Update Domain Records

Partner API v2 Deprecation

Partner API v2 was deprecated on Feb 12, 2024. Please check the v3 specification for integration guides.

The Domain Actions API (Legacy) offers the functionality to generate a list of transactions that needs to be performed to update resolution records without having to form them on the client.

Step 1: Retrieve Your Reseller ID and Secret API Token

To access your ResellerID and Secret API Token, you must navigate to your Sandbox or Production Partner dashboard. The ResellerID is used to identify the requests as coming from a Partner, while the Secret API Token is used for authentication to ensure that only authorized Partners can access the API.

Step 2: Prepare Request Body

When making a domain action request, the body must contain information about your domain action in JSON format with the following structure:

    "action": "UpdateRecords",
    "parameters": {
        "records": object // resolution records to update
    "domain": string, // domain name you are updating
    "gasCompensationPolicy": string // gas compensation policy
  • action : (string) The domain action you want to perform. To update resolution records, the value should be "UpdateRecords" .
  • parameters : A key-value dictionary with additional information about the action:
    • records : A key-value pair of resolution records to configure for the domain after minting. See the Records Reference guide for supported key values.
  • domain : (string) The domain name you want to update it's records.
  • gasCompensationPolicy : (string) The gas compensation policy that should be used for the domain action.

Step 3: Prepare Authorization Headers

The Partner API uses bearer tokens to authorize requests with the Secret API Token from your Partner credentials.

Field Name Value
Security Scheme Type HTTP
HTTP Authorization Scheme bearer
Bearer Format a token provided by Unstoppable Domains

Step 4: Use the Create Domain Action Request Endpoint

Send a POST request to the Create Domain Action Request endpoint. To make a successful request, you must include the request body and authorization headers you have prepared, which should contain information about the domain action you want to perform.

Sandbox Environment:


Production Environment:


The PARTNER_RESELLERID path parameter is the same one you retrieved from your partner account earlier.


Here is an example of a request that you can use to create a domain action request to update resolution records with the following parameters:

Parameter Value
Domain Action UpdateRecords
Resolution Records {"crypto.ETH.address": "0x3EAA674612f79A97ad451fCF860A51Ad41aC2C19"}
