Bulk Import

The Bulk Import endpoint allows you to import multiple customers, plans, invoices, line items, transactions, and subscription events with a single API query.

The Bulk Import endpoint is an alternative to importing data via Import API single-object endpoints (such as Create a Customer or Import Invoices).

The Bulk Import endpoint is useful when:

  • You only want to import data without listing, updating, or deleting objects
  • You need to import many objects at once (e.g. more than 100)

Use Import API single-object endpoints (or a combination of the Bulk Import and single-object endpoints) when:

  • In addition to importing data, you want to list, update, or delete objects
  • You need to import a relatively small number of objects (e.g. fewer than 100)

Comparison of the Bulk Import and single-object endpoints

Importing 100 customers with corresponding invoices, plans, and subscription events requires 200–300 single-object API requests. Importing these objects with the Bulk Import endpoint uses one API query.

Here’s the list of differences between the Bulk Import endpoint and Import API single-object endpoints:

FunctionalityBulk ImportImport API single-object endpoints
Object validationValidation of imported objects runs asynchronously after the import. Invalid objects are imported and marked as Failed in ChartMogul Data PlatformValidation runs synchronously during the API request. API requests with invalid objects are rejected immediately with an appropriate HTTP response.
Multiple objects in a single API requestYes, which substantially reduces the number of API requests.Only some endpoints (e.g. Import Invoices allow multiple objects of the same type in a single API query.
Objects referencing ChartMogul UUIDs or external IDsObjects that reference another object (e.g. an invoice requiring a reference to the invoiced customer) are referenced solely by external IDs.API query parameters and objects that reference other objects require ChartMogul UUIDs. In most cases, this means you need an additional List API request to fetch the generated UUID.
Import/List/Update/DeleteSupports only the import of objects. Does not support listing, updating, or deleting imported objects.Supports the import of objects as well as listing, updating, and deleting imported objects.
