Trouble mapping custom product page links into automated Gmail shipping updates

Hello, I am building a workflow to send custom post-purchase care emails to customers via Gmail after they buy specific premium gear from our site.

I want the email to dynamically include the exact care instructions link based on what they bought. For example, if they purchase a technical item like this forclaz jackets, they need a specific care guide link injected into the body text.

Right now, I have a Lookup Table step in Zapier to match the product name to the URL, but the Zap keeps failing at the Gmail step, saying the mapped output field is empty. It seems like the lookup isn't matching the exact text string properly.

Has anyone faced this issue with Lookup Tables? Is it better to use a Webhook or Python code block instead to parse the product name? Thank you!

Hi ​@forclaz00,

 

I've run into this before, and I'd still recommend sticking with the Lookup Table. The Gmail error usually means the product name isn't matching exactly, it might be extra spaces or capitalization.

I'd avoid switching to Python unless you really need to. A Lookup Table is much easier to maintain since adding or updating products is just a table edit instead of requiring someone to modify the Zap and republish it. I'd also consider matching on a product ID or SKU instead of the product name if possible.

 

Hope this helps!

Hi ​@forclaz00 

For us to have more info, post screenshots showing how your Zap steps are outlined and configured in the CONFIGURE tab while in EDIT mode with the field mappings visible.
