Paypal UNSUPPORTED_MEDIA_TYPE

问题

I am trying to get an access token from paypal's authorization api. When I make post request to the api I get UNSUPPORTED_MEDIA_TYPE i.e. 415 response.

Below is the snippet that I used.

const auth = await fetch(PAYPAL_OAUTH_API, {
    method: 'post',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': `Basic ${ basicAuth }`
    },
    body: JSON.stringify({"grant_type": "client_credentials"})
});

I have fixed my issue by setting Content-Type to application/x-www-form-urlencoded.

My guess is paypal accepts only application/x-www-form-urlencoded for authorization api.

I ran into same issue, and the solution is following (using Postman):

1. Select POST
2. Add Token into Authorization, type is Bearer-Token
3. Select Content-Type: application/json in headers
4. Use RAW as body, and in TEXT dropdown, select JSON (application/JSON)
5. Copy body as raw object and change info accordingly.

Step 4 and 5 are what solved the error, you must send raw json object.
