Airtable API error
Hey everyone, I’m stuck with an Airtable API call in Voiceflow and I hope someone can point me in the right direction.
I’m currently at the API call step in the first template of the “Master Voiceflow in 2 Hours” tutorial, but I can’t get the request to work.
Voiceflow keeps showing this error:
“Can’t send request – Make sure the domain is publicly available or try a different URL.”
Important details:
– The request never reaches Airtable (so I’m not getting any 400/401 Airtable errors).
– The URL format I’m using is:
https://api.airtable.com/v0/<BASE_ID>/<TABLE_NAME>
– Personal Access Token is newly created and linked to the correct base.
– Headers:
Authorization: Bearer PATTOKEN
Content-Type: application/json
– JSON body is valid.
– I tried a new base, a new table, and a new token — still the same issue.
– Voiceflow only works for me in an incognito window, but even there this API call fails.
It seems like Voiceflow isn’t even sending the request, but I can’t figure out what’s blocking it.
Has anyone experienced this before or knows what might be causing it?
Thanks in advance!
