GraphQL to REST API Migration Guide

Authentication Changes

Previous: GraphQL API token
New: REST API token generated from the Customer Hub
Action Required: Generate a new token from the Customer Hub before migration

Endpoint Changes

Previous GraphQL: https://api.justt.ai/merchant-graph
New REST: https://api.justt.ai/v1/chargebacks

Request Format Changes

Previous GraphQL Format

POST https://api.justt.ai/merchant-graph
{
  "query": "mutation createChargeback($input: CreateChargebackInput!) {
    createChargeback(input: $input) {
      id
      status
    }
  }",
  "variables": {
    "input": {
      // Your chargeback data here
    }
  }
}

New REST Format

POST https://api.justt.ai/v1/chargebacks
{
  // Your chargeback data here with updated parameter names
}

Parameter Mapping

When migrating your requests, ensure you update the parameter names while keeping the same values:

GraphQL Parameter	REST Parameter	Notes
[Old Param Name]	[New Param Name]	Same value used

Error Handling

GraphQL returned errors in the errors array
REST API uses standard HTTP status codes with error details in the response body

Migration Checklist

Generate new REST API token from Customer Hub
