[Ashishyadav1]

Hi 

I have created the subscription plan with below payload:-

{
"product_id": "PROD-39T93926CP7625608",
"name": "Netflix Plan",
"description": "Netflix Basic Plan",
"status": "ACTIVE",
"usage_type": "LICENSED",
"billing_cycles": [
{
"tenure_type": "REGULAR",
"sequence": 1,
"total_cycles": 12,
"frequency": {
"interval_unit": "MONTH",
"interval_count": 1
},
"pricing_scheme": {
"fixed_price": {
"currency_code": "USD",
"value": "20"
}
}
}
],
"payment_preferences": {
"auto_bill_outstanding": true,
"setup_fee_failure_action": "CONTINUE",
"payment_failure_threshold": 3,
"setup_fee": {
"value": "0",
"currency_code": "USD"
},
"service_type": "PREPAID"
},
"taxes": {

}
}  

After successfully created the subscription plan. 

Now created the subscription for checkout:-

I was created successfully and got the links in response.

"links" :[{
"href": "https://api.sandbox.paypal.com/v1/billing/subscriptions/I-P991F8S8KN5V",
"rel": "edit",
"method": "PATCH"
}, {
"href": "https://api.sandbox.paypal.com/v1/billing/subscriptions/I-P991F8S8KN5V",
"rel": "self",
"method": "GET"
}, {
"href": "https://www.sandbox.paypal.com/webapps/billing/subscriptions?ba_token\u003dBA-46M94926X0815490K",
"rel": "approve",
"method": "GET"
}]

@Ashishyadav1 

This seems to be an issue with your API or if it's your custom development then an argument is not passed correctly. Are you using WOO and WP or is that something else, custom PHP may be? Do you have logging enabled for this PayPal API call so that you can track where its breaking?

Please check and let me know.

Thank!
