New Features

Redshift Data Warehouse Support

Weld now supports Amazon Redshift as a destination data warehouse — both Serverless and Provisioned Cluster deployments. You can now land synced data directly into Redshift alongside BigQuery, Snowflake, and Postgres.

Primary Key Visibility on Incremental Syncs

Primary key columns are now displayed in the UI for most incremental sync streams. Primary key columns are locked to prevent accidental filtering or hashing transformations, protecting downstream data integrity.

Multi Ad Account Backfill (Beta)

A new backfill feature for Google Ads, Google Analytics, and Microsoft Ads that enables syncing historical data across multiple ad accounts simultaneously. Currently in beta testing with select customers.

Zero-Config Integrations

Integrations that require no authentication (such as Weld Data and Forex) can now be set up instantly with no blank configuration forms.

Amazon Selling Partner: New Authentication Method

We are updating the authentication method for the Amazon Selling Partner connector. Going forward, each connection must authenticate using credentials from your own Selling Partner API (SP-API) application instead of Weld's shared OAuth.

New required fields: Refresh Token, Client ID, and Client Secret from your SP-API application.

  • Effective now — all new Amazon Selling Partner connections use the new authentication method.
  • By April 30, 2026 — all existing connections must be migrated.

For step-by-step migration instructions, see the full release notes or the Amazon Selling Partner connector documentation.

Connector Updates

Major reliability and scalability improvements:

  • Universal Soft Deletes: Soft deletes are now enabled for all time-based reports across all accounts. If records are modified or disappear within a synced date range, Weld will reconcile and soft-delete stale rows in your warehouse.
  • Multi-Account Syncing: Completely refactored to support per-account incremental pointers, massively improving scalability for agencies or teams syncing multiple Google Ads accounts.
  • Smart Notifications: Targeted warning notifications if Weld loses access to a specific Google Ads customer account, while the rest of your accessible accounts continue syncing normally.

Google Analytics 4

You can now select and sync data across multiple GA4 properties simultaneously. We also added multi-account backfill streaming and improved caching to drastically reduce Google API quota consumption.

Shopify & Shopify Plus

  • Abandoned Checkouts: Now uses chunked mode for faster, more reliable syncing.
  • Transactions: Added payment_id field.
  • Fixed logic for parsing staffMembers and updated OAuth token refresh handling to prevent disconnects.

Amazon Selling Partner

  • New Stream: Added fba_inventory_summary — a history-mode stream for FBA Inventory Summary.
  • Improved error handling so that Amazon's "Data Not Ready" errors on Search Query Performance reports no longer quarantine your entire sync.

AppLovin

  • New Stream: Added hourly_advertisement_report for hourly granularity in advertisement reporting.

Microsoft Ads

  • Fixed an issue with max retention dates on reports. Corrected the MS Ads number parser.

TikTok Ads

  • Optimized syncs to run lookbacks only once a day to save resources. Fixed reporting metrics.

Google Sheets

  • Upgraded error handling to provide clear, actionable messages in the UI when Google service accounts encounter "Invalid Grant" or permission issues.

Facebook & Instagram

  • Added a delay to Facebook post comment fetching to protect your app from hitting API rate limits.
  • Fixed a bug where missing expiresIn tokens from Instagram caused sync failures.

Chargebee

  • Added plan_id field to the subscriptions table.

AWS S3

  • Added more graceful error handling and detailed logs when an S3 source stream fails.

Core ELT & CDC Improvements

  • CDC Parser Upgrades: Automatic conversion of nanosecond timestamps to milliseconds. Intelligent boolean-to-integer mapping to match Avro schemas.
  • CDC UI Safeguards: Improved state management to prevent manual triggers while a large initial CDC snapshot is still running.
  • CSV Download Optimization: Refactored the CSV download engine to handle massive queries from BigQuery, Snowflake, and Postgres with drastically lower memory usage.

Billing & Subscription Management

Migrated from Stripe Classic to Flexible billing mode, enabling:

  • Mixed-interval subscriptions — annual base plans with monthly MAR overage items within a single subscription.
  • Yearly subscriptions with monthly active row overages.
  • Detailed invoice previews with a full breakdown of your plan, included rows, and users.

Platform Fixes

  • Data Warehouse Migrator: Fixed a race condition to ensure failed migrations retry seamlessly. Added safeguards to prevent accidental BigQuery migrations within the same project.
  • User Management: Fixed an edge-case bug where the system would attempt to create duplicate user profiles during authorization.
  • Schema Validation: Fixed an issue where integrations with extremely large dropdown menus (2000+ options) would cause validation timeouts.
