Bulk Card Operations Overview

Modulr's Bulk Card Operations feature lets you create, edit, or cancel up to 1,000 virtual cards at once by uploading a single CSV file.

Whether you need to update card limits for modified bookings, reissue expired cards, or issue cards for a supplier switching to virtual card payments, this feature saves you time and reduces errors by eliminating repetitive manual entry.

When to use Bulk Card Operations

Bulk Card Operations is ideal when you need to handle multiple cards at once:

  • Update card limits when booking values change due to guest modifications or additional charges
  • Reissue expired cards when suppliers forget to take payment before the card expires
  • Recover from API issues by manually processing operations that failed to create, update, or cancel
  • Issue cards for supplier verification when suppliers verify cards exist by charging a small amount (e.g., €1)
  • Switch payment methods by issuing virtual cards for suppliers who are moving from account-to-account payments
  • Perform maintenance and correct errors across multiple cards

What you can do

  • Process multiple operation types in one file. Create, edit, and cancel cards together
  • Set any card field you can configure in the UI or API, including custom fields
  • Share card details automatically with suppliers (if you have Secure Card Sharing enabled)
  • Review before processing. Spot and fix errors before processing your batch
  • Process partially. Choose to submit only the valid entries while you fix others

How it works

  1. Prepare your CSV file with all the card operations you need to perform
  2. Upload the file to the Modulr portal
  3. Review the operations. See all entries in a table, with errors highlighted at the top
  4. Process the operations. Submit all valid operations for processing
  5. Monitor progress. Track processing status and view a summary when complete

If you have Secure Card Sharing enabled, card details are automatically sent to supplier email addresses you include in the CSV.
