### Prerequisites
|
||
|
|
|
||
|
|
In order to ingest metadata from Salesforce, you will need:
|
||
|
|
|
||
|
|
- Salesforce username, password, [security token](https://developer.Salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_concepts_security.htm) OR
|
||
|
|
- Salesforce instance url and access token/session id (suitable for one-shot ingestion only, as access token typically expires after 2 hours of inactivity)
|
||
|
|
|
||
|
|
## Integration Details
|
||
|
|
This plugin extracts Salesforce Standard and Custom Objects and their details (fields, record count, etc) from a Salesforce instance.
|
||
|
|
Python library [simple-salesforce](https://pypi.org/project/simple-salesforce/) is used for authenticating and calling [Salesforce REST API](https://developer.Salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/intro_what_is_rest_api.htm) to retrive details from Salesforce instance.
|
||
|
|
|
||
|
|
### REST API Resources used in this integration
|
||
|
|
- [Versions](https://developer.Salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_versions.htm)
|
||
|
|
- [Tooling API Query](https://developer.salesforce.com/docs/atlas.en-us.api_tooling.meta/api_tooling/intro_rest_resources.htm) on objects EntityDefinition, EntityParticle, CustomObject, CustomField
|
||
|
|
- [Record Count](https://developer.Salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_record_count.htm)
|
||
|
|
|

|
|
### Concept Mapping
|
||
|
|
|
||
|
|
This ingestion source maps the following Source System Concepts to DataHub Concepts:

| `Salesforce` | [Data Platform](../../metamodel/entities/dataPlatform.md) | |
|
||
|
|
|Standard Object | [Dataset](../../metamodel/entities/dataset.md) | subtype "Standard Object" |
|

|
|
|Custom Object | [Dataset](../../metamodel/entities/dataset.md) | subtype "Custom Object" |

### Caveats
|
||
|
|
- This connector has only been tested with Salesforce Developer Edition.
|
||
|
|
- This connector only supports table level profiling (Row and Column counts) as of now. Row counts are approximate as returned by [Salesforce RecordCount REST API](https://developer.Salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_record_count.htm).
|
||
|
|
- This integration does not support ingesting Salesforce [External Objects](https://developer.Salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_objects_external_objects.htm)
