NOT_AUTHORIZED returned when using /billing-agreements/agreements

[ZeenEsol]

Hi there,

I want to integrate PayPal with Chargebee, and I referred to this link: reference-transactions. According to the doc, I'm using the three APIs: 

```

1. Get Access-Token: https://api-m.sandbox.paypal.com/v1/oauth2/token

2. Create a Billing Agreement Token: https://api-m.sandbox.paypal.com/v1/billing-agreements/agreement-tokens

3. Create a Billing Agreement: https://api-m.sandbox.paypal.com/v1/billing-agreements/agreements

```

The first API always works fine, but the third reported errors from yesterday. Here is an error example for the third API:

```

{

"name": "NOT_AUTHORIZED",

"debug_id": "dbb5b44e27477",

"message": "Authorization failed due to insufficient permissions.",

"details": [

{

"issue": "NOT_AUTHORIZED",

"description": "Authorization failed due to insufficient permissions."

}

]

}

```

Below is the payload: 

```

{

"token_id": "BA-0E188861Y41092634"

}

```

Thanks!

Good day @ZeenEsol 

Thank you for posting to the PayPal community.

I would suggest to please contact your website developer or the third party eCommerce support to cross check your using same SANDBOX  REST API Credentials(Client ID & Secret) while performing the below API calls.

https://developer.paypal.com/api/rest/authentication/

https://developer.paypal.com/api/rest/postman/ 

Also, If a third-party eCommerce partner is performing API operation on your behalf, you(i.e merchant) should be on-boarded and necessary API permissions should be granted to the Partner(API Caller). 

https://developer.paypal.com/docs/multiparty/ 

https://developer.paypal.com/docs/multiparty/seller-onboarding/ 

Merchants can manually grant permission to a third-party eCommerce to access specific information in your PayPal account and perform PayPal API operations on your behalf.

Login PayPal.com >> Settings >> Account Settings >> Website payments >> API Access >> Pre-built payment solution >> Grant API permission >> contact your "Third party software eCommerce" for Third Party Permission Username >> enter the username.
