Hey Thomas, happy to hear it's been working well. A few questions to help debug.
What did you use as the new value?
Can you send what error message you received?
Can you send the x-request-id for the request?

In the end i had to switch to a custom webhook request in Zapier - as in a normal POST the tool makes any values a string.... so when it came to numCards i had to specify it as a numerical value
