Correlation IDs

The x-correlation-id is a custom header that you can add to the Send Document request.

For example:

curl --request POST \
     --url https://e-invoicing-service.vertexcloud.com/customers/v1/documents \
     --header 'accept: application/json' \
     --header 'content-type: multipart/form-data' \
     --header 'x-correlation-id: ABC123' \
     --form payload='@Sample_invoice_file_for_Italy_multiple_line_items.xml'

This value is returned in the headers of responses and is useful for debugging,
