercado Ads data model into typed tables that map cleanly onto Amazon Ads and into your own product.

What does it cost to read the Mercado Ads API? Mercado Ads's own API access follows Mercado Ads's pricing/plan; Vern is billed separately per import. Check Mercado Ads's developer docs for their current limits.
