[SOLVED] PayPal Transaction Search API: PERMISSION_DENIED, No Permission for the requested operation

Issue

I'm writing a service (in .NET Core 3.1 and Refit if it matters) that pulls transaction activities from my PayPal business account for a given date range to use on an admin dashboard. Currently I'm following the tutorial here:

https://developer.paypal.com/docs/api/get-an-access-token-postman/

and here:

https://developer.paypal.com/docs/api/transaction-search/v1/

The first part, I can get an authorization key just fine (using curl or postman, curl below

curl --location --request POST 'https://api.paypal.com/v1/oauth2/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Basic <my client id>:<my secret>' \
--header 'Content-Type: application/x-www-form-urlencoded' \

// not sure what this is, postman specific maybe? 
--header 'Cookie: tsrce=devdiscoverynodeweb; ts=vr%3D0cee9361171ac120001362adffec14c3%26vreXpYrS%3D1679730671%26vteXpYrS%3D1585061694%26vt%3D0cee9390171ac120001362adffec14c2' \
--data-urlencode 'grant_type=client_credentials'

This gives me an auth token both in postman and my custom service just fine. Next, when I try to pull the transactions (both in Postman and in code), I get an error

cUrl:

curl --location --request GET 'https://api.paypal.com/v1/reporting/transactions?start_date=2020-03-01T00:00:00Z&end_date=2020-03-31T23:59:59Z' \
--header 'Authorization: Bearer <my token>' \
// Postman???
--header 'Cookie: tsrce=devdiscoverynodeweb; ts=vr%3D0cee9361171ac120001362adffec14c3%26vreXpYrS%3D1679730671%26vteXpYrS%3D1585061694%26vt%3D0cee9390171ac120001362adffec14c2'

Error:

{
    "localizedMessage": "No permission for the requested operation. ",
    "suppressed": [],
    "name": "PERMISSION_DENIED",
    "message": "No permission for the requested operation. ",
    "details": [
        {
            "field": null,
            "value": null,
            "location": null,
            "issue": "No permission for the requested operation. "
        }
    ],
    "information_link": "https://developer.paypal.com/docs/classic/products/permissions/",
    "debug_id": "7e315038e8073"
}

The info link in the error starts talking about 3rd party permissions, which I'm not sure is applicable because it is my Business account. Anyone have any ideas? I checked transaction history on my app in PayPal, so I'm at a lost.

Thanks in advance


Solution

You need the scope https://uri.paypal.com/services/reporting/search/read .. if it's not there in the oauth2 response, double check your REST App's permissions.

Refreshing an access token

Existing access tokens are cached for 9 hours--so if you already requested an API token and then just added this permission to your app, it can take up to 9 hours for that permission's new scope to be reflected in the next token's generation.

To avoid waiting 9 hours, you can terminate that existing cached token with:

curl -X POST https://api.sandbox.paypal.com/v1/oauth2/token/terminate \
     -u "yourclientid:yoursecret" \
     -d "token=REPLACE_WITH_YOUR_TOKEN"

After termination, your next call to get a token will get a newly-generated one, including the new scope that was just added to the REST app.
