Issues with Adding Custom Variables in Instantly Campaigns

Hi guys, I've got an issue with sending a campaign to Instantly via the built-in integration. I have a campaign in Instantly. I'm trying to add custom variables to it in addition to the ones already in the campaign and they don't appear in Instantly (although I don't see any errors in Clay). The only way it works is when I push all the custom variables as a single batch to a fresh campaign.

The issue with custom variables not appearing in Instantly when added to an existing campaign via the Clay integration is likely due to API limitations. Custom variables must already be added to the campaign in Instantly via an import before they can be used in Clay. To resolve this: 1. Ensure all custom variables are first added to your Instantly campaign through a manual import. 2. Re-run the Clay enrichment after updating the data in your table. 3. Add a conditional run setting to only execute if all variables are present. For future campaigns, consider including personalized lines or custom snippets when initially setting up the campaign in Instantly. If you need further assistance, please request human support by clicking on "Talk to a person" in this chat.
