The HASH_CODE is a value generated by Credibanco at the time of submitting the request and managing the equipment shipment. As explained during the session, this will serve as the identification for the APP, and it must be sent in the variable identified as HASH_CODE in the documentation.
Once the certification is complete, a Sonar test or similar will be required with 0 findings, in addition to the evidence generated during the session, to proceed with the pilot phase. (This test must be conducted using a tool configured with up-to-date code inspection methodologies. The latest scan results must be provided, not exceeding five calendar days from the last code modification. The report must show 0 security bugs, 0 vulnerabilities, and 0 security hotspots. The report should include the date to confirm that the code review was recent.)
