POST /employers/{employer_id}/contributions

O auth2 client credentials

Create multiple contributions for a specified employer in a single request. Asynchronous — the response is an Upload object representing queued work, not a final result. Contribution identifiers are not available in this response; poll GET /uploads/{upload_id} until the status is terminal, then fetch contributions via GET /uploads/{upload_id}/contributions and any errors via GET /uploads/{upload_id}/errors. Processing is idempotent per pay period: re-submitting the same records will only process those not already created successfully — the recommended way to recover from a PartiallyProcessed upload.

Hide response attributes Show response attributes object
- id string Required
  
  ID of the upload.
- employer_id string | null
  
  ID of the employer the upload was made for.
- put_destination_url string | null Required
  
  Destination URL where the actual file should be sent, using a PUT request. Only present when status is AwaitingFile. We recommend using the AWS S3 client SDK to perform the upload.
- created_at string(date-time) Required
  
  Datetime the upload was created.
- updated_at string(date-time) Required
  
  Datetime the upload was last updated.
- processing_started string(date-time) | null Required
  
  Datetime of when processing of the file began.
- processing_ended string(date-time) | null Required
  
  Datetime of when processing of the file ended, or null if it has not ended.
- processing_time number | null Required
  
  The number of seconds it took to process the file end-to-end (if applicable).
- total_errors number Required
  
  The number of errors produced in processing the file. Zero if there are none or processing is not finished. Use the {upload_id}/errors endpoint to retrieve detailed information of the errors.
- contributions_created number Required
  
  The number of contributions created during processing. Zero if processing is not finished.
- contributions_unprocessed number
  
  The number of contributions that failed to be created during processing. Zero if processing is not finished.
- contributions_already_existed number Required
  
  The number of contributions that already existed prior to processing, and which have been skipped during processing of the upload. Zero if processing is not finished.
- employer_contributions number Required
  
  The total of employer contributions created for the upload, excluding contributions that already existed. Zero if processing is not finished.
- employee_contributions number Required
  
  The total of employee contributions created for the upload, excluding contributions that already existed. Zero if processing is not finished.
- total_contributions number Required
  
  The total of contributions created for the upload, excluding contributions that already existed. Zero if processing is not finished.
- filename string | null Required
  
  The filename of the uploaded file (if applicable).
- status string Required
  
  The status of the upload. Error indicates the file was not able to be processed. PartiallyProcessed indicates that validation passed and processing ran eagerly, but some records succeeded while others produced errors — treat this status as incomplete and re-submit the failing records (or the entire file) to recover. Processing is idempotent per pay period, so successfully-processed records will be skipped on re-submission. To retrieve the errors for an Error or PartiallyProcessed upload, use the /uploads/{upload_id}/errors endpoint.
  
  Values are AwaitingFile, ReceivedFile, Processing, Processed, Error, Timeout, or PartiallyProcessed.
