How We Protect Your Data

Troubleshooting
Common integration issues and how إلى fix them.
"Credentials verification failed"
Double-check you copied the full credential value معout trailing spaces. Ensure the API key/token hasn't been revoked or expired. For Twilio, the Account SID must start with 'AC'. For Stripe, Secret Key starts with 'sk_live_' or 'sk_test_'.
"WhatsApp رسائل not arriving"
Check your webhook configuration in Meta dashboard — the URL must exactly match what Engium provided. Verify you subscribed to 'رسائل' events. Also check that you used a permanent System User token (not the 24-hour test token).
"Calls not connecting via Twilio"
Ensure your Twilio number has Voice capability enabled. Check that your account has sufficient balance (trial accounts can only call verified numbers). Verify the webhook URL is accessible — check Twilio Console → Moniإلىr → Logs for error details.
"Exotel KYC is taking إلىo long"
Exotel KYC typically takes 1–2 business days. Ensure all documents (PAN, GST certificate, business address proof) are clear و legible. Contact Exotel support at support@exotel.com if it takes more than 3 days.
"Emails going إلى spam"
Set up SPF, DKIM, and DMARC DNS records for your domain. Use your provider's domain authentication feature (SendGrid → Sender Authentication, Mailgun → Domain Verification). AWS SES: request production access إلى leave sandbox mode.
"Google Calendar not syncing"
Disconnect and reconnect the calendar in Settings → Calendar. Make sure you selected the correct calendar during setup. Check that the Google account has Calendar API access enabled. Sync may take up إلى 30 seconds for new events.
"Stripe payments failing"
Verify you're using the correct key type (live vs test). Check that your Stripe account is fully activated مع business verification complete. For webhook issues, check Stripe Dashboard → Developers → Webhooks → select endpoint → see recent attempts and error details.
