We are currently integrating with the Purchase Shipping Labels API (https://api.veeqo.com/shipping/shipments). However, when we try to purchase a label through the documented , the API always returns:
{
"error_messages": [
":rate_code parameter is missing"
]
}
or this one:
{
"error_messages": [
"Not found"
]
}
We need use “carrier”: “amazon_shipping_v2”, so how can we setup this API?
Does API label purchasing currently restricted to whitelisted accounts in US? If yes, how can our account be added to the whitelist / how can we request activation of this feature?
Thanks for anybody help!
