}KYC
Submit verification data
First call in the KYC API flow. Nothing else is accepted before it: country is what routes the customer to their country’s requirements.
Answers 202, not 200. We validate the request before we answer and record it with the verification provider after. A 202 means accepted, not satisfied. Read the result from the kycUpdated webhook or GET /organization/{organizationId}/kyc?requirements=true.
Submitting again overwrites what was sent before, and never moves the customer’s review status on its own. Personal organizations only.

}Authorizations
API key sent in the Authorization header, with no Bearer prefix.
Path Parameters
The organization this call acts for: your API key's organization or one of its customer organizations. Any other id returns 404 not-found.
Body
application/json
Personal data a partner submits on the customer's behalf. A Mexican customer (country: "MEX") needs a CURP and RFC to complete verification.
YYYY-MM-DD. Any other format is a 400.
Example:
"1990-01-01"
The customer's tax identification number. The RFC for a Mexican customer.
Example:
"XAXX010101000"
The customer's country, as an ISO 3166-1 alpha-3 code. Alpha-2 codes and country names are rejected. This is the one country field for the customer (there is no separate nationality), and its value routes them to their country's requirements.
Example:
"MEX"
The customer's residential address. Required, and it must match the identity document you upload; the provider cross-checks the two.
