Hello,

Thank you for posting to the PayPal Merchant Technical Support Community.

Here are the steps to creating a product, plan, and subscription:

https://developer.paypal.com/docs/subscriptions/ --> information taken from here.

Start with creating your product:
Post here: https://api.sandbox.paypal.com/v1/catalogs/products
{
  "name": "Your Subscription",
  "description": "Type of subscription you have",
  "type": "SERVICE",
  "category": "SOFTWARE",
  "image_url": "https://example.com/streaming.jpg",
  "home_url": "https://example.com/home"
}
The response will include:

Now create the plan with the PROD Id that was returned to you:

            "rel": "self",
            "method": "POST"
        }
    ]
}
Now create the Subscription:
https://api.sandbox.paypal.com/v1/billing/subscriptions --> post here
Make sure that you update the plan_id to be the one that was given to you when you created your product. Also make sure to update the start date to the next day (or a date in the future) and not today's date. 
{
      "plan_id": "P-2G9244075A964184PLZMVHTI",
      "start_time": "2020-03-01T06:00:00Z",
      "subscriber": {
        "name": {
          "given_name": "Jimin",
          "surname": "Smith"
        },
        "email_address": "buyers.email@email.com"
      },
      "application_context": {
        "brand_name": "your product",
        "locale": "en-US",
        "shipping_preference": "SET_PROVIDED_ADDRESS",
        "user_action": "SUBSCRIBE_NOW",
        "payment_method": {
          "payer_selected": "PAYPAL",
          "payee_preferred": "IMMEDIATE_PAYMENT_REQUIRED"
        },
        "return_url": "https://example.com/returnUrl",
        "cancel_url": "https://example.com/cancelUrl"
      }
    }

You will receive a response that looks like the below. Keep in mind that this information is for sample purposes, you won't be able to use this information since it is set to a different account. Once the buyer approves the subscription then it will become active. 
{
    "status": "APPROVAL_PENDING",
    "status_update_time": "2020-02-28T18:01:23Z",
    "id": "I-3EFBDC4SV0RT",

            "rel": "approve",
            "method": "GET"
        },
        {
            "href": "https://api.sandbox.paypal.com/v1/billing/subscriptions/I-3EFBDC4SV0RZ",
            "rel": "edit",
            "method": "PATCH"
        },
        {
            "href": "https://api.sandbox.paypal.com/v1/billing/subscriptions/I-3EFBDC4SV0RZ",
            "rel": "self",
            "method": "GET"
        }
    ]
}

This is just sample created through Postman and using the PayPal API structure that was laid out in the PayPal Developer documents.

Thank you,
