Pendencies API (Partner)
API intended for partners to query onboarding/accreditation pendencies of a Merchant (EC). The goal is to expose a minimum, stable, and secure contract, allowing the partner to identify: (1) which pendencies exist for the EC and (2) the status of each pendency. For pendencies of type DATA_GRID, the response includes the list of registration attributes (gridInfo) that must be reviewed/resolved by the partner, indicating which ones are required.
