We can set automatic Capture for your pre-authorizations within needed time period. Contact your account manager or technical team to turn this function on, indicate a desired time frame.
If no Capture initiated for several days, authorization will expire. The funds will be returned to a customer and your Capture request will fail. Holding period depends on Issuer settings and usually vary from 9 till 30 days.
