amazon-product-api

I am getting this error though I am not making multiple calls at a time. My first call itself has thrown this error as per my log. Same API call is working after some time. Please guide me how to solve this issue.

Function usage:

var client = amazon.createClient({ awsId: "XXXXXXXXXXXXXXXXXXX", awsSecret: "YYYYYYYYYYYYYYYYYYYYYYY", awsTag: "ZZZZZZZZZZZZZZ" });

console.log("Before making Amazon API"); client.itemLookup({ idType: 'ASIN', itemId: BBBBBBBBBB, //This is valid amazon ASIN id domain: 'webservices.amazon.in' }).then(function (results) { var result = JSON.stringify(results); console.log("amaz success" + result);

    res.send(result);
}).catch(function (err) {
console.log("amaz error" + err);
var result = JSON.stringify(err);
result = "ErrorOccured" + result;
    res.send(result);        
});

Error:

{"$":{"xmlns":"http://ecs.amazonaws.com/doc/2013-08-01/"},"Error":[{"Code":["RequestThrottled"],"Message":["AWS Access Key ID: XXXXXXXXXXXXXXXX. You are submitting requests too quickly. Please retry your requests at a slower rate."]}],"RequestID":["5b1b2a16-1870-4884-9543-26d463955d94"]}"

Same issue, and i'm running code manually, very slowly. Here there are some info about limit (http://docs.aws.amazon.com/AWSECommerceService/latest/DG/TroubleshootingApplications.html)

Check this issue https://github.com/t3chnoboy/amazon-product-api/issues/37

Same issue,

I only execute one request in my code:

const amazon = require('amazon-product-api');
const credentials = require('./credentials.json');

const client = amazon.createClient(credentials);

client.itemSearch({
    director: 'Quentin Tarantino',
    actor: 'Samuel L. Jackson',
    searchIndex: 'DVD',
    audienceRating: 'R',
    responseGroup: 'ItemAttributes,Offers,Images',
}).then((results) => {
    console.log('OK');
    console.log(results);
}).catch((err) => {
    console.log('ERROR');
    console.log(err.Error);
});

Error: [ { Code: [ 'RequestThrottled' ], Message: [ 'AWS Access Key ID: XXXXXXXXXXXXXXXXXXX. You are submitting requests too quickly. Please retry your requests at a slower rate.' ] } ]

Solved adding the domain in request:

domain: 'webservices.amazon.es'

how to add this

Solved using https://github.com/jhurliman/node-rate-limiter

Something like:

const RateLimiter = require('limiter').RateLimiter;
const limiter = new RateLimiter(1, 2000);

limiter.removeTokens(1, function() {
 client.itemLookup({...})
})

Might be related to some changes made to their API operating agreement.

https://docs.aws.amazon.com/AWSECommerceService/latest/DG/TroubleshootingApplications.html

Note that your account will lose access to Product Advertising API if it has not generated referring sales for a consecutive 30-day period.

I also read that in order to qualify access you need to make three sales, although I can not find that at this time.

Found it:

https://associates.amazon.ca/assoc_credentials/home

How do I get access to PA API? In order to qualify for requesting access to PA API, you will need an associate account, you will have to complete three qualifying sales in the first 180 days and you will have to comply with the Operating Agreement. Once your account has been approved as an associate account, you will see a 'Request for PA API access' button below. You can click the button to get access to PA API.
