Airtable ‘Update Record’ Step Fails with ‘Not Found’ — Even Though Record ID is Correct from Webhook

Hey everyone, I’m running into a frustrating issue with my Zap that connects Airtable and Zapier.

Here’s the setup:

• I’m using an Airtable automation with a button in the interface to run a script.

• That script sends a Webhook to Zapier that includes the recordId, companyName, contactName, and email from the Customers table.

• In Zapier, the webhook trigger receives the recordId correctly (in the format C-recXXXXX).

• I then try to update that record in Airtable using the “Update Record” action and pass the recordId to the Record ID field.

Here’s the issue:
When I test the Zap, I get the following error:

“Failed to create a record in Airtable. The app returned ‘Not Found.’”

Things I’ve already checked:

• The recordId is definitely correct and exists in the Airtable table.

• I’ve confirmed that the correct Base and Table are selected in the “Update Record” step.

• I tried hardcoding the Record ID manually and that worked — but dynamically pulling from the webhook does not.

• The checkbox field I’m trying to update is called Advertiser Agreement Sent and I’m passing true to it.

• I’ve reconnected my Airtable account just in case.

It feels like Zapier isn’t correctly passing the recordId from the webhook step into the update action, but I can’t figure out what I’m doing wrong.

Any help or ideas would be massively appreciated!
