# Go SDK

> Latest releases, fixes, and improvements to the Blnk Go SDK.

<Update label="1.3.0" description="Jul 3, 2026">
  <Info>
    `blnk-go@v1.3.0` covers Blnk Core **0.15.0**.
  </Info>

  ### 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.
</Update>

<Update label="1.2.0" description="Jun 26, 2026">
  ### Reconciliation

  Run instant reconciliation, fetch a run by ID, and update or delete matching rules.

  ### Identities and search

  Filter identities from the SDK. Search the `identities` collection in Typesense. `identity_id` is optional on create.

  ### Transactions

  Read transaction lineage. Recover stuck queue items. Pass `skip_queue` on inflight commit or void, bulk inflight updates, and refunds. Use `precise_distribution` on split legs.

  ### Balances

  Create balances with fund lineage tracking. Read balances with `from_source`.

  ### Client

  Configurable retry strategy for transient failures.

  ### Before you upgrade

  * Requires Go 1.22 or later.
  * Fully backward compatible with v1.1.0.
</Update>

<Update label="1.1.0" description="Jun 12, 2026">
  ### Transactions

  Bulk create transactions. Fetch a transaction by reference. Bulk commit or void up to 100 inflight transactions in one call, with support for partial commits.

  ### Balances

  Read fund lineage for a balance. Link a balance to an identity. Capture balance snapshots for historical lookups.

  ### Ledgers

  Rename a ledger without changing its ID, balances, or transaction history.

  ### Before you upgrade

  Note the following breaking changes:

  * Requires Go 1.22 or later.
  * Fully backward compatible with v1.0.1.
</Update>

<Update label="1.0.1" description="Jun 4, 2026">
  ### What's in the SDK

  Create, list, and fetch ledgers. Create and read balances, including by indicator and at a point in time. Create, fetch, commit, void, and refund transactions. Manage balance monitors. Create, fetch, list, and update identities. Upload reconciliation data, create matching rules, and start runs. Search Typesense. Update metadata on any entity.

  ### Atomic transactions

  Mark a parent transaction as atomic when you create it. Set `Atomic: true` on `ParentTransaction`.
