Create External Contact (crypto Or Fiat)
Creates a new contact. The body field type discriminates: crypto saves a crypto address, fiat saves an AR/ARS banking account. Both modes are idempotent — if an equivalent contact already exists it is returned without creating a duplicate.
When type=fiat, only entity_number (CVU/CBU/alias) is accepted.
The otp_code field is required in the request body for both modes.
NOTE: The contact is automatically created as whitelisted, meaning it will not require OTP for operations.
Authorization
- Requires a valid API key.
Headers

A timestamp in milliseconds. See the Timestamp Security section for more details.
An additional, non-required parameter, that you can send to specify the number of milliseconds after the timestamp for the request to be valid. See the Timestamp Security section for more details.
Body
