Limitation of frequency requests to Amazon Advertising API

Now the Advertising API often getting below error

Amazon API call error. You are submitting requests too quickly. Please retry your requests at a slower rate.

It seems Amazon has changed the access limits to API. This message is not blocking the process completely, some requests should pass through.

First, you need to decrease the number of threads. This issue quite clearly states, that your account limits have been reached. The only way to avoid this message is to decrease the number of requests per moment of time.

There is not much we can do to remove the issue, that is the new API limitation. So there is a way to increase limits, but this is a request to the Amazon service.

We guess you can get higher limits if you contact Amazon.

The good news is that all you see on a product page on Amazon can be extracted using HTML parser. This script will import all product details from any Amazon site.

I want to get Amazon data

Amazon Advertising API

Amazon Advertising API is developed to give you to request the Amazon catalog, either with search keywords or by choosing specific products and extract information about those items.

With Amazon Advertising API you can get access to a lot of Amazon data including the products for sale, customer reviews, price, quantity as well as most of the information you see on Amazon.com pages.

Product Advertising API operations allow you to take advantage of Amazon's complex e-commerce data, data analysis, and functionality.

We have a combined experience of over eight years within custom web development and e-commerce software. For the last five years, our focus has mostly been around web data extraction and web analytics.

Some questions regarding setup of the Amazon Data Extraction Engine

Q: How many Amazon products can your system scrap per hour? I see that your system takes about 2.4 seconds per article. Is it possible to use another proxy to scrap articles even faster?

A: Yes. The speed is totally a matter of website capacity. You can put it into 100 threads, which will update 50 products per second. The software is designed to update price and stock as fast as you require. To run 100 threads, you will need a dedicated server.

Q: How long is the license when I buy it?

A: There are no license limitations. You get it and it works on your server. We provide new versions as long as the project continues.

If you need customizations, we provide them for an additional price. Since the software is not simple and depends on the scraping websites structure, it usually requires some support. And most of our clients eventually go to a small monthly payment for a timely support. Or you can handle it with your own developers.

Q: Can the data be put in the mysql database? Or can the scheme be adapted to the other webshop?

A: The data is stored in the mysql database. We install the software on your server and you can get a direct access to the database. It is possible to build some connectors, which will deploy data for your webshop.

Q: Is there any way that you do not have to manually synchronize the product data? The first time there is only ASIN, I need not have to do it manually and download everything.

A: The data is synced by the cron script, so the product data is updated automatically. Yes, asin goes first; it will populate other data after the first synchronization.

Q: It takes a long time to update the products; would there be any way to update them by groups/categories in cron tasks?

A: You may add more cron commands to the tab to speed up the synchronization process. The link should be like this: {} The option a=x makes a delay in seconds before the process starts. This way we can start more processes every minute.

Q: I need to download the data four times a day. Can you explain how to do that? How can I schedule the automatic csv download to another server or ftp?

A: We can set it up in a frame of the service. We can create a controller, which can be triggered by cron and send data to a server. Or you can call the link which generates CSV files.

Q: When does an active product go to the state “move to active”?

A: "Move to active" is one of the sync statuses, and you control in which status the product is. When you import products, you can specify the status.

We have created several statuses to distinguish products. You can import products into “Move to active”; they will be synced once. You can review their prices and decide if you need them in Active state.

Active means full syncing state. For example, move to active products ignore parsing offers settings and sync only with product page.

Q: In what order do you synchronize products again? The oldest ones first?

A: Once a product is synced, it gets next_update_date field put into the future date. Once this date becomes past, the system can put it into the queue of the next update. If the queue moves fast enough, usually the queue is not big; i.e., parser updates products right in time. Regarding next_update_date, each product also has a field sync_speed. Some products might be updated more often, though this depends on how often each product is likely to change price and stock. If price and stock do not change, the product is updated with bigger delays.

Amazon has changed a logic related to offers pages serving. Which blocked simple access to offers page.

Why scrapers cannot scrape Amazon offers page?

When you do a search, you can see that a product has some offers. If you click "offers" link, you can see all the offers. However, if you just inserted a link to the offers page into a browser and went to the product offers page, you would likely get an empty offers page.

You can't see offers page until you have some browsing history. We discovered that Amazon Data Extraction Engine could not see offers page because the offers page is blank if the visitor does not have certain cookies.

