Before getting started make sure to set your Polytomic API key as an environment variable:

```bash
export POLYTOMIC_API_KEY=YOUR-API-TOKEN
```

This example tutorial will cover three steps:

1. Connecting to Salesforce.
2. Connecting to S3.
3. Loading data from Salesforce into S3.

## 1. Create a Salesforce connection

The following request will create a Salesforce connection. The configuration for each type of connection can be found at the [connection configuration](https://apidocs.polytomic.com/2023-04-25/configuring-your-connections) page.

```bash
curl --request POST  \
     --url https://app.polytomic.com/api/connections \
     --header "accept: application/json"  \
     --header "content-type: application/json"  \
     --header "X-Polytomic-Version: 2023-04-25"   \
     --header "Authorization: Bearer ${POLYTOMIC_API_KEY}"  \
     -d '{"name": "Salesforce Connection","type": "salesforce", "configuration": {"domain": "https://example.my.salesforce.com"}}
```

Since Salesforce connections uses OAuth to authenticate, we'll need to follow the link returned in the `auth_url` parameter in the response

#### Redirection

\


> **Note**
>
> By default, the API expects the `auth_url` to be opened in a new browser window. If you'd like to modify the redirect behavior, there is an optional `redirect_url` parameter that can be added to the request body.

## 2. Create an S3 connection

The S3 bucket must be network-accessible from Polytomic. For more information, see our [S3 Connection Guide](https://docs.polytomic.com/docs/aws-s3-connections).

```bash
     curl --request POST \
     --url https://app.polytomic.com/api/connections \
     --header "accept: application/json" \
     --header "content-type: application/json" \
     --header "X-Polytomic-Version: 2023-04-25"  \
     --header "Authorization: Bearer ${POLYTOMIC_API_KEY}" \
     -d '{
     "name": "S3 Connection",
     "type": "s3",
     "configuration": {
        "aws_access_key_id": "EXAMPLE",
        "aws_secret_access_key": "SECRET",
        "s3_bucket_region": "us-east-1",
        "s3_bucket_name": "my-bucket"
        }
    }'
```

## 3. Create a bulk sync

This will create a bulk sync of the `Account` and `Contact` Salesforce objects into S3:

\


> **Note**
>
> Important: If the schemas parameter is omitted, all objects will be synced.

\


```bash
curl --request POST \
     --url https://app.polytomic.com/api/bulk/syncs \
     --header "accept: application/json" \
     --header "content-type: application/json" \
     --header "X-Polytomic-Version: 2023-04-25" \
     --header "Authorization: Bearer ${POLYTOMIC_API_KEY}" \
     -d '{
          "name": "Salesforce Bulk Sync",
          "source_connection_id": "YOUR-SALESFORCE-CONNECTION-ID",
          "destination_connection_id": "YOUR-S3-CONNECTION-ID",
          "mode": "replicate",
          "schedule": {
              "frequency": "manual"
          },
          "destination_configuration": {
               "format": "csv"
          },
          "schemas": ["Account", "Contact"]
    	}'
```

#### Bulk sync schemas

\


> **Note**
>
> Polytomic may take a few moments to cache source schemas after creating new connections. The message `{"status":400,"message":"No schemas found. This can mean that the Polytomic has not cached any schemas yet. Please try again.","metadata":null}` indicates that the schemas are not ready to be used in bulk sync configuration yet. This request is safe to retry until receiving a 2xx response.
