👋 Hello
Welcome to the July edition of the Weld Recap, your monthly snapshot of the latest product updates, connector improvements, and feature releases.
Product updates, improvements & fixes from the past month
July focused on streamlining syncs, tightening security, and expanding connector support across key platforms.
🔐 Snowflake: Support for key/value authentication
You can now authenticate to Snowflake using key/value pairs instead of user/password. This aligns with Snowflake's latest security recommendations and allows for more robust, secure setups.

📦 Amazon Selling Partner API: Product pricing data
We’ve added a new table to the Amazon SP connector that provides real-time product pricing based on the regional marketplace.
Note: This table reflects the price as it appears in the relevant marketplace (e.g., prices in the German marketplace include German VAT).

📊 Facebook Ads: Custom click and view windows
When setting up a Facebook Ads data source, you can now choose the click_window and view_window to reflect how your ads are tracked. This allows for more accurate attribution modeling in your reporting.

🏦 Facebook Conversion API: Improved lead data
Reverse ETL syncs to Facebook Conversion API now support user data in leads. That means better match rates and more effective campaign targeting.

ELT: Klaviyo segment series supported as custom report
You can now access Klaviyo segment series as a custom report in Weld. Ideal for building tailored reports and lifecycle marketing dashboards.

⌚ Search across all syncs
Quickly access any sync, whether it’s a data source, model, or reverse ETL sync, using the search bar.

Use ⌘ + K (Mac) or Ctrl + K (Windows/Linux) to open the search dialog, or find it in the sidebar. Now includes syncs across all sync types.
⚙️ Orchestration improvements
We’ve rolled out a few orchestration updates based on feedback from our users:
- You can now rename orchestrations
- Add descriptions to each orchestration
- Enable/disable orchestrations as needed
More improvements are on the way, but this is a big step forward.
📁 PostgreSQL: Edit your warehouse connection
You can now easily update your PostgreSQL data warehouse connection from the Account → Data Warehouse menu. No need to redo your setup from scratch.
📈 New blog posts & resources
✏️ How to build a data pipeline with Python + Weld
We published a complete tutorial and video guide on how to set up a Weld data pipeline using Python and Google Cloud Run, with Typeform as an example source.
⚖️ ETL vs ELT: What’s the difference?
Understand how cloud platforms and flexible workflows are shaping the shift from ETL to ELT, and how your stack should evolve.
⚡️ Why data pipelines keep breaking
Learn the real reasons behind brittle pipelines and what you can do about it, including schema changes, state handling, and dependency management.
🛋️ Until next time
