# Get Sender Information API Reference

`GET https://staging.eko.in/ekoapi/v3/customer/payment/ppi-levin/sender/{customer_id}`

Fetch a PPI Levin sender's wallet profile and onboarding/OTP state by mobile number.

First step of the PPI Levin flow. For an enrolled sender the response returns an `otp_ref_id` and asks you to validate the OTP (call Verify Sender OTP). If the customer is not enrolled (response_type_id 308), proceed to Onboard Sender.
