Deprecated. Send ip_address in POST /verifications instead (or in each item of POST /verifications/bulk). This endpoint keeps working until November 15, 2026, when it is removed.

Registers a consent for an identifier. Accepts an 18-char CURP (individual) or a 12-char RFC (business). The payload is the same in both cases.

A consent expires 365 days after creation. After that, POST /verifications for the identifier returns consent_expired until you create a new consent. Data from verifications already completed can still be read.
