In this section, we provide guides and references to use the Salesforce connector.

Configure and schedule Salesforce metadata and profiler workflows from the OpenMetadata UI:

- [Requirements](#requirements)
- [Metadata Ingestion](#metadata-ingestion)

## Requirements

{%inlineCallout icon="description" bold="OpenMetadata 0.12 or later" href="/deployment"%}
To deploy OpenMetadata, check the Deployment guides.
{%/inlineCallout%}

To run the Ingestion via the UI you'll need to use the OpenMetadata Ingestion Container, which comes shipped with
custom Airflow plugins to handle the workflow deployment.


Following are the permissions you will require to fetch the metadata from Salesforce.

**API Access**: You must have the API Enabled permission in your Salesforce organization.

**Object Permissions**: You must have read access to the Salesforce objects that you want to ingest.

### Python Requirements

To run the Salesforce ingestion, you will need to install:

```bash
pip3 install "openmetadata-ingestion[salesforce]"
```

## Metadata Ingestion

All connectors are defined as JSON Schemas.
[Here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/entity/services/connections/database/salesforceConnection.json)
you can find the structure to create a connection to Salesforce.

In order to create and run a Metadata Ingestion workflow, we will follow
the steps to create a YAML configuration able to connect to the source,
process the Entities if needed, and reach the OpenMetadata server.

The workflow is modeled around the following
[JSON Schema](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/workflow.json)

### 1. Define the YAML Config

This is a sample config for Salesforce:

{% codePreview %}

{% codeInfoContainer %}

#### Source Configuration - Service Connection

{% codeInfo srNumber=1 %}

**username**: Username to connect to the Salesforce. This user should have the access as defined in requirements.

{% /codeInfo %}

{% codeInfo srNumber=2 %}

**password**: Password to connect to Salesforce.

{% /codeInfo %}


{% codeInfo srNumber=4 %}

**securityToken**: Salesforce Security Token is required to access the metadata through APIs. You can checkout [this doc](https://help.salesforce.com/s/articleView?id=sf.user_security_token.htm&type=5) on how to get the security token.

{% /codeInfo %}

{% codeInfo srNumber=5 %}

**sobjectName**: Specify the Salesforce Object Name in case you want to ingest a specific object.  If left blank, we will ingest all the Objects.

{% /codeInfo %}

{% codeInfo srNumber=6 %}

**salesforceApiVersion**: Follow the steps mentioned [here](https://help.salesforce.com/s/articleView?id=000386929&type=1) to get the API version. Enter the numerical value in the field, For example `42.0`.

{% /codeInfo %}

{% codeInfo srNumber=7 %}

**salesforceDomain**: When connecting to Salesforce, you can specify the domain to use for accessing the platform. The common domains include `login` and `test`, and you can also utilize Salesforce My Domain.
By default, the domain `login` is used for accessing Salesforce.

{% /codeInfo %}

#### Source Configuration - Source Config

{% codeInfo srNumber=10 %}

The `sourceConfig` is defined [here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/databaseServiceMetadataPipeline.json):

**markDeletedTables**: To flag tables as soft-deleted if they are not present anymore in the source system.

**includeTables**: true or false, to ingest table data. Default is true.

**includeViews**: true or false, to ingest views definitions.

**databaseFilterPattern**, **schemaFilterPattern**, **tableFilternPattern**: Note that the filter supports regex as include or exclude. You can find examples [here](/connectors/ingestion/workflows/metadata/filter-patterns/database)

{% /codeInfo %}

#### Sink Configuration

{% codeInfo srNumber=11 %}

To send the metadata to OpenMetadata, it needs to be specified as `type: metadata-rest`.

{% /codeInfo %}

{% partial file="workflow-config.md" /%}

#### Advanced Configuration

{% codeInfo srNumber=8 %}

**Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

{% /codeInfo %}

{% codeInfo srNumber=9 %}

**Connection Arguments (Optional)**: Enter the details for any additional connection arguments such as security or protocol configs that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

- In case you are using Single-Sign-On (SSO) for authentication, add the `authenticator` details in the Connection Arguments as a Key-Value pair as follows: `"authenticator" : "sso_login_url"`

{% /codeInfo %}

{% /codeInfoContainer %}

{% codeBlock fileName="filename.yaml" %}

  serviceName: local_salesforce

```yaml {% srNumber=11 %}
sink:
  type: metadata-rest
  config: {}
```

### 2. Prepare the Ingestion DAG

Create a Python file in your Airflow DAGs directory with the following contents:

{% codePreview %}

{% codeInfoContainer %}


{% codeInfo srNumber=13 %}

#### Import necessary modules

The `Workflow` class that is being imported is a part of a metadata ingestion framework, which defines a process of getting data from different sources and ingesting it into a central metadata repository.

Here we are also importing all the basic requirements to parse YAMLs, handle dates and build our DAG.

{% /codeInfo %}

{% codeInfo srNumber=14 %}

**Default arguments for all tasks in the Airflow DAG.** 

- Default arguments dictionary contains default arguments for tasks in the DAG, including the owner's name, email address, number of retries, retry delay, and execution timeout.

{% /codeInfo %}

{% codeInfo srNumber=15 %}

- **config**: Specifies config for the metadata ingestion as we prepare above.

{% /codeInfo %}

{% codeInfo srNumber=16 %}

- **metadata_ingestion_workflow()**: This code defines a function `metadata_ingestion_workflow()` that loads a YAML configuration, creates a `Workflow` object, executes the workflow, checks its status, prints the status to the console, and stops the workflow.

{% /codeInfo %}

{% codeInfo srNumber=17 %}

- **DAG**: creates a DAG using the Airflow framework, and tune the DAG configurations to whatever fits with your requirements
- For more Airflow DAGs creation details visit [here](https://airflow.apache.org/docs/apache-airflow/stable/core-concepts/dags.html#declaring-a-dag).

{% /codeInfo %}

Note that from connector to connector, this recipe will always be the same.
By updating the `YAML configuration`, you will be able to extract metadata from different sources.

{% /codeInfoContainer %}

{% codeBlock fileName="filename.py" %}

```python {% srNumber=13 %}
import pathlib
import yaml
from datetime import timedelta
from airflow import DAG
from metadata.config.common import load_config_file
from metadata.ingestion.api.workflow import Workflow
from airflow.utils.dates import days_ago

```python {% srNumber=14 %}

    "email_on_failure": False,

    "retry_delay": timedelta(minutes=5),
    "execution_timeout": timedelta(minutes=60)

```

```python {% srNumber=15 %}

    workflow = Workflow.create(workflow_config)
    workflow.execute()
    workflow.raise_from_status()
    workflow.print_status()
    workflow.stop()


```

```python {% srNumber=17 %}

    "sample_data",
    default_args=default_args,

    start_date=days_ago(1),
    is_paused_upon_creation=False,
    schedule_interval='*/5 * * * *',
    catchup=False,
) as dag:
    ingest_task = PythonOperator(
        task_id="ingest_using_recipe",
        python_callable=metadata_ingestion_workflow,
    )
