Googlsheet & Twilio ERROR Concerns

Dear Activepieces Support,

my concern is why it doesn’t recognize the bulk numbers from my google sheet and when I test it using the connected Twilio app, It always says “Testing Failed”

I have followed the format where the numbers should be in a row and I tried the numbers to be formatted “+1” and “(690)” but it doesn’t still recognize or it always fails when I test on twilio.

This is my workflow:

PART 1: Daily SMS + Optional Slack Message (8AM every day)

Step 1: Create a New Workflow

  • Go to Activepiece Dashboard
  • Click “New Piece” or “Create Workflow”
  • Name it: Daily Leadership SMS

Step 2: Add Trigger: “Schedule”

Choose Schedule as the trigger
Set it to daily at 8:00 AM Pacific Time

Step 3: Add Action: “Twilio” – “Send SMS”

Add an Action Step → Select “Twilio”
Choose Send SMS
Connect your Twilio account (API credentials required)
Set up:
“To”: Add initial 5 numbers (you can later expand via list/loop)
“From”: Your Twilio number
“Message”: e.g., “Today’s Leadership Challenge: Lead with empathy in every interaction.”

You can also connect a Google Sheet and loop through phone numbers for scale later.

Step 4: Add Optional Slack Message

  • Add another Action Step → Select Slack
  • Choose “Send Channel Message”
  • Connect your Slack workspace
  • Choose channel and enter same daily message

PART 2: Weekly Email + Slack Challenge (Mondays)

Step 5: New Workflow: Weekly Challenge

  • Create another workflow called Weekly Leadership Challenge
  • Trigger: Schedule
  • Set to: Every Monday at 8:00 AM

Step 6: Add Kajabi Email Trigger (Optional)

  • If you prefer to trigger this via Kajabi email:
    • Use a Webhook in Activepiece
    • In Kajabi, set an email automation that triggers the webhook
    • Or use Zapier to forward Kajabi email → Gmail → Google Sheet → Trigger Activepiece

Step 7: Send Email (Optional via Mail or Kajabi)

  • If needed, connect an email app (like Gmail or SMTP) to send out the email challenge.

Step 8: Send Slack Message

  • Add Slack Action again
  • Message: e.g., “Weekly Challenge: Practice active listening during difficult conversations. Reflect by Friday.”

Optional Workarounds

If Kajabi doesn’t integrate natively:

  • Option A: Set up a Gmail address to receive Kajabi emails
  • Use a Zap or Activepiece webhook to:
    • Read the Gmail subject/body
    • Auto-log into Google Sheet
    • Use Google Sheet row update as a trigger
    • Then proceed to send Slack/SMS

Note:
when I test it on Twilio action, this will always appear:

Error: {“response”:{“status”:400,“body”:{“code”:21211,“message”:“Invalid ‘To’ Phone Number”,“more_info”:“https://www.twilio.com/docs/errors/21211",“status”:400}},“request”:{“body”:{“From”:“+16194324332”,“Body”:"Today’s Leadership Challenge: Lead with empathy. Take a moment to truly listen before you respond. Understanding builds trust.”,“To”:“{"row":1,"values":{"A":"+16199800429"}}”}}}

Is there something wrong with what I did? Let me know what I could do to fix this thanks!
