Airtel has communicated that the existing SMS API endpoint (https://openapi.airtel.in) will be discontinued and customers must migrate to the new Airtel IQ SMS API endpoints hosted at https://iqsms.airtel.in.

Key Details:

• Old Endpoint (to be deprecated):
  https://openapi.airtel.in/gateway/airtel-iq-sms-utility/sendSms
• New Default Endpoint (mandatory):
  https://iqsms.airtel.in/api/v1/send-sms

Other Available New Endpoints:

• Send SMS to multiple numbers (same content):
  https://iqsms.airtel.in/api/v1/send-sms-multi
• Send SMS via CSV:
  https://iqsms.airtel.in/api/v1/send-sms-csv
• Send bulk SMS (different content per request):
  https://iqsms.airtel.in/api/v1/send-sms-bulk
• Send SMS with content moderation:
  https://iqsms.airtel.in/api/v1/send-sms-cm

Important Notes:

• There is no change in authentication method or request payload.
• Only the API endpoint URL changes.
• Migration is required to avoid SMS service disruption once the old endpoint is shut down.
• Airtel recommends completing the transition at the earliest.

Action Required:

• Confirm whether the development team has already been informed.
• Update all SMS integrations to use the new iqsms.airtel.in endpoints.
• Validate SMS functionality post-migration.
