BI data source v1 — ElasticSearch

Deprecation notice

We're announcing the deprecation of BI Data Source API v1, effective after July 31st, 2024. This means v1 will no longer be actively supported in future updates and will be suspended by October 31st, 2024. In its place, we're introducing BI Data Source API v2, built on OpenSearch for improved functionality and performance.

BI data source API v2 offers a high degree of compatibility with v1. Due to the potential impact of the change, we are releasing this as a non-backward compatible change, and provide clients the possibility to perform integration testing against the new v2 endpoint until October 31st, 2024.

To ensure a smooth transition, we highly recommend verifying your current integration with v1. The new v2 API is already available for use.

Here's what you need to do​

The initial released BI data source API v1 is marked as deprecated after July 31st 2024, and we are releasing v2, which is based on OpenSearch.

  • Review the BI Data Source API v2 documentation.
  • Change your API endpoints from /query/transactions to /query/transactions/v2
    • Your current API key will continue to work with the new API version.
  • Test your integration with the new API.
  • Make any necessary adjustments to your code.
What will happen if I do nothing?​

By the end of the deprecation period, we will switch the current API endpoint to the OpenSearch API. This means the current endpoint /query/transactions will start serving the same responses as the /query/transactions/v2. However, /query/transactions/v2 will still be available after the switch.

Please see BI data source v2 for further information.

Connectivity and authentication​

You can access the BI data source through these endpoints:

  • For production: https://bds.ixopay.com/query/transactions
  • For sandbox: https://sandboxbds.ixopay.com/query/transactions

Each request to the BI data source must be authenticated using BASIC Authentication credentials. Here, the username is the API Key, and the password is the API Key's password. You can refer to the API Key section of our user manual for more information on creating an API Key.

Querying the BI data source​

The BI data source is built on ElasticSearch 7.10 service, providing robust querying and search operations. It enables you to perform powerful data analysis on the stored transaction information.

You can use a wide range of query and search operations as described in the ElasticSearch 7.10 documentation. Here are some useful resources:

ElasticSearch:

For a more granular understanding of how to query the BI data source, please refer to the Example Queries and ElasticSearch Schema sections. These resources contain detailed examples and the specific ElasticSearch schema used by the IXOPAY platform, which will guide you on how to effectively use this feature.

Example queries​

Below, you'll find a set of example queries you can execute on the BI data source to serve various use cases:

Example 1: Finding a specific transaction​

Retrieve a particular transaction using its UUID:

curl --request GET \
     --url 'https://bds.ixopay.com/query/transactions?q=uuid:12345678901234567890' \
     --user '$BI_API_KEY:$BI_PASSWORD'

Example 2: Count transactions by status (in the last 24 hours)​

Aggregate transactions based on their status within the past 24 hours:

curl --request POST \
     --url 'https://bds.ixopay.com/query/Transactions' \
     --header 'Content-Type: application/json; utf-8' \
     --user '$BI_API_KEY:$BI_PASSWORD' \
     --data '
{
  "aggs": {
    "status_aggregation": {
      "terms": {
        "field": "status",
        "min_doc_count": 1,
        "order": {
          "_term": "asc"
        },
        "size": 500
      }
    }
  },
  "query": {
    "bool": {
      "filter": [
        {
          "range": {
            "created_at": {
              "format": "epoch_millis",
              "gte": "now-24h",
              "lte": "now"
            }
          }
        }
      ]
    }
  },
  "size": 0
}'

Example 3: Volume of transactions per method & currency (in the last month)​

Determine the total volume of transactions per payment method and currency over the previous month:

curl --request POST \
     --url 'https://bds.ixopay.com/query/Transactions' \
     --header 'Content-Type: application/json; utf-8' \
     --user '$BI_API_KEY:$BI_PASSWORD' \
     --data '
{
  "aggs": {
    "method_aggregation": {
      "terms": {
        "field": "method",
        "min_doc_count": 1,
        "order": {
          "_term": "asc"
        },
        "size": 100
      },
      "aggs": {
        "currencies": {
          "terms": {
            "field": "currency",
            "min_doc_count": 1,
            "size": 100
          },
          "aggs": {
            "volume": {
              "sum": {
                "field": "amount"
              }
            }
          }
        }
      }
    }
  },
  "query": {
    "bool": {
      "filter": [
        {
          "range": {
            "created_at": {
              "format": "epoch_millis",
              "gte": "now-1M",
              "lte": "now"
            }
          }
        }
      ]
    }
  },
  "size": 0
}'

These examples illustrate the power and flexibility of querying the BI data source on IXOPAY. Using these queries, you can retrieve, aggregate, and analyze your transaction data effectively.

Forward compatibility​

note

The information provided in this section is for informational purposes only. The exact terms and conditions governing the IXOPAY platform BI data source are defined in the applicable contract. For any clarifications or questions regarding specific terms and conditions, please refer to the signed contract.

  • API compatibility: We maintain compatibility with one of the currently supported ElasticSearch versions to ensure ongoing integration with your existing systems.
  • Changes:
    • Non-backward compatible changes: When significant changes to the data model necessitate non-backward compatibility (for example, modifications to existing data fields, structure, or API semantics), we will introduce a new API version. The previous API version will be phased out two months following the announcement of the new version to allow ample time for integrators to migrate.
    • Backward compatible changes: Changes that maintain backward compatibility (for example, addition of new optional fields) will be implemented without the need for a new API version and will not require any notifications or specific action from integrators.
  • Data integrity: Data provided through the IXOPAY platform BI data source is intended for use as a query and data source for BI systems, but absolute data consistency is not guaranteed. This means that there may be occasional discrepancies between the data provided by the API and the underlying data sources.
  • Data latency: Data is not provided in real time but generally within 24 hours. This is due to data processing and validation requirements.
  • Data changeability: Data provided through the API is subject to change due to factors such as chargebacks, settlements, and updates from underlying systems. Integrators should account for this potential for data changes in their applications.
