# Base de Clientes as a data source
> Bring data from Base de Clientes to Nekt.
Base de Clientes is a subscription and billing management platform for Brazilian merchants. It supports recurring billing, receivables, transfers, customer management, contracts, and reporting. Data is extracted via the Base de Clientes REST API using a Bearer token.
## Configuring Base de Clientes as a Source
In the [Sources](https://app.nekt.ai/sources) tab, click on the "Add source" button located on the top right of your screen. Then, select the **Base de Clientes** option from the list of connectors.
Click **Next** and you'll be prompted to add your access.
### 1. Add account access
You'll need to provide your Base de Clientes API credentials so Nekt can access your data.
The following configurations are available:
* **Auth Token**: (Required) Bearer token for the Base de Clientes API. Obtain it from [suporte@clientbase.com.br](mailto:suporte@clientbase.com.br). This token authenticates all API requests.
* **Start Date**: (Optional) Initial date for incremental sync. Used on the first run when there is no bookmark. Example: `2020-01-01T00:00:00Z`. Streams with incremental sync (billings, banks, recurrences, receivables, transfers, contracts, announcement\_portals) will filter records by `updated_at` greater than this date on the first extraction.
Once you're done, click **Next**.
### 2. Select streams
Choose which data streams you want to sync. For faster extractions, select only the streams that are relevant to your analysis. You can select entire groups of streams or pick specific ones.
> Tip: The stream can be found more easily by typing its name.
Select the streams and click **Next**.
### 3. Configure data streams
Customize how you want your data to appear in your catalog. Select the desired layer where the data will be placed, a folder to organize it inside the layer, a name for each table (which will effectively contain the fetched data), and the type of sync.
* **Layer**: Choose between the existing layers on your catalog. This is where you will find your new extracted tables as the extraction runs successfully.
* **Folder**: A folder can be created inside the selected layer to group all tables being created from this new data source.
* **Table name**: We suggest a name, but feel free to customize it. You have the option to add a **prefix** to all tables at once and make this process faster!
* **Sync Type**: You can choose between INCREMENTAL and FULL\_TABLE.
* **Incremental**: Every time the extraction happens, we'll get only the new or updated data. Supported for **banks**, **billings**, **contracts**, **receivables**, **recurrences**, **transfers**, and **announcement\_portals** (they use `updated_at` as replication key).
* **Full table**: Every time the extraction happens, we'll get the current state of the data. Used for **bank\_accounts**, **customers**, **customer\_groups**, **custom\_fields**, **merchant\_users**, and **reports**.
Once you are done configuring, click **Next**.
### 4. Configure data source
Describe your data source for easy identification within your organization, not exceeding 140 characters.
To define your [Trigger](https://docs.nekt.com/get-started/core-concepts/triggers), consider how often you want data to be extracted from this source. This decision usually depends on how frequently you need the new table data updated (every day, once a week, or only at specific times).
Optionally, you can define some additional settings:
* Configure Delta Log Retention and determine for how long we should store old states of this table as it gets updated. Read more about this resource [here](https://docs.nekt.com/get-started/core-concepts/resource-control).
* Determine when to execute an **Additional [Full Sync](https://docs.nekt.com/get-started/core-concepts/types-of-sync#additional-full-sync)**.
Once you are ready, click **Next** to finalize the setup.
### 5. Check your new source
You can view your new source on the [Sources](https://app.nekt.ai/sources) page. If needed, manually trigger the source extraction by clicking on the arrow button. Once executed, your data will appear in your Catalog.
For you to be able to see it on your [Catalog](https://app.nekt.ai/catalog), you need at least one successful source run.

# Data Model
The following diagram illustrates the main relationships between Base de Clientes streams. **Merchant** is the central entity; **customers** and **merchant\_users** belong to it. **Billings** and **recurrences** link to customers. **Receivables** tie billings to **transfers**. **Bank accounts** and **banks** support transfers. **Contracts** associate customers with contract models. **Customer groups** group customers. **Reports** and **announcement\_portals** are merchant-scoped.

# Implementation Notes
### Authentication
* The tap uses **Bearer token** authentication. The `auth_token` is sent in the `Authorization` header for all API requests.
### Incremental Sync
* Streams with `replication_key = "updated_at"` support incremental sync. On the first run (no bookmark), the tap uses `start_date` from config to filter records. On subsequent runs, the bookmark from state is used.
### Numeric Fields as Strings
* Several amount and value fields (`amount_billed`, `amount_paid`, `amount`, etc.) are stored as strings in the schema because the API can return them as strings or numbers. Use `CAST(column AS DOUBLE)` or equivalent in SQL for aggregations.
### JSON String Fields
* Fields like `metadata`, `custom_fields`, `tags`, `billing_items`, `product`, `paymentable`, and similar are serialized as JSON strings for compatibility with the data lake. Use `JSON_EXTRACT` or equivalent to parse them in queries.
