After careful consideration, we decided to end support for Amazon FinSpace, effective October 7, 2026. Amazon FinSpace will no longer accept new customers beginning October 7, 2025. As an existing customer with an Amazon FinSpace environment created before October 7, 2025, you can continue to use the service as normal. After October 7, 2026, you will no longer be able to use Amazon FinSpace. For more information, see [Amazon FinSpace end of support](https://docs.aws.amazon.com/finspace/latest/data-api/amazon-finspace-end-of-support.html). 

# UpdateChangeset

## Request Syntax
<a name="API_UpdateChangeset_RequestSyntax"></a>

```
PUT /datasets/datasetId/changesetsv2/changesetId HTTP/1.1
Content-type: application/json

{
   "clientToken": "string",
   "formatParams": { 
      "string" : "string" 
   },
   "sourceParams": { 
      "string" : "string" 
   }
}
```

## URI Request Parameters
<a name="API_UpdateChangeset_RequestParameters"></a>

The request uses the following URI parameters.

 ** [changesetId](#API_UpdateChangeset_RequestSyntax) **   <a name="finspace-UpdateChangeset-request-uri-changesetId"></a>
The unique identifier for the Changeset to update.  
Length Constraints: Minimum length of 1. Maximum length of 26.  
Required: Yes

 ** [datasetId](#API_UpdateChangeset_RequestSyntax) **   <a name="finspace-UpdateChangeset-request-uri-datasetId"></a>
The unique identifier for the FinSpace Dataset in which the Changeset is created.  
Length Constraints: Minimum length of 1. Maximum length of 26.  
Required: Yes

## Request Body
<a name="API_UpdateChangeset_RequestBody"></a>

The request accepts the following data in JSON format.

 ** [formatParams](#API_UpdateChangeset_RequestSyntax) **   <a name="finspace-UpdateChangeset-request-formatParams"></a>
Options that define the structure of the source file(s) including the format type (`formatType`), header row (`withHeader`), data separation character (`separator`) and the type of compression (`compression`).   
 `formatType` is a required attribute and can have the following values:   
+  `PARQUET` – Parquet source file format.
+  `CSV` – CSV source file format.
+  `JSON` – JSON source file format.
+  `XML` – XML source file format.
Here is an example of how you could specify the `formatParams`:  
 ` "formatParams": { "formatType": "CSV", "withHeader": "true", "separator": ",", "compression":"None" } `   
Note that if you only provide `formatType` as `CSV`, the rest of the attributes will automatically default to CSV values as following:  
 ` { "withHeader": "true", "separator": "," } `   
 For more information about supported file formats, see [Supported Data Types and File Formats](https://docs.aws.amazon.com/finspace/latest/userguide/supported-data-types.html) in the FinSpace User Guide.  
Type: String to string map  
Key Length Constraints: Maximum length of 128.  
Key Pattern: `[\s\S]*\S[\s\S]*`   
Value Length Constraints: Maximum length of 1000.  
Value Pattern: `[\s\S]*\S[\s\S]*`   
Required: Yes

 ** [sourceParams](#API_UpdateChangeset_RequestSyntax) **   <a name="finspace-UpdateChangeset-request-sourceParams"></a>
Options that define the location of the data being ingested (`s3SourcePath`) and the source of the changeset (`sourceType`).  
Both `s3SourcePath` and `sourceType` are required attributes.  
Here is an example of how you could specify the `sourceParams`:  
 ` "sourceParams": { "s3SourcePath": "s3://finspace-landing-us-east-2-bk7gcfvitndqa6ebnvys4d/scratch/wr5hh8pwkpqqkxa4sxrmcw/ingestion/equity.csv", "sourceType": "S3" } `   
The S3 path that you specify must allow the FinSpace role access. To do that, you first need to configure the IAM policy on S3 bucket. For more information, see [Loading data from an Amazon S3 Bucket using the FinSpace API](https://docs.aws.amazon.com/finspace/latest/data-api/fs-using-the-finspace-api.html#access-s3-buckets)section.
