Live site data

### **Introduction** Welcome to the **Accelera Data Integration API** documentation. Before posting member records to our system, please refer to the **Prerequisites** section below, which outlines the necessary authorization and header authentication requirements. Next, set up the initial data as described in the [Data Enum](#ab582893-cd02-4577-a164-f103560db695) and [Selection Option](#550f5127-2592-4d86-bc15-7b216c237b3b) sections. These values will be used when posting member records, such as `member_status`, `game_id`, and `rebate_type`. Once the setup is complete, you are ready to post member records: - To post **ongoing** or **recent (within the last 4 months) member records**, refer to the [Member Record](#d7a84ad1-a93c-4893-bb67-d5f37435520b) section. - To post **compressed member records** (Member Daily Total Calculation) refer to the [Daily Member LifeCycle](#7cd09932-15bc-4211-9919-8c9ce5e19ed1) section. ### Prerequisites We use **Basic Auth** for authorization, where: - The **username** is the **Merchant Code**. - The **password** is the **API Password** (request when necessary). Additionally, the `Identifier` header is required in each request. This should contain a **Base64-encoded** string of your `username:password` values, appended to the text **Basic**, as shown below: ``` javascript identifier: Basic {Base64-encoded-username-password} ``` Next, the following additional header data is required to identify merchant information: ### Header Info | **Header** | **Type** | **Description** | **Example Value** | | --- | --- | --- | --- | | `merchant` | String | Merchant Code to identifies the merchant making the request. | `merchant_code` | | `currency` | String | Sets the currency format. | `PHP` | | `timezone` | String | Specifies the client
