Instant Update API should be available for Express Checkout in live / production mode.
In sandbox mode everything works well
- PayPal requests the URL, and then displays the flat rate shipping options -,
but in live / production mode PayPal doesn't request the URL at all,
the rest of checkout process works well.
I assured that all requirements are met for CallbackURL in live / production mode:
How can I find out the reason why PayPal in live / production doesn't request the URL?
Correlation ID of a an Express Checkout
which should use Instant Update API (but does not in live / production mode):
Thank you for your answers in advance.
With best regards
I'm having the same issue. PayPal is not calling my callback url in production. I'm saying that after i've checked the access logs.
This is quite frustraiting, I've spend hours to make it work using the sandbox, and then even some more hours investingating in production.
PayPal Express Checkout API is such a waist of time.
