1.3.0
Jul 3, 2026
blnk-go@v1.3.0 covers Blnk Core 0.15.0.

​
Identities

Delete identities from the SDK when you need to remove a customer or organization from your ledger.

​
Balance monitors

Remove balance monitors you no longer need. Blnk stops checking thresholds and sending webhooks for them.

​
Reconciliation

Start a reconciliation run and get back a reconciliation ID. Check final status with webhooks or Reconciliation.Get.

​
Transactions

Bulk create supports up to 10,000 transactions per request (MaxBulkCreateItems).

​
Error handling

Core returns structured error codes. The SDK parses them into ApiErrorResponse.ErrorDetail so you can branch on ErrorDetail.Code without parsing message text.

​
Before you upgrade

Note the following breaking changes:
  • Reconciliation.Run now returns StartReconciliationResponse with only reconciliation_id. Use webhooks or Reconciliation.Get for final status.
  • Branch on ErrorDetail.Code for Core failures. Do not parse error message text.
  • Requires Go 1.22 or later.
  • Fully backward compatible with v1.2.0 except the Reconciliation.Run return type noted above.
