Preparing files for MWS
The Feeds API works with files. To submit data into MWS using the Feeds API, you need to do the following:
Step 1. Create a flow which extracts data from a third party API or database and creates files that can be uploaded into MWS.
Step 2. Create a flow which submits the files prepared in step 1 to MWS.
Step 3. Combine the flows created in steps 1 and 2 into a single nested flow.
Configuring data formats for the Feeds API
The Feeds API accepts data in two formats: XML and Tab-delimited flat files. Each feed type requires its own template. For simplicity, we will be describing only flat files in this documentation. Read more about the available flat file templates.
Below is an example of a typical flat file for office supplies (to see a more readable version, copy and paste it into your favorite text editor):

As you can see, the first 2 lines are part of the template and cannot be changed. The third line contains the column headers, and the rest is data. Let's configure the format for a Tab-delimited file with a header so that it can be understood by the Amazon MWS Feeds API.
Step 1. Go to Connections->Formats and click the + button. Type csv into the Search field.
Step 2. Select the CSV format and configure the parameters.
1) Select Tab as the Delimiter.
2) Enter " as the Quote.
3) Enter 3 as the Start Row.
4) Select Header as Transformation type.
5) Copy and paste the text below into Filter or Preprocessor or Header:

Step 3. Save the format. It can now be used when creating flat files that can be understood by the Amazon MWS Feeds API.
Creating a flow to prepare input files for the Feeds API.
Step 1. Create a source (FROM) connection. It can be a Database connection, Cloud storage, File storage or a Web service.
Step 2. Create a Server Storage connection. Use this as the destination (TO) connection.
Step 3. Depending on your source (the place you are pulling data from), select one of the following flow types:
Database to file
or Web service to file
or File to file
Step 4. Continue by configuring a Transformation, where the source (FROM) connection is the connection created in step 1, the destination (TO) connection is the connection created in step 2, and the destination (TO) format is a format defined here. In the TO field, enter the name of the file to create, for example inventory.txt.
Step 5. Configure the Mapping and Parameters for the transformation.
Amazon limits the size of the file you can upload through the Feeds API to 1 GB and approximately 30,000 records. If you expect to upload large files, it is recommended that you split them into smaller chunks. Integrator can automatically split files if you set the property Partition By. Go to Mapping->Additional Transformations->Partition By and set Partition By to whatever number of records you want Integrator to split your file by. The number must be less than 30K. For example, if you expect your source dataset to have 100K records, but MWS can only load 30K at one time, you need to set Partition By to 30K. If, for example, the file name is inventory.txt, Integrator will create 4 files: inventory_1.txt (30K records), inventory_2.txt (30K records), inventory_3.txt (30K records) and inventory_4.txt (10K records).
Creating a flow which submits files into the Feeds API.
Step 1. Create an Amazon MWS Feeds connection. Use this as the source (FROM) connection.
Step 2. Start creating the flow in Flows window by typing upload data into Amazon MWS into the search field.
Step 3. Configure a Transformation, where the source (FROM) connection is the Server Storage connection that was created for the first flow, where FROM is a wildcard file name which matches the original file name, for example: inventory.txt->inventory*.txt, the destination (TO) connection is the connection created in step 1 and, finally, TO is any string, for example inventory.
Step 4. Set the flow parameters by clicking Mapping->Parameters. The following parameters are available:
Action - select Move if you want to delete the source files after they are submitted to MWS or Copy if you want to keep them.
Wait before making next API call - if there are multiple files to upload, this parameter is used to prevent throttling. If the value is greater than 0, multi-threading will be disabled regardless of the value of the property Maximum Simultaneous Operations.
Maximum Simultaneous Operations - if there are multiple files to upload, they can be uploaded in simultaneous parallel threads. This parameter controls the maximum number of simultaneous submit operations allowed. It is recommended that you use the default value, which is 1.
Putting it all together
Combine flows 1 and 2 into a single nested flow.
You have now created a flow which:
1) Extracts data from the source and creates files to upload.
2) Uploads files into MWS.
