Overview

Metadata allows you to attach custom information to various ledger components, including ledgers, balances, identities, and transactions.

With the Update Metadata endpoint, you can modify existing metadata or add new metadata to an item after it has been created.

​
How it works

1

Initial metadata

Consider the following metadata attached to an item:

{
  ...
  "meta_data": {
    "first_name": "Jason"
  }
}
2

Adding more metadata

To add a last name and verification status, send a POST request to:

POST YOUR_BLNK_INSTANCE_URL/{id}/metadata
Request
{
  "meta_data": {
    "last_name": "Brooks",
    "verification_status": "Pending"
  }
}
3

Updating metadata

To update the verification status, send the following request:

POST YOUR_BLNK_INSTANCE_URL/{id}/metadata
Request
{
  "meta_data": {
    "verification_status": "Approved"
  }
}
4

Final metadata

After these updates, the metadata for the item will look like this:

{
  ...
  "meta_data": {
    "first_name": "Jason"
  }
}
