Upload Proof Document is an authenticated API call that allows submission of a user’s source of income document proof as part of the KYC verification process. This step is required when Enhanced KYC is triggered and Source of income is submitted.
Valid proof documents (e.g., passport, national ID, driver’s license, or utility bill) must be submitted after completing the submission of Source of income Form.
Note: Any invalid, unclear, or missing documents may lead to KYC verification failure or delays in completing the onboarding process.
