Missing required oauth parameter:

[ham]

This is the header i am sending to FatSecret

oauth_consumer_key=my_consumer_public_key, oauth_nonce=1300071440524,
oauth_signature=signature_generated oauth_signature_method=HMAC-SHA1,
oauth_timestamp=1300071440, oauth_version=1.0

And this is the response i am getting.

<?xml version="1.0" encoding="utf-8" ?><error xmlns="http://
platform.fatsecret.com/api/1.0/" xmlns:xsi="http://www.w3.org/2001/
XMLSchema-instance" xsi:schemaLocation="http://platform.fatsecret.com/
api/1.0/ http://platform.fatsecret.com/api/1.0/fatsecret.xsd">
<code>2</code> <message>Missing required oauth parameter:
oauth_signature_method</message></error>


Can anyone please help me narrow down the problem.
SInce in the header i am sending oauth_signature_method=HMAC-SHA.

[ham]

hi,
i figured that one out since there was a missing method .
now my new header is

food_id=4384&method=food.get&oauth_consumer_key=MY_API_KEY&oauth_nonce=1300075545711&oauth_signature=prg
%2F7fJgAFtkqTmNSWgP6VaRvrE%3D&oauth_signature_method=HMAC-
SHA1&oauth_timestamp=1300075545&oauth_version=1.

i get signature is invalid....

Can some one give me hints to what can be wrong.?
I am using java Api to generate signature
//calculate signature value
Mac m = Mac.getInstance("HmacSHA1");
m.init(new SecretKeySpec(CONSUMER_SECRET.getBytes(),
"HmacSHA1"));
m.update(signature_base_string.getBytes());
byte[] res = m.doFinal();
String sig = Base64.encodeBytes(res);
sig = URLEncoder.encode(sig,"UTF-8");

The signature i get is rg%2F7fJgAFtkqTmNSWgP6VaRvrE%3D

Do i need to URLEncode the base64encoded string as well?
Well without that also i get same error.
Invalid signature: oauth_signature

Hi Ham,
Sorry it took so long - are you getting fat secret data yet ?

Can anybody suggest me, where am I fault, pls?

on my request I have that response:

'Missing required parameter: oauth_consumer_key'

My code:

----------------------

url_api = 'https://www.fatsecret.com/oauth/request_token'
http_method = 'GET'

Consumer_Key = '***'
Consumer_Secret = '***'

Access_Secret = ''

grant_type = 'client_credentials'

params = {'oauth_consumer_key':Consumer_Key,
          'oauth_signature_method':'HMAC-SHA1',
          'oauth_timestamp':str(int(time.time())),
          'oauth_nonce':'1234',
          'oauth_version':'1.0',
          'oauth_callback':'oob'
         }

def create_signature(secret_key, signature_base_string):
    encoded_string = signature_base_string.encode()
    encoded_key = secret_key.encode()
    temp = hmac.new(encoded_key, encoded_string, hashlib.sha1).hexdigest()
    byte_array = b64encode(binascii.unhexlify(temp))
    return byte_array.decode()

params_normalized = urllib.parse.urlencode(sorted(params.items()))
params_encoded = urllib.parse.quote(params_normalized, safe='')

url_api_encoded = urllib.parse.quote(url_api, safe='')

Signature_Base_String = '&'.join([http_method, url_api_encoded, params_encoded])

signing_key = Consumer_Secret + '&' + Access_Secret

oauth_signature = create_signature(signing_key, Signature_Base_String)
oauth_signature_encoded = urllib.parse.quote(oauth_signature, safe='')

body = {'grant_type' : grant_type}

autorization = ','.join([f'OAuth oauth_consumer_key="{params["oauth_consumer_key"]}"',

headers = {
            'Content-Type' : 'application/x-www-form-urlencoded',
            'Authorization' : autorization
          }

response = requests.post(url_api, data=body, headers=headers)

I will be grateful for your any advice

Hi there,

Thanks for reaching out. We recommend using Postman first to test the API and to also validate your authentication.

https://www.postman.com/fatsecret

Then you can use these for your own app/backend.

Kind regards,

The FatSecret Platform API Team