In this case, rotating proxies would not work, since we need to preserve cookies.

Important Amazon Data Extraction Engine update

Amazon tracks cookies for the offer page now. The only way to scrape offers by a robot is to generate a user-like behavior. It requires a reverse request order (first product page, second offers page) because offers page is always retrieved after the product page for the real browsing.

Our parser already works with cookies.

We have a combined experience of over 8 years within custom web development and e-commerce software. For the last 5 years, our focus has mostly been around web data extraction and web analytics.

Use case: parsing results from the search results page

Crawl, extract and parse content from some target websites. Desired behavior for the script: load search phrases list from file provided by customer and automatically enter the search window of each site. Obtain the necessary items and images from the search result page. Data acquisition is done on a regular basis.

We have created parsing profiles for target sites. The Data Extraction Engine acquires data and images of search results (product pages) obtained on the target site using the list of search phrases.

Parsing profiles have complicated logic as there are some cases where search results represented as a branch to reaching the data.

The parser gets a list of all branches and parses its output. We have created some basic profile, which makes the search and gets the poster of the product and related information such as product title, item description, product images, screenshot.

The nature of this web data extraction work is confidential.

We have a combined experience of over 8 years within web analytics, custom web development, SEO and IT. For the last 5 years, our focus has mostly been around web analytics and web data extraction.

Some questions regarding setup of the Web Data Extraction Engine

Q: Could you please respond to the addition or change of functions as needed? Also, can you respond to changes in the display composition etc. of data acquisition target site?

A: The parser is developed keeping in mind that html structure is not a constang, therefore most of the parsing settings are handled in the xml files. And most of the changes can be obtained by changing those xml instructions.

We will continue handling the software. We usually estimate all tasks and do them in a small less than $1000 chunks.

Q: Are there any costs and running costs other than those suggested?

A: Initial payment is $590. You need a server on which the parser will work and proxy account.

VPS even not big is ok for the start, it should be an Apache, PHP, MySQL. The parser is not very heavy, the big resources are required to get a lot of threads.

Proxy is required to run the parser. You need to obtain a rotating proxy account. For example, Stormproxies provide an account of 40 threads for $40/mo.

If you want to test parser, you may probably take the initial proxy account from Proxyrotator, they provide it for < $10/mo, it would be enough for some tests.

40 threads proxy would allow to do like 40 html pages per second parsed. Regarding Amazon parsing - it would be like 1 mln products parsed a day. It should be enough for average load. But you do not need proxy right from the start, only when we finish some of your parsing profile.

So, you need a server on which the parser will work and proxy account. Nothing else is needed.

Q: Can we protect our project with NDA?

A: Of course, we can do it and we can legally agree to keep our work private. Confidentiality refers to protecting information. We can't share confidential work without permission.

*Synthesized Speech: Amazon Polly

Two years ago Amazon started to shrink the usage of the API. If Amazon Magento Extension was able to handle import/sync using HTML parsing itself two years ago, now we need to have a separate tool implemented in the Amazon Data Extraction Engine as a stand-alone project, which is not connected with Magento and does not use API to work.

What is the Solution? Connected Magento + Engine

General usage

You keep your inventory in Magneto, use Amazon Magento Extension to find new products, the Engine keeps stock and price updated. Right now, the Engine has a simple product search function. From this point, Magento might be used without Amazon Magento Extension.

This solution allows you to scale inventory size and does not rely on the API

Now we have clients who use the Engine interface to manage products. Magento just connects the inventory to Seller Central, and the Engine manages products on Magento: create/modify/delete automatically. If you remove products from Engine they are automatically removed from Magento.

In order to have the Engine working with 100k-300k products, you need to have a dedicated server with a rotating proxy account. That monthly price will be around $150/mo. If you need more products, we also can discuss this.

After installation and setup, which is included in the package, we also can handle a server management.

Here, we're going to look at the pros and cons of each in more detail, to help you make an informed decision. Check out this info to get a clearer view of the realities of software as a service.

Designing and creating the extraction process is one of the most time-consuming tasks in the data extraction process in both variants.

Software-as-a-Service (SaaS)

There are a proliferation of techniques and technology of automated methods of data capturing, each suitable for a particular type data or source of data. Let's be clear here. We're talking about the business subscribes to an application it accesses over the Internet.
